Covalent organic frameworks have attracted widespread attention in the field of photocatalytic hydrogen evolution, but their limited light capture ability and charge transfer efficiency still limit performance. Catalysts based on single-crystal semiconductors unique crystal faces show great potential for applications fields energy environment. Here, an organic-inorganic semiconductor heterojunction donor-acceptor covalent framework (COF) has been developed, utilizing intramolecular interfacial built-in electric to enhance mobility photo-generated carriers. Specifically, a COF containing thiophene groups is synthesized through Schiff base reaction, which activates (002) plane CdS by reacting with snowflake-shaped CdS. strong π conjugated structures unevenly distributed electrons surface provide large number reaction system. The synergistic effect CdS/COF heterostructures significantly improves migration carriers, allowing more migrate active sites evolution reaction. This work introduces photocatalyst frameworks, opening up new path efficient clean conversion.

2024, A Landmark Year for Climate Change and Global Carbon Capture, Utilization, and Storage: Annual Progress Review

Energy Science & Engineering, Journal Year: 2025, Volume and Issue: unknown

Published: April 4, 2025

ABSTRACT This annual review outlines the progress of carbon capture, utilization, and storage (CCUS) technologies in 2024. As human‐induced CO 2 emissions continued to rise, year presented critical challenges. Notably, 2024 was hottest on record first which global temperatures exceeded preindustrial levels by more than 1.5°C, driving intensified efforts advance CCUS. Scientific interest CCUS grew significantly, with number related publications increasing 11.4% compared 2023, reaching 53,970. The total operational commercial facilities also expanded, rising 16.3% a 50. In political area, governments introduced targeted policies accelerate adoption, focusing economic investment specific implementation requirements.
