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 g-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 min under visible light irradiation. In addition, the hole (h(+)) plays a major role in the reaction. This work offers an efficient method for the application in the field of environmental degradation.
