Inorganic salts have been widely studied as templates for the synthesis of 2D layer structures. However, these salts normally can only serve as templates without any catalytic activity. Here, we report that LiCl used for the synthesis of ultrathin nanosheets not only serves as template for the synthesis of ultrathin Co₂P nanosheets with a thickness of 0.7 nm but also acts as a catalyst that induces the phase‐transfer from CoP to Co₂P. The Co₂P nanosheets have a high electrochemical performance for oxygen evolution reaction.

LiCl作为相转移催化剂来合成用于氧气释放反应的Co2P纳米薄板

无机盐已被广泛研究为2D层结构合成的模板。但是，这些盐通常只能用作模板而没有任何催化活性。在这里，我们报道了用于合成超薄纳米片的LiCl不仅用作合成厚度为0.7 nm的超薄Co ₂ P纳米片的模板，而且还充当了诱导从CoP到Co ₂的相转移的催化剂。P. Co ₂ P纳米片对氧释放反应具有很高的电化学性能。
