Description
Summary:Photoelectrocatalysis The cover image, highlighting the work by Fatwa Firdaus Abdi, Yun Hau Ng, and co‐workers in article number 2102023, shows the photoelectrochemical water oxidation on an illuminated plate‐like bismuth tungstate photoanode thin film. The tungsten concentration is modulated to tune the photoexcited charge transportation of the thin film. This “self‐doped” of tungsten leads to the higher carrier density and improved conductivity for oxygen evolution from water.
