Previous studies on the preparation of ZnSnO 3 under normal pressure and non-epitaxy conditions are ambiguous and contradictory. Therefore, the phase evolution in preparing ZnSnO 3 powder with different calcination temperatures was systematically studied by precipitation method under normal pressure in the present work. The phase of the samples was characterized by XRD and Raman spectroscopy. Due to lacking the reliable Raman data of ZnSnO 3 in previous literatures, the Raman spectra of ZnSnO 3 with LiNbO 3 -type structure and ilmenite-type structure were simulated by first principle based on CASTEP module of Materials Studio. Moreover, the TG-DSC analysis was carried out for the as-dried precursor powder to further clarify the phase evolution. The results indicated that the phase of the as-dried precursor powder was ZnSn(OH) 6 with cubic structure and a series of decomposition reactions occurred with increasing calcination temperature. Wherein, ZnSn(OH) 6 began to decompose into ZnSnO 3 at about 170 °C, and then ZnSnO 3 began to decompose into Zn 2 SnO 4 and SnO 2 at about 320 °C. Namely, the thermal stability temperature of ZnSnO 3 should be lower than 320 °C under normal pressure. Furthermore, the beginning crystallization temperature for the decomposition-achieved Zn 2 SnO 4 and SnO 2 was about 670 °C. In addition, the morphologies of all the samples were detected by SEM, and mainly determined by the crystal structures of the phases in the samples.

Here, Ce-ZnSnO 3 nanocubes were synthesized via a simple one-step hydrothermal method. The gas-sensing performance toward acetone was investigated in terms of response, optimum operating temperature, response-recovery time and selectivity. The as-prepared 1% Ce-ZnSnO 3 nanocubes exhibit a high response of up to 215 toward 100 ppm acetone, with excellent selectivity toward acetone over other reducing gases, and also deliver outstanding response even under high humidity conditions. At 260 °C, this sample shows a fast response time of 2 s and recovery time of 1 s, while its optimum operating temperature is reduced by 40 °C. This study validates an effective strategy for enhancing the gas-sensing performance of ZnSnO 3 -based sensors through Ce modification.

In this paper, a series of Eu-doped ZnSnO 3 nanoblocks are prepared through one-step hydrothermal method. The structure and morphology of Eu-ZnSnO 3 nanoblocks are characterised using SEM,XRD, XPS and TEM tests. The gas-sensitive properties of Eu-ZnSnO 3 nanoblocks towards isopropanol are explored. Compared with pure ZnSnO 3 , the response of 4 % Eu-ZnSnO 3 sensor is enhanced nearly three times. The response recovery time was greatly improved by Eu doping, and the 4 % Eu-ZnSnO 3 sensor showed a recovery time of only 8/10s for 100 ppm isopropanol at 260 °C, which is a 2.9-fold reduction in recovery time. The catalytic effect of Eu and n-n heterojunction structure of Eu 2 O 3 -ZnSnO 3 all contribute to enhance the gas response. The results prove that the Eu-ZnSnO 3 nanoblocks have great potential for the detection of isopropanol.

ZnSnO3 is an attractive anode material for lithium ion batteries because of its higher theoretical capacity compared to the state-of-the-art carbonaceous counterpart. The main challenges associated with ZnSnO3 anodes are structural degradation and instability of the solid-electrolyte interphase, caused by the large volume change during cycling. Herein, we propose a hierarchical structured ZnSnO3@TiO2 nanocomposite anode that tackles this problem. The as-prepared, core–shell, cube-like anode material exhibits enhanced capacity and cycling property. In proof-of-concept experiments, this hierarchical heterostructure shows a high initial discharge capacity of 1590 mA h g−1 at 100 mA g−1 and retained 780 mA h g−1 after 200 cycles, which is much better than the anodes made of pure ZnSnO3 nanomaterials. The enhanced cycle life can be attributed to the reductive volume expansion during the repeated charge–discharge cycles, owing to the hierarchical porous three-dimensional structure and TiO2 shell as well as the synergistic effects of ZnSnO3 and TiO2.

A composite of cheap metallic Bi-decorated ZnSnO 3 was synthesized via a solvothermal method and applied for photocatalytic N 2 fixation for the first time. The results demonstrated that the Bi/ZnSnO 3 composite with 1.5 % Bi exhibited superior photocatalytic performance. with the optimal sample producing NH 3 at a rate of 988 μmol/L g -1 h −1 under simulated sunlight. This is 5 times faster than that of pure ZnSnO 3 . Additionally, the Bi/ZnSnO 3 composite showed significantly better photocatalytic performance than pure ZnSnO 3 in RhB degradation. Structural analyses confirmed successful loading of Bi nanoparticles on the surface of ZnSnO 3 . Furthermore, diffuse reflectance spectroscopy analysis revealed that the surface plasmon resonance effect of metal Bi effectively improved the optical absorption performance. However, the sensitization of metal Bi had a limited contribution to the high photocatalytic activity of the Bi/ZnSnO 3 . Electrochemical analyses indicated that the Schottky barrier formed between Bi and ZnSnO 3 captured photo-generated electrons and promoted the charge separation, which was considered responsible for the increased photoactivity of Bi/ZnSnO 3 .This work provides a new application of Bi/ZnSnO 3 and may offer new ideas for the application of ZnSnO 3 materials in the field of photocatalysis, which are crucial for addressing environmental pollution and energy conversion challenges.

A series of hierarchical N, S co-doped ZnSnO 3 /Zn 2 SnO 4 porous hollow octahedrons (NS/ZnSnO 3 /Zn 2 SnO 4 ) were constructed using the strategy of combining acid-etching technique with in-situ decoration method for the removal of various pollutants in aqueous environment. The optimized NS/ZnSnO 3 /Zn 2 SnO 4 exhibited an enhanced photocatalytic activity under simulated sunlight, removing heavy metal ion Cr(VI) in 140 min and rhodamine B (RhB) in 50 min, outperforming hollow Zn 2 SnO 4 and ZnSnO 3 /Zn 2 SnO 4 octahedrons. This raise could be attributed to the synergetic effect of ZnSnO 3 /Zn 2 SnO 4 heterojunctions, the introduction of N, S elements and unique hierarchical porous hollow morphology. In addition, the photocatalytic activities of NS/ZnSnO 3 /Zn 2 SnO 4 for removing Cr(VI) and RhB from mixed pollutant solutions were 1.94 and 1.53-folds as high as those of single system, and it also displayed good reusability and stability in co-existing system, suggesting its potential practical applications in the simultaneous removal of various pollutants from contaminated water.

This work designs a competitive consumption strategy of surface electron donor and light absorption for quenching the photocurrent of ZnSnO 3 nanocubes/BiOI nanoarrays/polydopamine (ZnSnO 3 NCs/BiOI NAs/PDA) as a photoactive material. This material can be formed on electrode surface by successive coating and deposition to provide a substrate for immobilization of capture antibody, and producing strong photocurrent in the presence of ascorbate acid as a surface electron donor due to the well matching structure of band gaps between ZnSnO 3 NCs and BiOI NAs, the excellent light absorption ability and high photo-electron conversion efficiency of BiOI NAs and PDA, and the accelerated electron transfer . Using ascorbate oxidase loaded dopamine-melanin nanosphere (DAM-AAO) as a label of the signal (secondary) antibody, the sandwich-type immunoreaction leads to dual photocurrent quenching of the label through the competitive consumption of ascorbate acid with enzymatic oxidation and the light absorption by DAM nanosphere. Thus, a sensitive “On-Off” photoelectrochemical (PEC) immunosensing method is constructed for the analysis of neuron specific enolase (NSE). The proposed method shows a detection range of 0.1 pg/mL −50 ng/mL and a detection limit of 0.03 pg/mL. The excellent performance and the recovery text demonstrated the practicability of the designed strategy and label in immunoassay of different protein biomarkers.

In this work, hollow double-shelled ZnSnO 3 /SnO 2 heterojunctions are fabricated via a straightforward self-sacrificing template route. The crystal structure, microstructure, elemental composition, surface chemical states, optical properties and oxygen vacancies of the as-prepared materials are systematically characterized. Gas sensing tests reveal that the ZnSnO 3 /SnO 2 -2 sample exhibits a high response of 104.5 toward 100 ppm triethylamine (TEA) with a rapid response speed of 1 s at a relatively low operating temperature of 160°C, along with good selectivity, repeatability and long-term stability. The enhanced gas sensing mechanism is elucidated from the perspectives of electronic structure and surface reaction by combining density functional theory (DFT) calculations and in-situ Fourier transform infrared (FTIR) spectroscopy. Furthermore, preliminary monitoring of pork freshness during storage using the ZnSnO 3 /SnO 2 -2 sample demonstrates its potential in practical applications. This study provides a theoretical foundation and experimental support for the design of high-performance and low-power TEA gas sensors.
