Article Synopsis
- The study presents a new type of ammonia (NH) sensor made with nickel-doped cerium oxide (Ni-doped CeO), capable of detecting NH concentrations as low as 45 parts per billion (ppb) at room temperature.
- It shows a significantly enhanced response (42) towards higher concentrations (225 ppm) compared to pure CeO, achieving performance improvements through the creation of oxygen vacancies and changes in bandgap and redox properties due to the doping.
- The findings support the idea that engineering defects, like incorporating Ni into the CeO structure, can improve sensor capabilities, making this research valuable for developing advanced air quality monitoring technologies.
The toxic nature of inorganic nanostructured materials as photocatalysts is often not accounted for in traditional wastewater treatment reactions. Particularly, some inorganic nanomaterials employed as photocatalysts may release secondary pollutants in the form of ionic species that leach out due to photocorrosion. In this context, this work is a proof-of-concept study for exploring the environmental toxicity effect of extremely small-sized nanoparticles (<10 nm) like quantum dots (QDs) that are employed as photocatalysts, and in this study, cadmium sulfide (CdS) QDs are chosen.
