意义La基钙钛矿（LaBO 3）具有优异的光学性能，但很少用于光催化。克服价带（VB）的问题以促进具有挑战性的反应（例如苄基C-H的裂解）构成了重大挑战。我们引入热活化的概念来激发La_2Co_xMn_2-xO_6钙钛矿的光催化活性，并获得优异的催化性能。这一策略有望为基础光化学提供见解，并扩展光催化剂的应用。
Significance La-based perovskites (LaBO3) have excellent optical properties but are rarely used in photocatalysis. Overcoming the issue of the valence band (VB) to promote challenging reactions (such as the cleavage of benzylic C–H) poses a major challenge. We introduce the concept of heat activation to trigger the photocatalytic activity of La2CoxMn2-xO6 perovskites and achieve an excellent catalytic performance. This strategy is expected to provide insights into fundamental photochemistry and extend the applications of photocatalysts.
