Summary: CO2 cycloaddition with epoxides is an important process for CO2 conversion to generate cyclic carbonates. However, the catalytic efficiency of porous organic polymers (POPs) for this process is typically low and requires severe conditions or prolonged reaction time. In this study, amine-impregnated porous organic polymers (HCP-TPP-Co-EDA-10 and HCP-TPP-Co-PEI-5) were developed to enhance the interaction with CO2 and improve catalytic efficiency. These catalysts exhibited strong binding affinity with CO2 and high catalytic yield under mild conditions. The turnover number (TON) and turnover frequency (TOF) achieved were among the highest reported so far. Additionally, the catalysts showed excellent recyclability and stability for CO2 conversion. The use of amines as chemisorption sites for CO2 provides a simple strategy for designing highly efficient functionalized hyper-cross-linked polymers (HCPs) for CO2 capture and chemical conversion.

Summary: Photocatalytic hydrogen evolution through water splitting using covalent triazine frameworks (CTFs) offers a promising route for solar energy conversion. However, the typical powder form of CTF-based photocatalysts poses challenges in recycling and scale-up applications. To address this limitation, CTF films were developed by in-situ growth polycondensation on glass substrates, demonstrating exceptional photocatalytic activity, stability, and recyclability. These films show a high hydrogen evolution rate and hold potential for green energy conversion and photocatalytic devices.
