摘要

众所周知,合成异质结光催化剂可以提高光催化活性。本文通过简便的合成方法,成功地将uuo -66与[公式:见文]-C3N4结合成超薄层涂层,通过对RhB的降解,显示出高效的光催化性能。异质结和高比表面积使光催化剂能够促进可见光吸收,加强光生电子的分离和迁移,最终导致光催化降解性能的提高。异质结构纳米催化剂使RhB在可见光照射下140 min降解率达到98.98%[公式:见文]。此外,孔(h[公式:见文])在反应中起主要作用。本工作为其在环境退化领域的应用提供了一种有效的方法。

Fabrication of UiO-66/g-C3N4 Heterostructure Nanocatalyst for Efficient Visible-Light Photocatalytic Performance
It is well known that synthetic heterojunction photocatalysts can promote photocatalytic activity. Herein, we successfully combine UiO-66 with [Formula: see text]-C3N4 as ultrathin layer coating via a convenient synthesis method, the photocatalytic performance through the degradation of RhB is then shown efficient. The heterojunction and high surface area give the photocatalysts an ability to promote visible light absorption and strengthen the separation and migration of photogenerated electrons, which ultimately leads to the improvement of photocatalytic degradation. The heterostructure nanocatalyst helps the degradation rate of RhB reach 98.98% in 140[Formula: see text]min under visible light irradiation. In addition, the hole (h[Formula: see text]) plays a major role in the reaction. This work offers an efficient method for the application in the field of environmental degradation.
