With Ce@g-C₃N₄ as a heterogeneous semiconductor photocatalyst, ⁿBu₄NCl as both a redox catalyst and a hydrogen atom transfer catalyst, the first example of semiheterogeneous photocatalytic cross-dehydrogenative coupling of N-heteroarenes and alkanes/ethers with H₂ evolution was developed. Both a diverse array of high-value alkylated N-heteroarenes and clean H₂ can be efficiently coproduced under sacrificial reagent- and chemical oxidant/reductant-free conditions. Combining both the reversible Ce⁴⁺/Ce³⁺ redox pair and the reversible Cl̅/Cl ̇ redox pair can considerably improve the photocatalytic efficiency.

双 Ce@g-C3N4-光氧化还原/氯催化：N-杂芳烃和烷烃/醚与 H2 析出的交叉脱氢偶联


以 Ce@g-C₃N₄ 为非均相半导体光催化剂，ⁿBu₄NCl 为氧化还原催化剂和氢原子转移催化剂，开发了 N-杂芳烃和烷烃/醚与 H₂ 析出的半非均相光催化交叉脱氢耦合的第一个例子。各种高价值烷基化 N-杂芳烃和干净的 H₂ 都可以在无牺牲试剂和化学氧化剂/还原剂的条件下有效地共生产。将可逆的 Ce⁴⁺/Ce³⁺ 氧化还原对和可逆的 Cl̅/Cl ̇ 氧化还原对相结合，可以显著提高光催化效率。
