Dihydrogen sulphide (H2S) is a dangerous pollutant released in fossil combustion processes. Here, p-CuO (particle)/n-SnO2 (nanowire) heterostructures were evaluated as selective H2S sensors, and the working principle behind their good performance was

Powders of tin dioxide (SnO2) have been prepared by two different modifications of wet chemical synthesis, i.e. (i) by conventional hydrolysis of tin chloride dissolved in aqueous ammonia solution and (ii) by precipitation from tin chloride dissolved

Highly crystalline SnO2 nanowires were synthesized and functionalized with copper particles in a CVD using Sn(OBut)4 and [CuII((C5H4N)(CHCOCF3))2]2 (1) as precursors respectively. Controlled oxidation of Cu to CuO led to the formation of CuO@SnO2 p
