构建S型异质结COF/CdS以增强太阳光产氢

高效利用太阳能是解决当前能源危机和环境问题的有效途径.光催化制氢技术具有绿色环保、成本低等优势,且氢气可作为能源载体,其燃烧产物仅为水,因此被认为是实现高效利用太阳能的最佳途径之一.为更好地利用太阳能,研究者们致力于开发具有良好可见光活性的光催化剂.CdS因具有良好的电荷转移能力和在可见光区域强吸收的特性,在光催化制氢...     

Z型光催化体系中存在的电荷转移机理问题（英文）

<正>Photocatalysis is a sunrise technology with great potential for hydrogen production^1,2, carbon dioxide reduction³, and so on. However, a single-component photocatalyst often exhibits severely limited activity due to rapid photogenerated carrier recombination and weak redox abilities. To cope with the downsides of single-component photocatalysts, Bard pioneered the construction of Z-scheme photocatalysis in 1979⁴.
