Metal-free Amorphous Cross-Linked Porous Organic Polymers for Photocatalytic Hydrogen Evolution and Carbon Dioxide Reduction.

The use of solar energy to produce 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.
