A room-temperature aniline sensor based on Ce doped ZnO porous nanosheets with abundant oxygen vacancies

Yong-Hui Zhang et al.

Summary: The paper discusses the successful synthesis of Ce-doped ZnO porous nanosheets and their sensing properties towards aniline at room temperature. The Ce-doped ZnO sensor exhibited high response and excellent selectivity due to the abundant oxygen vacancies, high specific surface area, and interface interaction between CeO2 and ZnO. The DFT study results indicated enhanced interaction between ZnO and aniline by introducing oxygen vacancies and Ce doping, suggesting that CZO composites could be a potential candidate for aniline detection at room temperature.
