摘要：

Non-stoichiometric ratio semiconductor materials have exhibited excellent performance in energy conversion and storage fields. However, the hydrogen treatment method that is commonly used to introduce oxygen vacancies is expensive and dangerous. In this paper, a novel microbattery method using Zn powder and Fe powder as reductant has been developed to synthesize the oxygen vacancy modified WO 3-x films and oxygen-deficient heterojunction films (ZnWO 4-x /WO 3-x and Fe 2 O 3-x /WO 3-x ) at room temperature. The as-prepared WO 3-x and ZnWO 4-x /W...
