Oxygen vacancy engineering plays a crucial role in regulating surface chemistry for managing redox behaviors. However, controllable implantation of oxygen and safe cost-effective production remain challenging. Herein, we report general molten zinc reduction technology to prepare oxygen-deficient oxides with tunable content, synthetic universality, industrial compatibility under mildly elevated temperature. Taking TiO2 as an example, theoretical study demonstrates thermodynamically favorable affinity on increasing coverage supporting Zn supply. Featuring electronic structures inferior hydrogen evolution activity, TiO2-x nanoparticles were used decorate aqueous anodes, which demonstrate much improved cycling stability, verified by situ ex investigations. Eventually, zinc-iodine batteries assembled using modified achieved performance due the regulated anode alleviated self-discharge This work provides in-depth understanding durable related systems.
