Energy crisis, greenhouse effect and global warming have become common problems in the world. Since these problems appeared, people many efforts have been made to try to solve them. Photocatalysis can solve these problems well with great research value. First of all, photocatalysis utilize the clean energy of solar energy as the drive, triggering, directing and accelerating the chemical reactions, which is a green catalytic way; Secondly, they can catalyze many reactions, such as hydrogen evolution, carbon dioxide reduction and the degradation of organic contaminants, making contributions to improving the environment; Finally, photocatalysis can result on obtaining products with high economic relevance such as the synthesis of complex organic molecules. At present, materials based on titanium dioxide, zinc oxide, tin oxide, zirconium dioxide, and cadmium sulfide are the most popular photocatalysts. However, these traditional photocatalysts suffer from weak light absorption capacity, difficulty in activation, easy electron–hole recombination, poor stability, and other issues. Thus, how to find efficient photocatalysts remains a great challenge.


Advantages of MOFs and COFs in Photocatalysis

MOFs and COFs are the promising efficient photocatalyst materials, compared with the traditional materials, MOFs and COFs demonstrate the following advantages[1]:

  • Designable structures and components: the absorption capacity and band structure of MOFs and COFs can be finely adjusted by changing the chemical structure of monomer, such as the inclusion of suitable π-units into their well-ordered extended structures that confer photocatalytic activity.
  • Easy to functionalize: MOFs and COFs can be functionalized in different ways, thus facilitating the introduction of photocatalytic sites.
  • High specific surface areas and good stability: this allows the catalytic sites on the MOFs and COFs that disperse efficiently, fully expose and remain stable during the photocatalytic processes.
