Na+-doping induced synergistic oxygen vacancies and compressive strain for enhanced photocatalytic formaldehyde mineralization.
The efficiency of photocatalytic formaldehyde (HCHO) mineralization is often limited by insufficient adsorption and activation of O2 and HCHO on conventional semiconductor surfaces. In this work, we demonstrate a 'kill two birds with one stone' strategy-Na+ doping in ZnWO4-which simultaneously introduces oxygen vacanci...
