Surface modification of nanosheet-type tin oxide with Au-Pd for hydrogen gas sensing

Facile preparation of Au-loaded mesoporous In2O3 nanoparticles with improved ethanol sensing performance

“…Semiconductor metal oxides (SMOs), which are promising gas-sensing materials, have been widely studied for the detection of inflammable, explosive and toxic gases thanks to their high sensitivity, easy preparation and convenient integration. 9–13 Numerous SMOs, such as ZnO, 14–16 SnO 2 , 17–20 In 2 O 3 , 21–23 Fe 2 O 3 , 24–26 TiO 2 , 27 WO 3 28–31 etc. , have been extensively used as sensing materials.…”
