Structural evolution of the Prussian blue analogue precatalysts has been attained by replacing a −CN group with strong π-acidic −NO. This in turn tunes the electronic and atomic structures and electrochemical properties of the active catalyst and a significant improvement in the alkaline water oxidation activity has been observed.

破译配体控制普鲁士蓝类似物的结构演变及其在碱性水氧化过程中的电化学活化

普鲁士蓝类似物预催化剂的结构演变是通过用强 π-酸性 -NO 取代 -CN 基团实现的。这反过来又调整了活性催化剂的电子和原子结构以及电化学性质，并且已经观察到碱性水氧化活性的显着改善。
