摘　　要：过氧化氢(H_(2)O_(2))是一种高效的氧化剂,被广泛应用于化学合成、消毒杀菌和废水处理.通过二电子氧还原反应(2e^(-)ORR)原位电合成H_(2)O_(2)的方法具有高性能和环保性,可作为传统蒽醌工艺的替代策略.气体扩散电极(GDEs)可作为阴极,通过电催化生产H_(2)O_(2),具有更低的成本、更低的能耗和更高的氧气利用效率等优点.探讨GDEs作为阴极时通过2e^(-)ORR产H_(2)O_(2)的机制;讨论GDEs的基本构型、原理及优化方法;分析GDEs催化剂的种类及优势;展望了GDEs作为阴极原位制备H_(2)O_(2)时存在的挑战,为推动2e^(-)ORR原位电合成H_(2)O_(2)迈向市场化提供借鉴.Hydrogen peroxide(H_(2)O_(2)),a highly effective oxidant,is widely used in chemical synthesis,sterilization and wastewater treatment.Traditional anthraquinone process was replaced by H_(2)O_(2)electrosynthesis via two-electron oxygen reduction(2e^(-)ORR),because of its high performance and environmentally friendly property.As a high-efficiency H_(2)O_(2)production cathode,gas diffusion electrodes(GDEs)exhibit lower cost,lower energy consumption and higher oxygen utilization efficiency.In this paper,we investigate the mechanism of H_(2)O_(2)production by 2e^(-)ORR with GDEs.Besides,the configuration,principle and optimization method of GDEs are discussed.The GDEs catalysts were also analyzed.Finally,some future directions are pointed out,which is beneficial to promote the H_(2)O_(2)electrosynthesis towards marketization.
