过氧化氢（H2 O2）是一种需求量日益增长的氧化剂和消毒剂，通过选择性双电子氧还原反应（2 e（-）ORR）可以实现现场电化学生产，但该方法的广泛采用依赖于稳定高效的电催化剂。目前的催化剂受到成本或毒性的限制，并且缺乏可以促进活性和选择性的系统调节的明确定义的结构。在这里，我们展示了一系列CuCo_（2-x）Ni_xS_4（0
On-site electrochemical production of hydrogen peroxide (H2O2), an oxidant and disinfectant with growing demand, could be realized through the selective two-electron oxygen reduction reaction (2e(-) ORR), but the widespread adoption of this method depends on robust and efficient electrocatalysts. Current catalysts have been limited by cost or toxicity and lack well-defined structures that can facilitate systematic tuning of activity and selectivity. Here, we demonstrate a series of CuCo2-xNixS4 (0
