  Catalysts prepared from abundant, cost effective metals, such as cobalt, nickel, chromium, manganese, iron, and copper, and containing one or more neutrally charged ligands (e.g., monodentate, bidentate, and/or polydentate ligands) and methods of making and using thereof are described herein. Exemplary ligands include, but are not limited to, phosphine ligands, nitrogen-based ligands, sulfur-based ligands, and/or arsenic-based ligands. In some embodiments, the catalyst is a cobalt-based catalyst or a nickel-based catalyst. The catalysts described herein are stable and active at neutral pH and in a wide range of buffers that are both weak and strong proton acceptors. While its activity is slightly lower than state of the art cobalt-based water oxidation catalysts under some conditions, it is capable of sustaining electrolysis at high applied potentials without a significant degradation in catalytic current. This enhanced robustness gives it an advantage in industrial and large-scale water electrolysis schemes.

  本文描述了由丰富、成本效益的金属（如钴、镍、铬、锰、铁和铜）制备的催化剂，其中包含一个或多个中性配体（例如，单齿、双齿和/或多齿配体）及其制备和使用方法。示例配体包括，但不限于，膦配体、氮基配体、硫基配体和/或砷基配体。在某些实施例中，催化剂是基于钴或基于镍的催化剂。本文描述的催化剂在中性pH值下以及在既是弱质子受体又是强质子受体的各种缓冲液中都是稳定和活性的。在某些条件下，虽然其活性略低于现有技术水氧化钴基催化剂，但它能够在高施加电位下维持电解而不会出现催化电流的显着降解。这种增强的稳健性使其在工业和大规模水电解方案中具有优势。
