摘要：
Using oxygen in the air as the sole oxidant to oxidize hydrocarbons into high value-added compounds is a highly promising synthesis strategy with economic advantages. However, the oxidation of hydrocarbons with molecular oxygen under mild conditions is challenging due to the large C-H bond energy in hydro-carbons. Herein, a metal-free two-dimensional covalent organic polymers (COP) functionalized by pho-toactive pyridinium units has been developed for heterogeneous photocatalytic oxidation of hydrocarbons. This is the first kind of COPs material that can achieve photocatalytic oxidation of hydro-carbons without any additives or stoichiometric oxidants except for the oxygen in the air.(c) 2022 Elsevier Inc.
