Summary: With the rapid development of the industry, studies on environmental pollution, health, and safety are increasing. Gas sensors, with their promising characteristics of low cost, sensitivity, and portability, play a critical role in environmental monitoring, personal safety, and supervision of toxic gases. Flower-like metal oxide nanostructures, such as ZnO, SnO2, and In2O3, have been intensively studied to improve the sensing performances of gas sensors due to their increased surface area and material selectivity to gas molecules. Hydrothermal and sol-gel methods are the most preferred synthesis techniques for these nanostructures.

Summary: This study developed a ZnSnO3 based gas sensor for detecting pyridine in rice aging. The sensor, decorated with g-C3N4, showed high sensitivity, short response/recovery time, and low detection limit, attributed to the catalysis of g-C3N4 nanosheets, the decorated microstructure, and the formation of heterojunctions. Practical experiments demonstrated its higher sensitivity towards volatiles generated from Japonica rice aging compared to Indica rice and Polished Glutinous rice, suggesting its potential application in quality inspection of rice and other products.

Summary: Designing S-Scheme heterojunctions can effectively improve the photocatalytic performance for hydrogen evolution by avoiding futile charge transport routes. In this study, a twin S-Scheme heterojunction consisting of graphitic C3N4 nanosheets, hydrogen-doped rutile TiO2 nanorods, and anatase TiO2 nanoparticles was proposed. The catalyst exhibited a high hydrogen evolution rate of 62.37 mmol g(-1) h(-1) and an apparent quantum efficiency of 45.9% at 365 nm. The significant enhancement of photocatalytic performance was attributed to the efficient charge separation and transfer facilitated by the unique twin S-Scheme structure. In situ X-ray photoelectron spectroscopy (XPS), electron spin resonance (ESR) spin-trapping tests, and other characterizations confirmed the charge transfer route in the twin S-Scheme.
