Metal‐free Amorphous Cross‐linked Porous Organic Polymers for Photocatalytic Hydrogen Evolution and Carbon Dioxide Reduction

The use of solar energy for producing valuable chemicals has gained significant attention in recent years. In this area, photocatalytic hydrogen evolution and carbon dioxide reduction have become key focal points. Recently, amorphous cross‐linked porous organic polymers (CPOPs) have emerged as promising photocatalysts due to their tunable band gaps, broad light absorption range, and high porosity. In this article, we highlight recent advancements in cutting‐edge metal‐free amorphous CPOPs for photocatalytic hydrogen evolution and carbon dioxide reduction. We examine the design principles, synthetic strategies, and structure‐property relationships of various cross‐linked porous polymers to achieve high photocatalytic performance. Additionally, we propose future research directions and offer insights to further advance CPOP‐based photocatalysts for efficient solar‐driven hydrogen evolution and carbon dioxide reduction.
