Gas Sensors
In article number 2214008, Il‐Doo Kim and co‐workers investigated photosensitization of the TiO2‐In2O3 sensing layer to enhance the NO2 detection capabilities of oxides. The heterogeneous interface engineered between two dissimilar oxides improved the accumulation of photogenerated charge carriers, which accelerated the adsorption and desorption of NO2 molecules. The study elaborates on...
Activation of metal oxides by light is a robust yet facile approach to manipulating their surface chemistry for favorable reactions with target molecules in heterogeneous catalysis and gas sensors. However, a limited understanding of interface chemistry and the involved mechanism impedes the development of a rational design of oxide interfaces for light‐activated gas sensing. Herein, the TiOx‐assisted...
