2,4-Dichlorophenol (2,4-DCP) is widely used as a preservative, pesticide, germicide, etc. However, it is very damaging to organisms and the environment, and it is difficult to decompose because of its high stability. To improve the photocatalytic ability of photocatalysts for degrading hazardous substances, like 2,4-DCP, constructing heterojunction is an effective strategy because of its restraint of electron–hole recombination and extension of light absorption spectra.

Bi7O9I3/BiOIO3/g-C3N4 新型双 Z 型异质结在可见光照射下高效去除 2,4-二氯苯酚：性能和机理

2,4-二氯苯酚（2,4-DCP）被广泛用作防腐剂、杀虫剂、杀菌剂等，但对生物体和环境的破坏性很大，而且由于稳定性高，不易分解。为了提高光催化剂降解有害物质（如 2,4-DCP）的光催化能力，构建异质结是一种有效的策略，因为它可以抑制电子-空穴复合并扩展光吸收光谱。
