摘要：

Polymeric carbon nitride (CN) as a metal-free photocatalyst with suitable band gap has attracted increasing attention. However, pristine CN has a limited visible-light absorption range and also suffers a high recombination rate of photo-excited charge carriers, resulting in low photocatalytic activity. With the development of modern material characterization technology and electronic structure calculation technology, it is found that vacancy defects in CN play a more decisive role in determining the kinetics, energetics and mechanism of photoca...
