Hydrogen energy is a highly promising clean energy source, held immense potential for commercial applications. However, the inherent flammability of hydrogen posed significant safety challenges, creating an urgent need for the development of reliable, standalone, and cost-effective hydrogen sensors. Currently, main hydrogen sensors typically relied on high-temperature operating conditions, which to some extent limited their deployment in specific application scenarios. Our research focused on material systems and structural design. Hollow spherical ZnSnO 3 nanoparticles were first synthesized, followed by uniform loading of ZnSnO 3 onto rGO aerogel to form a p-n heterojunction. Notably, the ZTO@rGA-4 sensor exhibited a high response value (98.2) to 10,000 ppm hydrogen at 25 °C, with short response/recovery time (44/92 s), alongside excellent repeatability and long-term stability.

N-butanol is a volatile organic compound (VOC) that is harmful to human health, and the development of gas sensors for n-butanol vapor detection is necessary. In this work, the nanoflowers-like ZnSnO 3 was synthesized via a one-step hydrothermal route followed by an annealing process. The results revealed that optimizing the hydrothermal time to 12 h resulted in ZnSnO 3 -2 exhibiting the highest gas response (40.48) towards 100 ppm n-butanol at 275°C, boasting a detection limit of 500 ppb. Furthermore, ZnSnO 3 -2 exhibits excellent gas selectivity and long-term stability. The improved sensing performance of ZnSnO 3 -2 was attributed to its large specific surface area and abundant oxygen vacancies. Additionally, the gas sensing mechanism for enhancing n-butanol detection was comprehensively analyzed. These results highlight the potential of nanoflower-like ZnSnO 3 as a promising candidate for n-butanol gas sensing material, offering both high sensitivity and selectivity. Moreover, this research provides valuable guidance for the development and optimization of gas sensing materials for applications in environmental monitoring and industrial safety.

Fabricating heterophase junctions proves to be an efficient strategy for achieving efficient charge separation and enhancing the catalytic activity of photocatalysts. Surprisingly, this approach is rarely utilized in the field of piezocatalysis. In this work, a novel ZnSnO 3 heterophase junction catalyst was fabricated by combining rhombohedral (R-ZnSnO 3 ) and orthorhombic (O-ZnSnO 3 ) phases for efficient piezo and piezo-photocatalytic RhB degradation and N 2 fixation. The piezocatalytic RhB degradation rates of ZnSnO 3 heterophase catalysts are 5.6 and 3.6 times higher than those of O-ZnSnO 3 and R-ZnSnO 3 , respectively, with similar enhancements observed in piezocatalytic N 2 fixation. The coupling of R-ZnSnO 3 and O-ZnSnO 3 does not increase the piezoelectric properties; however, an S-scheme structure formed at the interface. Under the combined effects of band bending, interface electric fields, and Coulomb attraction, electrons and holes migrate and achieve effective spatial separation. This result supports the energy band theory over the induction charge theory, contributing to the ongoing debate in piezocatalytic mechanisms. Electrochemical analyses and piezo-photocatalytic tests further indicate that ZnSnO 3 heterophase junctions exhibit a synergistic effect between piezocatalysis and photocatalysis. This synergy can be attributed to the complementary effects of photoinduced carrier generation and piezoelectric field-assisted carrier separation. Hydroxyl radicals, superoxide radicals, and holes serve as the primary active species responsible for piezocatalytic RhB degradation through a mechanism similar to photocatalysis. Theoretical calculations reveal that the Sn site on the surface of O-ZnSnO 3 acts as the active site within the ZnSnO 3 heterophase junction, providing valuable insights for future catalyst development. This work offers a deeper understanding of the synergistic mechanisms in piezo-photocatalysis, presenting a promising route for efficient environmental and energy applications.

Morphology control and noble-metal modification have become effective ways to improve the gas sensing performances of mixed-metal-oxide sensors. In this study, ZnSnO3 nanocube structures with different morphologies were synthesized via combining NaOH-assisted dissolution and a calcination process, and they were then modified with various amounts of Au nanoparticles through a chemical reduction method. Some important parameters were systematically investigated to optimize the gas sensing performance toward toluene detection. Noticeably, the as-prepared Au2NPs@ZnSnO3 hollow nanocube sensor exhibits an ultra-high response (80.82@100 ppm), fast response and recovery times (11 s/12 s, respectively), a low limit of detection (10 ppb), excellent repeatability, long-term stability, and good anti-humidity properties. The enhanced gas sensing mechanism of the Au2NPs@ZnSnO3 sensor is also thoroughly discussed, which can be attributed to the unique hollow nanocube structure and the excellent electron sensitization and chemical sensitization properties of AuNPs. As a result, the optimum AuNP-modified ZnSnO3 sensing material is promising for high-sensitivity toluene detection for practical applications.

With the development of spintronics, ferromagnetic nanomaterials have shown unique advantages in the fields of information storage and quantum computation. The ABO3-type perovskite oxide ZnSnO3 is expected to realize d0 ferromagnetism due to its tunable crystal structure and unique electron arrangement. In this work, for the first time, the inhomogeneous oxygen octahedral structural distortion along the c-axis induced by SC CO2 can be found in 2D ZnSnO3, i.e., distortion of ZnO6 is larger than that of SnO6, and they are served as the structural basis for the generation of room-temperature ferromagnetism. In addition, combining the change in the concentration of the oxygen vacancies to ultimately realize the room-temperature d0 ferromagnetism in ZnSnO3 (Tc = 400 K, Ms = 0.1123 emu/g) can be presented. Therefore, this study establishes a new strategy for the development of transition metal-free ferromagnetic materials for the application of spintronic devices at room temperature.

Uniform and monodisperse ZnSnO3 cubic crystallites were prepared via a solution process involving the reaction of zinc sulfate and sodium stannate at a reaction temperature as low as 0 °C without any surfactant. The size was readily controlled from 40 to 600 nm by varying the reaction temperature. The possible formation mechanism of cubic crystallites was attributed to a nucleation assembly process. The as-fabricated sensors based on ZnSnO3 cubic crystallites showed high sensitivity, fast response, and short recovery times toward HCHO gas. And as the particle-size of ZnSnO3 cubic crystallites decrease, the sensitivity of gas sensors based on them increases and the recovery time shorten rapidly. The detection limit of ZnSnO3 cubic crystallites sensor can reach as little as lower than one per million for HCHO. The performance of a home-built ZnSnO3 cubic crystallites sensor was even better than the competing SnO2 and In2O3 sensor, making this material interesting for sensor devices.

In this paper, Au nanoparticles (AuNPs) loaded ZrO 2 /ZnSnO 3 nanocubes are prepared through hydrothermal route and chemical reduction method. The crystal structure, morphology, element distribution, chemical composition, specific surface area and pore size of ZrO 2 /ZnSnO 3 nanocubes are described with XRD, TEM, XPS and BET. Interestingly, the incorporation of Zr ions induces the fragmentation of the edge of ZnSnO 3 nanocubes, which enhance specific surface area of ZrO 2 /ZnSnO 3 nanocubes. The response of ZnSnO 3 materials for isopropanol is increased through doping ZrO 2 and modifying AuNPs. The 1.5 at% AuNPs-loaded 5 at% ZrO 2 /ZnSnO 3 nanocubes presents a higher response to 100 ppm isopropanol with a fast response/recovery time (3/4 s) at the operating temperature of 260℃. And the generation of ZnSnO 3 , ZrO 2 and AuNPs heterojunctions contributes to raise the isopropanol response. In addition, the catalysis of ZrO 2 and AuNPs also can increase their reaction speed between absorbed oxygen and isopropanol molecules. This research results provide a new scheme for the development of isopropanol sensor.

Multi-shelled hollow structures have been drawing wide attention in various fields because of their large surface area , short diffusion path and less agglomerated configuration. Herein, ZnSnO 3 hollow microspheres with controllable shell numbers have been prepared by a facile solvothermal reaction and following annealing treatment. The test results show that multi-shelled ZnSnO 3 hollow microspheres exhibit excellent acetone sensing performance, which is superior than that of double-shelled samples. In particular, multi-shelled ZnSnO 3 hollow microspheres not only show high responses of 105.1 and rapid response/recovery speed (1/18 s) to 100 ppm acetone, but also exhibit good repeatability, long-term stability and anti-humidity properties. Furthermore, they can easily distinguish healthy breath from simulated diabetic breath. And they still show rapid response/recovery speed in actual breath detection, which is beneficial to the achievement of real-time detection. The enhanced sensing performance has been studied systematically. Thus, multi-shelled ZnSnO 3 hollow microspheres have a great potential for the diagnosis of diabetes.

Hierarchical ZnSnO3/Zn2SnO4porous hollow octahedrons were constructed using the method of combining the acid etching process with the in situ decoration technique for photovoltaic and photocatalytic applications. The composite was used as photoanode of the dye-sensitized solar cells (DSSCs), an overall 4.31% photovoltaic conversion efficiency was obtained, nearly a 73.1% improvement over the DSSCs that used Zn2SnO4solid octahedrons. The composite was also determined to be a high-performance photocatalyst for the removal of heavy metal ion Cr (VI) and antibiotic ciprofloxacin (CIP) in single and co-existing systems under simulated sunlight irradiation. It was remarkable that the composite displayed good reusability and stability in a co-existing system, and the simultaneous removal performance could be restored by a simple acid treatment. These improvements of solar energy utilization were ascribed to the synergetic effect of the hierarchical porous hollow morphology, the introduction of ZnSnO3nanosheets, and the heterojunction formed between ZnSnO3and Zn2SnO4, which could improve light harvesting capacity, expedite electron transport and charge-separation efficiencies.Keywords:ZnSnO3/Zn2SnO4;hierarchical hollow octahedron;dye-sensitized solar cells;simultaneous removal;photocatalytic activity

Through the interface regulation of surfactant, using the hydrothermal method to deposit 0D ZnSnO 3 on the surface of 3D CuBi 2 O 4 , the S-scheme ZnSnO 3 -CuBi 2 O 4 (ZSCB) heterojunction photocatalyst was synthesized, which exhibits outstanding redox capabilities. The strong light absorption performance of CBO in the visible range promotes its excellent photothermal conversion ability under visible light. Under visible light irradiation, its surface temperature can be increased from 26.2℃ to 98.5℃ within 9 minutes. Images at 808 nm near-infrared radiation show that the S-scheme ZSCB heterojunction can convert 34.16 % of light energy into heat energy in aqueous solution. Due to the S-scheme charge transport mechanism and photothermal effect of ZSCB, the heterojunction had excellent photogenerated carrier separation efficiency and high redox capacity, which can degrade 85.4 % of TC within 90 minutes, and the degradation rate was 3.1 times that of monomer CBO, also excellent TC degradation performance in simulated natural water and different ionic. The Fukui index and the change of mass charge ratio of TC during the degradation process, predicting the attack site of TC at the atomic level and clarifying that the S-scheme ZSCB heterojunction was controlled by electrophilicity, nucleophile and free radical during the photothermal photocatalytic degradation of TC. The ecological structural activity relationship model and mung bean culture experiment revealed the low ecological risk of TC degradation from theory to practice. This study provides a novel approach to the degradation of emerging pollutants and the environmental toxicology research associated with S-scheme heterojunctions.

The photoactivity of CdS nanorods was greatly improved by amino functionalized accordion-like MXene and spherical ZnSnO 3 . MXene possesses good electron transfer capability and ZnSnO 3 presents matched energy band with CdS, which deeply accelerate the electron transfer and prevent the recombination of photogenerated electron-hole pair, leading to a strong photoelectrochemical (PEC) response. Taking the merit of the improved photoactivity of CdS nanorods, a novel PEC biosensor was constructed for DNA hydromethylation detection based on immune recognition of target molecule, where 5-hydroxymethyl-2′-deoxycytidine triphosphate (5hmdCTP) was employed as detect target, CdS/MXene was used as photoactive material, and ZnSnO 3 was adopted as signal amplification unit. Under enzymatic covalent reaction of –CH 2 OH of 5hmdCTP with –NH 2 of MXene, 5hmdCTP was specifically recognized and captured. Then, taking advantages of the covalent reaction between phosphate group of 5hmdCTP and ZnSnO 3 , the signal amplification unit was captured. Under the optimum conditions, this PEC biosensor presents wide linear range of 0.008–100 nM and low detection limit of 4.21 pM (3σ). The applicability of the developed method was evaluated by investigating the effect of Cd 2+ and perfluorohexane compound pollutant on 5-hydroxymethylcytosine content in the genomic DNA of the roots and leaves of wheat seedlings.

The research on the synthesis of three-dimensional (3D) porous structures has garnered significant interest among scholars. In this study, ZnSnO 3 /ZnO heterostructures are prepared using butterfly wings as biotemplates, resulting in the formation of a hierarchical porous network structure characterized by regular ridges and pillars. Subsequently, we construct a resistive gas sensor utilizing these ZnSnO 3 /ZnO heterostructures, which exhibits not only a relatively high responses (14.7) but also rapid response and recovery speed (1 s/6 s) when exposed to 100 ppm n-propanol at 220 °C. Furthermore, the sensor demonstrates a low limit of detection (LOD) of 432 ppb, strong repeatability, good long-term stability (80 days), and excellent anti-humidity properties (S 84 % /S 33 % ≈ 0.84). The enhanced gas sensing performance is primarily attributed to the formation of ZnSnO 3 /ZnO n-n heterostructures, the increase in oxygen vacancies, and the presence of ordered open porous structures. Consequently, ZnSnO 3 /ZnO heterostructures show significant potential for the detection of n-propanol gas in practical applications. This work also presents a promising strategy for the development of homogeneous/heterogeneous materials with a 3D open porous structure, which can be applied in surface-related fields.
