True as steel: We report the efficient electrolysis of water by cobalt-based water-oxidation catalysts electrodeposited on a 3 D mat of stainless-steel microfibers to form a core–shell structure. Owing to the high surface activity of the cobalt-based catalysts and an enhanced local electric field, the core–shell catalysts exhibit exceedingly high catalytic performance for water oxidation at a neutral pH.

不锈钢超细纤维上的钴基薄层催化剂，可有效电解水

像钢铁一样真实：我们报告说，通过在3D不锈钢微纤维垫上电沉积钴基水氧化催化剂可以有效地电解水，从而形成核-壳结构。由于钴基催化剂的高表面活性和增强的局部电场，核-壳型催化剂在中性pH值下对水氧化具有极高的催化性能。
