Enhanced photo-degradation of bisphenol a under simulated solar light irradiation by Zn–Ti mixed metal oxides loaded on graphene from aqueous media

Abstract

In the present study, the mixed metal oxides (rGO-ZnTi-MMO-x, x presents weight percentage of GO) were obtained by thermal treatment of a Zn–Ti layered double hydroxides-graphene oxide (GO-ZnTi-LDHs) composite.

Facile Preparation of ZnO Nanoparticles and Ag/ZnO Nanocomposite and Their Photocatalytic Activities under Visible Light

“…There have been many studies on synthesizing ZnObased materials to decompose toxic organic substances in wastewater [9,[34][35][36][37], in which ZnO/TiO 2 and ZnO/rGO-rGH showed the effective materials of degrading BPA under UV irradiation [38,39]. However, the use of UV light can affect the ecosystem as well as it is much more expensive than using visible light.…”

Importance of ZnTiO3 Phase in ZnTi-Mixed Metal Oxide Photocatalysts Derived from Layered Double Hydroxide

“…ZnTi-mixed metal oxide (ZTM), which is one of these mixed metal oxides, has been used as a heterogeneous catalyst, in which the charge separation efficiency of photogenerated electron–hole pairs was improved within this intra heterojunction for enhancing the rate of reaction with high efficiency. − ZnTiO 3 is an environmentally friendly and promising material for a variety of applications, including dehydrogenation reactions, microelectronics, optics, low temperature cofired ceramics, and potential photocatalysis. − Different synthetic strategies, such as codoping, improved the photocatalytic activity of ZnTiO 3 perovskites toward applications in visible light regions . Niasari et al have reported that in the sol–gel method, the ZnTiO 3 photocatalyst has shown a high photocatalytic efficiency for methyl orange degradation under UV light.…”
