Development of efficient sunlight conversion materials is critical for advancing sustainable agricultural practices, but current solutions often face challenges such as poor stability, high cost, and reliance on rare-earth elements. This study presents a rare-earth-free xCsMnCl 3 (H 2 O) 2 /(1−x)Cs 3 SbCl 6 heterojunction ( x = 1−0.65) synthesized via an eco-friendly mechanochemical method. By strategically combining Cs 3 SbCl 6 as a UV-absorbing donor with CsMnCl 3 (H 2 O) 2 as an efficient red emitter. The optimized heterojunction achieves a remarkable 36-fold enhancement at 626 nm (Full width at half maxima (FWHM) = 88 nm), perfectly matching chlorophyll a's absorption spectrum. Comprehensive experimental and theoretical analyses, including UV–vis absorption, photoluminescence (PL) spectroscopy, and density functional theory (DFT) calculations, reveal a dual enhancement mechanism: i) efficient interfacial electron-hole transfer and ii) suppression of non-radiative recombination through defect passivation. The practical application is demonstrated through a sunlight conversion film fabricated by embedding the 0.75CsMnCl 3 (H 2 O) 2 /0.25Cs 3 SbCl 6 composite in Ecoflex-0030, which exhibits exceptional environmental stability (90% PL retention after 90 days) and mechanical durability (500% tensile strain). The plant growth experiments confirm the film's agricultural efficacy, with chives and green cabbage growth rates increasing by 1.5- and 1.3-fold, respectively, compared to natural light conditions. This work not only addresses the limitations of existing light-conversion materials but also establishes a rare-earth-free, eco-friendly platform for energy-efficient agriculture.

Compared to conventional organic electrolytes, aqueous magnesium-ion batteries (AMIBs) have emerged as a research hotspot due to their superior safety, environmental compatibility, and cost-effectiveness. However, the further development of AMIBs has been impeded by their short cycling lifespan, primarily caused by the aqueous corrosion of Mg anodes in water-containing electrolytes, which generates inorganic passivation layers (e.g., Mg(OH)2 and MgO) on the anode surface. To address this challenge, we propose a collaborative two-pronged approach, involving the adoption of a novel electrolyte system (saturated MgCl2 aqueous solution containing 25 vol % PEG, SMP-3) and the use of a Mg alloy anode. Electrochemical investigations suggest that the PEG molecules form hydrogen bonds with H2O molecules, effectively suppressing water activity and thereby enhancing anode stability. The assembled PTO/Mg alloy full cell exhibited a stable discharge plateau at 1.5 V with an initial discharge capacity of 176.24 mAh g–1 at 200 mA g–1. Remarkably, the cell demonstrated exceptional cycling stability, maintaining a capacity of 150 mAh g–1 after 300 cycles (85% capacity retention), with an average Coulombic efficiency approaching 100%. The results demonstrate the feasibility of stabilizing Mg alloy anodes through an interfacial engineering strategy based on a water-in-salt electrolyte design. This strategic approach provides a novel pathway for developing low-cost, high-performance AMIBs.

B(C 6 F 5 ) 3 ·H 2 O has been long recognized as a common Brønsted acid. The lack of X-ray crystal structure of B(C 6 F 5 ) 3 ·H 2 O with other substrates has greatly limited the development of a new catalytic mode. In this work, a complex of B(C 6 F 5 ) 3 ·H 2 O and amide 2-phenyl-3,4-dihydroisoquinolin-1( 2H )-one with hydrogen bonds and π-π interactions is characterized by X-ray diffraction. Such noncovalent interactions in solution also exist, as verified by NMR, UV-Vis absorption, and fluorescence emission measurements. Moreover, the mixture of amide 2-phenyl-3,4-dihydroisoquinolin-1( 2H )-one and B(C 6 F 5 ) 3 ·H 2 O, instead of other tested Brønsted acids, shows a tailing absorption band in the visible light region (400–450 nm). Based on the photoactive properties of the complex, a photoredox catalysis is developed to construct α -aminoamides under mild conditions.

Selective reduction of nitroaromatics containing reducible groups is of great significance and has attracted the attention in chemical synthesis. Here, a low-cost and easy to operate H 2 O/CO 2 acidic system combined with non-precious metal iron powder was used to prepare amino aromatics without affecting double or triple bond. Under optimized conditions (1 MPa CO 2 , 60°C, 2.5 h), the selectivity of 3-aminostyrene reached 99.4% at 99.2% conversion of 3-nitrostyrene. For the reduction of 4-nitrophenylacetylene (4-NPA) to 4-aminophenylacetylene (4-APA), the conversion of 4-NPA reached 99.5%, and the selectivity to 4-APA could reach 90.5% with 0.2 MPa CO 2 at 60°C in 8 h. The Fe/H 2 O/CO 2 system is also effective for the one-pot transformation including the reduction and hydration of 4-NPA to 4-aminoacetophenone with a high conversion (95.4%) and selectivity (97.7%). After the reaction is completed, the acidic system will self-neutralize by the release of CO 2 . The non-precious metal-acidic system is green, low-cost, and high selective for the reduction of nitroaromatics without affecting the easy reducible groups and the hydration of alkyne group.

Low-entropy BaZr 0 . 1 Ce 0 . 9 O 3-δ ( Δ S c o n f = 0.33 R) was used as the matrix to design and construct a series of medium-entropy electrolyte systems - BaZr 0 . 1 Sn 0 . 1 Ce 0 . 6 X 0 . 2 O 3-δ ( Δ S c o n f = 1.09 R)-via co-doping with Sn 4+ and rare-earth ions (X = Dy, Nd, Yb, Y). By combining experimental characterizations with first-principles calculations (DFT), the effects of different rare-earth dopants on the phase structure, chemical stability, and electrochemical performance of these electrolytes were systematically investigated. Among electrolytes, BaZr 0 . 1 Sn 0 . 1 Ce 0 . 6 Nd 0 . 2 O 3-δ (BZSCN) shows the most stable phase composition and microstructure after 3 h of boiling H 2 O treatment and 3 h of CO 2 treatment at 700 °C. It exhibits high conductivity (3.19 × 10 −2 S cm −1 ) in humid air at 700 °C, with relatively stable conductivities after H 2 O (1.80 × 10 −2 S cm −1 ) and CO 2 (2.49 × 10 −2 S cm −1 ) treatments under the same condition. According to the first-principles calculation, compared with other BaZr 0.1 Sn 0.1 Ce 0.6 X 0.2 O 3−δ (X = Dy, Yb, Y) electrolytes, BZSCN electrolyte exhibits elevated reaction energy barriers for H 2 O (5.12 eV) and CO 2 (0.28 eV), alongside reduced adsorption energies for H 2 O (−0.508 eV) and CO 2 (0.054 eV), collectively underpinning its enhanced chemical stability. BZSCN-based anode-supported cell demonstrates a maximum power output of 0.64 W cm −2 at 700 °C when operated with humidified H 2 .

The substantial energy consumption and high greenhouse gas emissions associated with steam cracking have driven the exploration of alternative methods for producing light olefins from naphtha. In this context, we propose a novel strategy that integrates dehydrogenation cracking with selective hydrogen combustion to enhance naphtha cracking. This approach synergizes two key processes: the carbenium ion pathway for dehydrogenation and cracking, and the radical cracking mechanism. Together, they enable the production of light olefins (C 2 = –C 3 = ) with unprecedented efficiency. Atom-planting introduces SnO x into the H-ZSM-5 surface and framework, providing favorable dehydrogenation active sites to promote the dehydrogenation cracking of n-octane. The loading of La and Mn onto Sn-ZSM-5 results in the formation of a LaMnO 3 perovskite structure, which promotes the selective combustion of hydrogen generated from Sn sites to produce H 2 O. Following the loading of Na 2 WO 4 , the generated H 2 O is triggered to form hydroxyl radicals, which subsequently induce the free radical cracking of n-octane. The Na 2 WO 4 /La-Mn/Sn-ZSM-5 system integrates the advantages of Sn-ZSM-5 and perovskite, enabling simultaneous dehydrogenation cracking and selective hydrogen combustion. Moreover, combined with the Na 2 WO 4 - promoted H 2 O - induced radical cracking, the system exhibits exceptional n-octane conversion and olefin production capacity.

The practical application of aqueous Zn-ion batteries (AZIBs) is hindered by Zn dendrites, hydrogen evolution reaction (HER), and corrosion/passivation of Zn anodes. Herein, a Zn-philic Cu layer is first fabricated on Zn anodes, which not only physically covers scratches and fills defects on Zn anodes but also utilizes the high zincophilicity of Cu to guide uniform Zn deposition. A densely packed Zn 5 (OH) 8 Cl 2 ·H 2 O nanosheets (nZCH) layer is formed on Cu layer, which not only selectively adsorbs H 2 O and repels SO 4 2− to inhibit corrosion/passivation but also prevents electron leakage during Zn deposition in inner Cu layer due to the insulating nature to electrons, thereby suppressing HER. As a result, nZCH-Cu@Zn||nZCH-Cu@Zn symmetric batteries achieve ultra-stable cycling for over 4800 h at 1 mA cm −2 and 3600 h at 5 mA cm −2 . It should be emphasized that both Cu layer and nZCH layer constructed in this paper are obtained through a simple and low-cost one-step in-situ configuration strategy. The three-dimensional structure of nZCH facilitates electrolyte diffusion, ensuring uniform distribution of Zn 2+ concentration and electric field. Moreover, nZCH is a genuine passivation layer with a dense structure. Its presence inhibits the formation of loose pseudo-passivation Zn 4 SO 4 (OH) 6 ·xH 2 O layer, solving the long-standing passivation problem on Zn anodes. The top hydrophilic nZCH layer facilitates Zn 2+ de-solvation, repels SO 4 2− , and adsorbs H 2 O to suppress side reactions, while the bottom Zn-philic Cu layer provides abundant nucleation sites for dendrite-free Zn deposition.

Industrial fly ash-derived SiO 2 aerogel with abundant mesopores has an excellent ability to support active ingredients for constructing efficient and stable catalyst in electrochemical CO 2 reduction reaction (CO 2 RR). However, how to select and arrange active sites on its surface poses significant challenges due to its non-conductive nature. Here, we subtly designed and synthesized multi-component architectures to achieve the high efficiency of CO 2 RR to CO. The embedding of active and amorphous nitrogen-doped carbon (NC) nanosheets on the surface and inside of SiO 2 aerogel ensures the charge transport on the catalyst surface, and Er 2 O 3 improves dissociation of H 2 O, enabling the supply of protons for CO 2 RR. Simultaneously, Er 2 O 3 -induced defects/vacancies, nanoclusters coordinated with N on amorphous NC and single Ni in NC play crucial role in enhancing adsorption and activation of CO 2 . Consequently, the Ni-Er 2 O 3 /NC-SiO 2 catalyst exhibits the maintenance of FE CO higher than 95 % over a wide potential window (−0.22 to −1.12 V vs. RHE) in a flow cell with gas-liquid-solid electrode. This work not only provides an atomistic understanding of nature of active sites in CO 2 RR but also contributes to the secondary utilization of industrial fly ash for a carbon-neutral future.

Recently, halide perovskites (HPs) are considered as rising star materials for humidity sensing beyond their wide applications in the field of optoelectronics. However, the structural instability and toxicity of lead have always limited the application and development of HP materials in electronic devices. In this study, all-inorganic lead-free halide perovskite Cs 2 InCl 5 ·H 2 O (CICH-1) was synthesized by a facile precipitation method at room temperature. Compared with the sample via a harsh hydrothermal method (CICH-2), the CICH-1 perovskite in this work exhibits higher defect density, which brings significant advantages for humidity sensing. In the relative humidity (RH) range of 33%–97%, CICH-1 exhibits good linearity (Adj. R 2 = 0.99), high response (9.1 × 10 3 ), fast response (3 s), small hysteresis (0.89% RH), as well as excellent repeatability and long-term stability. This fine humidity sensing performance enables real-time non-contact monitoring of human finger and breath moisture changes with rapid response-recovery behaviors. This contribution provides a favourable candidate material for humidity detection, and opens up new possibilities for the application of all-inorganic lead-free HPs in sensory devices and further human healthcare.

Proteases, such as trypsin, are essential for extracting collagen in various industrial applications. The potential applications of rare earth nanomaterials, specifically yttrium nanoparticles, have attracted significant interest across various fields due to their distinctive characteristics, including high dielectric constant and thermal stability. Biomineralization has emerged as a promising approach to synthesize protein-inorganic nanomaterials with hierarchical structures and desired functions. In the present investigation, a novel protease-templated biomineralization strategy was developed for synthesizing protease-(NH 4 ) 2 Y 3 F 11 •H 2 O hybrid nanomaterials using a one-pot method under very mild conditions. For modifying the morphologies of (NH 4 ) 2 Y 3 F 11 •H 2 O throughout biomineralization, protease has been demonstrated to be a highly promising biotemplate. Protease was utilized as a template for morphological control in the biomineralization procedure, which resulted in a gradual transformation of the initially formed (NH 4 ) 2 Y 3 F 11 •H 2 O octahedral structures into uniform nanospheres. The applicability of this approach was supported by successfully utilizing various proteases to synthesize protease-(NH 4 ) 2 Y 3 F 11 •H 2 O hybrid nanospheres. In addition to a strong and desirable luminescent signal, these hybrid nanospheres demonstrated extensive recycling because of their high enzymatic activity, stability and durability. The protease-mediated biomineralization approach offers an easy and robust approach to develop innovative protease-inorganic composites. Its moderate reaction conditions and simple operation render it a viable tool for developing stable and reusable enzyme reactors in various industrial applications. Graphical Abstract

Boron-containing brines are widely distributed in nature, and within the pH range of salt lakes, B4O72– is one of the primary boron forms. To express the brine properties and phase equilibrium behavior of boron-containing brine systems, experiments and thermodynamic research based on the eNRTL framework were carried out. Tetraborate aqueous systems are focused in this study: (1) the phase diagram data of K2B4O7–K2SO4–H2O and K2B4O7–K2SO4–KCl–H2O systems at 298.15 and 323.15 K were experimentally determined; (2) the heat capacity of the B4O72– ion was determined via simultaneously fitting the thermodynamic property and solubility data of Li2B4O7, Na2B4O7 and K2B4O7 aqueous systems; (3) the liquid parameters (interaction parameters between water–ionic pair and ionic pair–ionic pair) and solid parameters (ΔfGk°, ΔfHk°, ΔCp,k°) for three binary systems (Li2B4O7–H2O, Na2B4O7–H2O, K2B4O7–H2O) and two ternary systems (K2B4O7–K2SO4–H2O, K2B4O7–KCl–H2O) were determined by fitting the multitemperature phase diagram data; and (4) the complete structures of the phase diagram for the ternary and quaternary systems were predicted. The results demonstrate that (1) the models can effectively describe the solution properties and solid–liquid phase equilibrium behavior of tetraborate-containing aqueous systems, (2) the parameters exhibit thermodynamic consistency, and (3) the predicted complete phase diagram is reasonable.

Bimetallic catalysts Pt–M/Ti were prepared by introducing various dopants (M = Mn, Fe, Co, Cu, Ce, Mo) into Pt/Ti with ultralow loadings (0.5 wt % M) and compared in CO oxidation in the presence of H2O and SO2. Among these catalysts, Pt–0.5Mn/Ti contributed the highest oxidation efficiency and strongest sulfur resistance. Further improvement of Mn contents led to the decrease of CO conversion. It was indicated that the introduction of appropriate Mn species enhanced the active oxygen supplying ability of the catalyst, thus improving the reaction activity. The CO oxidation performance of the catalyst was improved through the reaction between *OH from H2O dissociation and CO. The deposition of S on the Pt–0.5Mn/Ti surface did not increase with time extension. Theoretical calculation results revealed that cleavage of S–O–Mn species could be facilitated by Pt, and the SO2 adsorption energy calculations demonstrated that SO2 was more easily adsorbed on Pt/Ti than Pt–0.5Mn/Ti, which was very consistent with its sulfur resistance. In situ DRIFT studies at 260 °C revealed that the introduction of SO2 onto Pt–0.5Mn/Ti showed little change for CO adsorption on different Pt species, while Pt/Ti showed an apparent decrease of Pt0–CO. 18O isotopic experiments in the presence of H218O and SO2 were systematically designed to accurately quantify the CO2 composition including C16O16O, C16O18O, and C18O18O. Accordingly, the reaction mechanism for Pt–0.5Mn/Ti catalyzed CO oxidation consisting of four pathways was proposed.
