摘要在可见光照射和环境友好条件下进行选择性有机转化的新型多相光催化剂的研究和开发仍然是精细化工领域的热点之一。在这里，我们报道了钴卟啉负载的氮磷共掺杂石墨烯量子点/石墨烯（CoPP@N, P: GQD/G）的合成，以及它们在可见光照射下作为高效、可回收和不含贵金属的多相光催化剂在醇的好氧氧化反应中的令人瞩目的性能。就催化活性而言，在相同的反应条件下，这些催化剂比大多数报道的光催化剂具有更高的转化率（约92%）和选择性（约86%）。该研究指出CoPP@N， P: GQD/G光催化剂在环境和绿色条件下具有高活性和选择性，反应时间短，可重复使用和易于分离的优点，在好氧氧化反应中具有相当大的潜力。图形抽象
AbstractThe research and development of the new heterogeneous photocatalysts for selective organic transformations under visible-light irradiation and environmentally friendly conditions is still considered as one of the hot topics in the fine chemical industry. Here, we report the synthesis of cobalt porphyrin-supported nitrogen and phosphorus co-doped graphene quantum dots/graphene (CoPP@N, P: GQD/G) and their impressive performance as efficient, recyclable, and noble metal free heterogeneous photocatalysts in the aerobic oxidation reaction of alcohols under visible-light irradiation. In terms of catalytic activity, these catalysts afford much higher conversion (ca. 92%) and selectivity (ca. 86%) than most reported photocatalysts under the same reaction conditions. This work notes the considerable potential of CoPP@N, P: GQD/G photocatalysts in the aerobic oxidation reaction owning to high activity and selectivity, short reaction time, reusability and easy separation under ambient and green conditions.Graphical Abstract
