Semiconductor photocatalysis technology emerges as a “green technology” to remedy the problems resulting from the increasing energy shortages and environmental degradation.Recent studies on introduction of oxygen vacancies in semiconductor photocatalysts have shown great promise towards the increase in photo-response range as well as improved photoactivity.Herein,we have prepared Zn WO4 sample with oxygen vacancies(denoted as ZnWO_4-x)by the solvothermal treatment of Zn（NO₃）...
