Photocatalytic hydrogenation of biomass‐derived organic molecules transforms solar energy into high‐energy‐density chemical bonds. Reported herein is the preparation of a thiophene‐containing covalent triazine polymer as a photocatalyst, with unique donor‐acceptor units, for the metal‐free photocatalytic hydrogenation of unsaturated organic molecules. Under visible‐light illumination, the polymeric photocatalyst enables the transformation of maleic acid into succinic acid with a production rate of about 2 mmol g⁻¹ h⁻¹, and furfural into furfuryl alcohol with a production rate of about 0.5 mmol g⁻¹ h⁻¹. Great catalyst stability and recyclability are also measured. Given the structural diversity of polymeric photocatalysts and their readily tunable optical and electronic properties, metal‐free photocatalytic hydrogenation represents a highly promising approach for solar energy conversion.

使用共价三嗪聚合物的无金属光催化加氢。

生物质衍生的有机分子的光催化氢化将太阳能转化为高能密度化学键。本文报道了一种具有噻吩的共价三嗪聚合物作为光催化剂的制备方法，该聚合物具有独特的供体-受体单元，可用于不饱和有机分子的无金属光催化加氢。在可见光照射下，聚合光催化剂能够以约2 mmol g ^-1  h ^-1的生产率将马来酸转化为琥珀酸，并以约0.5 mmol g ^-1  h的速率将糠醛转化为糠醇。^-1。还测量了催化剂的稳定性和可回收性。鉴于聚合物光催化剂的结构多样性及其易于调节的光学和电子特性，无金属光催化氢化代表了一种非常有前途的太阳能转化方法。
