Ordered porous BiVO4 based gas sensors with high selectivity and fast-response towards H2S

Seeking for novel materials that show pronounced gas sensing performance has been of great interests from both academic and technological perspectives. Herein, we report for the first time the gas sensing properties of monoclinic phase BiVO4 porous films with high selectivity and low detection limit towards H2S. The porous film with honeycomb-like morphology was in situ synthesized based on the solution dipping strategy using monolayer colloidal...
