Summary: In this study, In2O3/PANI composites were synthesized using the hydrothermal technique to explore their sensing capabilities for NO2 gas. The gas sensing properties, such as response/recovery time, optimal temperature, and recyclability, were investigated by analyzing the morphology, purity, and crystal structures of the samples. The In2O3/PANI-1 sensors exhibited high responses, quick response and recovery times, and a low detection limit to NO2 gas at a working temperature of 250 degrees C. The fundamental detecting mechanism for NO2 gas and the electrical characteristics of the In2O3/PANI composites were also discussed.

Summary: In this study, a novel SnO2 nanorod/spindle-like Fe2O3 heterostructure was successfully fabricated through a simple two-step hydrothermal route, which showed improved gas sensing performance on volatile organic compounds compared to pure Fe2O3. The enhanced gas-sensitivity performance of the hierarchical SnO2/Fe2O3 heterostructures can be attributed to the synergistic effect and heterojunction of the interface between spindle-like Fe2O3 and SnO2 nanorod. This research may provide new insight and a rational strategy for upgrading the sensing performance of certain semiconductor metal oxide materials through the design of novel layered nanostructures in the future.

Summary: In recent years, the introduction of other elements has been an effective method to improve gas sensing performances by generating oxygen vacancies. Cu-doped alpha-Fe2O3 porous spindles were successfully prepared using MIL-88-Fe as the precursor through a simple solvothermal method. The presence of Cu ions helps restrain the growth of crystalline grains and enables the spindles to have a higher specific surface area and smaller pore sizes, leading to superior sensitivity towards triethylamine (TEA) in gas sensing applications.
