The design of robust, high‐performance photocatalysts is key for the success of solar fuel production by CO2 conversion. In this study, hypercrosslinked polymer (HCP) photocatalysts have been developed for the selective reduction of CO2 to CO, combining excellent CO2 sorption capacities, good general stabilities, and low production costs. HCPs are active photocatalysts in the visible light range, significantly outperforming the benchmark material, TiO2 P25, using only sacrificial H2O. It is hypothesized that superior H2O adsorption capacities facilitate access to photoactive sites, improving photocatalytic conversion rates when compared to sacrificial H2. These polymers are an intriguing set of organic photocatalysts, displaying no long‐range order or extended π‐conjugation. The as‐synthesized networks are the sole photocatalytic component, requiring no added cocatalyst doping or photosensitizer, representing a highly versatile and exciting platform for solar‐energy conversion.

超交联聚合物作为光催化平台,利用 H2O 进行可见光驱动的 CO2 光还原

坚固、高性能光催化剂的设计是通过 CO 2转化成功生产太阳能燃料的关键。在这项研究中,超交联聚合物(HCP)光催化剂被开发用于选择性地将CO 2还原为CO,兼具优异的CO 2吸附能力、良好的总体稳定性和较低的生产成本。HCP 是可见光范围内的活性光催化剂,其性能显着优于仅使用牺牲 H 2 O 的基准材料 TiO 2 P25 。据推测,与 HCP 相比,卓越的 H 2 O 吸附能力有利于进入光活性位点,从而提高光催化转化率牺牲H 2。这些聚合物是一组有趣的有机光催化剂,不显示长程有序或扩展的 π 共轭。合成的网络是唯一的光催化成分,不需要添加助催化剂掺杂或光敏剂,代表了一个高度通用且令人兴奋的太阳能转换平台。
