The interface compatibility lies in the heart of present investigations on solid-state batteries, now facing significant challenges in practical use. The non-coherent interface structure with the underlying complex electrochemical processes evolves dynamically to pregnant the unfriend seeds to degrade the battery performance. Therefore, interface engineering (or control) in solid-state batteries gives birth to a new theme as ‘the interface is equal to the battery’. In this context, a facile but robust technique is proposed here by smoothing the Li 1.5 Al 0.5 Ge 1.5 P 3 O 12 (LAGP) ceramic pellet with a mirror-like surface, which is found operational in running a solid battery in unprecedentedly a thousand cycles with capacity retention of 80% at 0.5C, 50 °C. Such an unconventional operation is, as a matter of fact, largely decreasing the physically interface contact but proved powerful in guiding the Li-ion homogeneous deposition. Moreover, the self-generated LiF involved interphase layer works efficiently to dynamically balance structural and electrochemical stabilities, where the LiF is introduced by the in-situ polymerization of tiny liquid electrolytes. Hence, the profound results draw the incompatible interface issues forth to the component adjustment of interphases, namely in search for rational descriptions to connect the solid-state electrolyte and electrodes, which probably holds the key to unlocking the high energy density solid-state batteries.

The widespread application of epoxy resin (EP) is limited by its inherent high fire hazard, primarily attributed to its substantial release of heat and the generation of toxic byproducts during combustion. The usage of 2D material of titanium carbide (MXenes, defined as MX) has been confirmed to show potentials in flame retardation. However, the flame-retardant efficiency of MX is relatively-low. Thus, the interfacial engineering strategy is employed for in-situ development of MoS 2 nanoflakes on MX surface, acquiring the product of MX@MoS 2 , which shows the higher interfacial interaction with EP matrix and dispersion stability. By only using 1.0 wt% MX@MoS 2 , the PHRR and THR are obviously decreased by 35.8 % and 38.0 %, respectively. Notably, the addition of 3 % MX@MoS 2 results in a higher PHRR reduction 49.4 %. Meanwhile, the PSPR and TSP have reduced by 48.6 % and 36.9 %. Such results indicate the enhanced flame retardance, benefiting from the physical barrier and chemical catalyst roles of MX@MoS 2 . Of note, the peak CO and CO 2 yields are decreased by 53.3 % and 57.2 %. Upon exposure to heat source, MX@MoS 2 promotes the formation of dense, thermally-stable char layer, which effectively insulates the underlying polymer, slows down thermal and material transport, and impairs the volatile emissions. It is satisfying to find that the mechanical characteristics of EP composites are enhanced after adding MX@MoS₂. This study offers ideas to produce an extremely efficient MX-based flame retardant, extending the applications of composites made of polymers.

Designing and fabricating nanozymes with photoactivity for CO 2 reduction poses a significant challenge. Here, a hierarchically structured ZFs-tpyNi heterojunction nanozyme, comprising a terpyridine-based Ni complex supported on ZrO 2 nanoframes, has been created through an interfacial engineering strategy for efficient CO 2 reduction under visible light. Due to its unique structural and compositional advantages, ZFs-tpyNi demonstrates superior photocatalytic CO 2 -to-CO conversion compared to its counterpart of ZFs and tpyNi, achieving a CO yield of 18.2 µmol and a selectivity of 92.4 % with a high apparent quantum efficiency of 0.96 % in 3 h. These innovative catalysts also show excellent durability for at least eight cycles without a loss in performance, maintaining a remarkable structural stability with no obvious collapse of its framework and morphology. Systematic investigations reveal that ZFs-tpyNi heterostructures exhibit a high specific surface area advantageous for the effective loading of tpyNi and exposure of active sites. The robust ZFs framework, characterized by extensive porosity, prevents nanoparticle agglomeration and accelerates mass transfer during catalysis. Additionally, the spatially heterogeneous interface enables precise modulation of band alignment and bandgap dynamics in nanozymes, enhancing light absorption and promoting the generation and separation of photogenerated charge carriers. Consequently, the nanozyme demonstrates enhanced CO 2 adsorption and activation capabilities, leading to improved selectivity of catalytic products. This work aims at highlight the role of nanozyme catalysts in sustainable energy production.

With the increasing demand for dielectric materials in high-frequency microwave applications, fluoropolymer-based dielectric materials have been widely utilized due to their excellent dielectric and insulation properties. However, the low thermal conductivity limits their ability to meet the thermal dissipation requirements during high-frequency and high-speed signal transmission. The present study introduces a pioneering interface engineering strategy wherein C–F bonds on the surface of ethylene-tetrafluoroethylene copolymer (ETFE) are photo-catalytically activated, enabling successful grafting of poly(glycidyl methacrylate) (PGMA) chain segments. Subsequently, the resulting graft copolymers are blended with thermally conductive h-BN filler to prepare composite dielectric materials. The results demonstrate that the incorporation of PGMA segments significantly enhances the interfacial compatibility between the ETFE matrix and h-BN filler, resulting in composites with a dense microstructure and outstanding dielectric and thermal properties. At a filler content of 30 vol%, the ETFE-g-PGMA@BN composite achieves an in-plane thermal conductivity of 4.2 W (m K)−1 and a through-plane thermal conductivity of 0.77 W (m K)−1. Moreover, at 1 GHz, the composite exhibits a dielectric constant of 2.2 and a dielectric loss of 0.004. This work presents a novel interface design strategy for surface modification of PTFE-based fluoropolymers, expanding their potential applications in printed circuit boards (PCBs) and providing a new direction for the design of polymer-based dielectric materials.

Interface engineering strategies passivate defects on the polycrystalline perovskite film surface and improve the stability of corresponding perovskite solar cells (PSCs). However, a single interface engineering step can result in restricted benefits on various occasions. Therefore, an appropriate additional modification step can be necessary to synergistically improve the device performance. In this study, a two-step interface engineering strategy is developed. Initially, the CsPbI3 perovskite surface is modified by choline iodide (ChI) to construct a 1D ChPbI3/3D CsPbI3 heterojunction, and then an additional surface modification step with the use of crown ether is applied. The crown ether modification can further eliminate unpassivated surface defects after heterojunction construction. Benefiting from the inhibited interfacial recombination, the resultant carbon-electrode-based CsPbI3 PSCs (C-PSCs) deliver a champion efficiency of 18.78%, representing one of the highest levels in this field. Besides, crown ether can synergistically improve the stability of the device against moisture, heat, and light stress due to the enhanced hydrophobicity and suppressed ion migration.

Heterojunction has been widely used in vibration-driven piezocatalysis for enhanced charges separation, while the weak interfaces seriously affect the efficiency during mechanical deformations due to prepared by traditional step-by-step methods. Herein, the intimate contact interfaces with shared S atoms are ingeniously constructed in SnS 2 /SnS anchored on porous carbon by effective interface engineering, which is in-situ derived from temperature-dependent self-transformation of SnS 2 . Benefiting from intimate contact interfaces, the piezoelectricity is remarkably improved due to the larger interfacial dipole moment caused by uneven distribution of charges. Importantly, vibration-induced piezoelectric polarization field strengthens the interfacial electric field to further promote the separation and migration of charges. The dynamic charges then transfer in porous carbon with high conductivity and adsorption for significantly improved piezocatalytic activity. The degradation efficiency of bisphenol A (BPA) is 6.3 times higher than SnS 2 and H 2 evolution rate is increased by 3.8 times. Compared with SnS 2 /SnS prepared by two-step solvothermal method, the degradation efficiency of BPA and H 2 evolution activity are increased by 3 and 2 times, respectively. It provides a theoretical guidance for developing various multiphase structural piezocatalyst with strong interface interactions to improve the piezocatalytic efficiency.

Heterostructure materials are increasingly utilized in solar energy conversion to pursue high efficiency and long-term stability. The charge transfer across interfaces gives rise to major energy loss arising from non-ideal interfacial effects, i.e., high interfacial energy barrier and low interfacial contacting area. Herein, we demonstrate a facile interface engineering strategy to eliminate non-ideal interfacial effects. A heterojunction of CN@C-P25 is constructed via polyphenol-assisted assembly of titania (P25) and carbon nitride (CN). The uniform dispersion of P25 on CN enlarges the interfacial contacting area of 3.2-fold compared with random dispersion, while the transformation of polyphenols into conjugated carbon facilitates the interfacial charge transfer by switching a 0.4 eV Schottky contact to a 0.1 eV Ohmic contact between CN and P25. A 2.5-fold enhancement of charge transfer flux is obtained with an initial reaction rate of 5185 μmol h −1 g −1 for photocatalytic nicotinamide regeneration.

Doping and interface engineering are both pivotal strategies for enhancing the selectivity of CO 2 reduction catalysts. However, as these strategies have often been explored independently, the question of which is more effective or whether their effects can be synergistically combined remains open. Given that doping and interfaces serve as crystallographic defects, they can be engineered to coexist within the same crystal structure. In this study, we strategically introduced both defects into a copper catalyst by modulating the indium content during crystal growth. Our investigation into the electrochemical performance of these catalysts for CO conversion reveals that while doping consistently enhances conversion selectivity, the presence of Cu/In interfaces disrupts this trend. The most promising catalyst, with 3% indium doping, demonstrated an impressive CO selectivity of 95.38±1.5% and a partial current density of -2.25 mA cm - ² at -0.8 V vs. Reversible Hydrogen Electrode (RHE). This research provides critical insights into the complex interplay between doping and interface engineering, offering a new pathway for the rational design of highly selective CO 2 reduction catalysts.

Electrocatalysts with the advantages of stability, high efficiency, and noble-metal-free features are in urgent need for water splitting. Herein, for the first time, based on the interface engineering, a novel BNNS@Ti3C2 intercalation electrocatalyst was prepared via a controllable synthesis strategy. The rich active sites of Ti3C2 were better protected as well as were able to serve as a bridge to connect the different layers of BNNS. Furthermore, combining the first-principles calculations, the nature of the interface proved the transformation from semiconducting properties to metallicity in this unique intercalation structure. The as-obtained composite possessed improved conductivity and abundant catalytic active sites, exhibiting a low onset potential of 23 mV and overpotential of 52 mV (vs. RHE) at 10 mA cm−2 with outstanding stability. BNNS@Ti3C2 was used as an electrocatalyst for the first time without noble-metal assistance. This study demonstrates that the layered materials can serve as a promising electrocatalyst by interfacing with the intercalation structure.

Abstract Interface engineering has been regarded as an effective strategy to manipulate the thermoelectric performance of materials. Here, we use a facile chemical electroless plating and a spark plasma sintering process to fabricate Ag-plated SnTe bulk. After sintering, a small amount of plated Ag can be doped into SnTe to suppress the Sn vacancies and the others form Ag precipitates with a size distribution from nanoscale to microscale, which introduces Ag/SnTe interfaces to enhance the Seebeck coefficient via energy filtering effect. Simultaneously, these structures result in strong scattering to reach a low lattice thermal conductivity of ~ 0.62 W·m –1 ·K –1 . Consequently, a maximum figure of merit ( zT ) of ~ 0.67 at 823 K is achieved in 2 wt% Ag-plated SnTe, which is ~ 60% higher than that of pristine SnTe. Moreover, the microhardness indentation test results show that the mean microhardness of 2 wt% Ag-plated SnTe is HV 64.26, which is much higher than that of pristine SnTe, indicating that Ag electroless plating can improve the mechanical properties of SnTe. This work has provided a facile and eco-friendly method to realize the interface engineering for manipulating the thermoelectric and mechanical properties of SnTe. Graphical abstract

Deliberately modulating the surface structure of oxide semiconductor materials was crucial to improve their photoelectronic conversion performance. Here, surface engineering of a Cu2O-based semiconductor (cubic particles in an average size of 300 nm) by redox embedding Rh with RhCl63– was attempted to get a series of Rh–Cu2O catalysts, and their photocatalytic properties were typically surveyed from dye (methyl orange, MO) photodegradation. With comprehensive characterizations, it was demonstrated that the highly dispersed and tightly integrated Rh–Cu2O interface, featuring oxidatively bonded Rh in surface layers of the Cu2O substrate, was well constructed by adjusting Rh loading from 0.04 to 0.38 wt %, exhibiting an obvious enhancement in photocatalytic performance for MO degradation compared to bare Cu2O. The measurements from photoproduction of H2, photocurrent, electrochemical impedance, and scavengers-present tests further illuminated that the Rh species bonded on the Cu2O surface in an electron-deficiency state and greatly contributed to not only improving separation efficiency of photogenerated electron/hole pairs, but also lowering the resistance to speed charge transferring along the Rh–Cu2O interface, resulting in the enhanced photocatalytic performance of Rh–Cu2O catalysts. In addition, the photocatalytic principle of Rh–Cu2O catalysts for dye degradation was also discussed. These results indicated that oxidatively bonded metal species in surface layers of Cu2O was feasible for getting an efficient charge-separation–transferring M–Cu2O interface to improve the photoelectronic conversion performance, which could be referred to as a notable system to directly engineer a semiconductor surface for advanced photoenergy applications.

CO 2 reduction by a sustainable pathway such as photothermal catalysis is highly demanded currently, high carrier recombination rate still severely limits the performance of photothermal catalysis. Constructing heterojunction interfaces with high exposed area is an effective strategy to solve the problem of carrier recombination. However, fine control of the interface structure is still highly challenging. Herein, Density functional theory (DFT) calculations were constructed to reveal that metallic Bi leads to more densities of states (DOS) generation at the conduction band edge in Bi-BiOBr, which argues that photogenerated electrons are more likely to be delivered to metallic Bi. A TiO 2 @Bi-BiOBr hollow hierarchical core–shell heterojunction was designed, providing a highly exposed interface and Bi between interfaces. Such structure endows the catalyst with excellent photothermal catalytic performance, achieving a CO yield of 30.4 μmol·h −1 ·g −1 . The highly improved performance is attributed to interfacial thermoelectrons transfer boosted by the construction of TiO 2 @BiOBr heterojunction as well as metal Bi. And a possible CO 2 reduction pathway is proposed, which is consistent with the Carbine pathway. This study provides an exciting idea for the modulation of photoelectron transfer at catalyst interfaces.
