Synthesis of mesostructured indium oxide doped with rare earth metals for gas detection

• A nanocasting synthesis of mesostructured In2O3 doped with rare earth metals.
• The ordered mesostructures were well maintained with high surface area.
• Materials are highly sensitive and selective to NH3 gas.

Utilizing an improved one-step nanocasting method, ordered mesostructured In2O3 doped with different rare earth metals was synthesized. The obtained materials showed tunable doping ratios and ordered pore structure with high surface area, which led to remarkable sensitivity and selectivity for NH3 gas.
