WebApr 11, 2024 · In this study, we report on the rapid preparation of WO3 nanoplates decorated with noble metals and evaluate their gas-sensing performance using a high-throughput screening technique. The incorporation of Pd significantly enhanced the gas-sensing properties, and, among all of the samples tested, the WO3 nanoplate containing 0.3 mol% … WebThe noble gases often do not react with many substances and have been historically called inert gases. Generally, inert gases are used to prevent unwanted chemical reactions which degrade a sample. Oxidation and hydrolysis reactions with the oxygen and moisture in air are often these undesirable chemical reactions. Why inert gases do not react?
