W-Sn Mixed Oxides and ZnO to Detect NOx and Ozone in Atmosphere

W-Sn Mixed Oxides and ZnO to Detect NOx and Ozone in Atmosphere

Thick films of zinc oxide (ZnO) in form of nanospheres or hexagonal prisms and of tungsten-tin (W-Sn) mixed oxides at nominal Sn molar fraction (0.1, 0.3 and 0.5) were prepared. The functional materials were synthesized and characterized by SEM and TEM, X-ray diffraction, specific surface area measu...
