Zusammenfassung:The invention discloses a method for concerted catalytic oxidation of VOCs (volatile organic compounds) and mercury by a TiO2-loaded MnOx-CeOx catalyst. The catalyst is composed of a {101} high-energy crystal face exposed TiO2 carrier, MnOx and CeOx and is prepared by depositing MnOx and CeOx on {101} high-energy crystal face exposed TiO2 through a deposition method, the {101} high-energy crystal face exposed TiO2 carrier is prepared through a hydrothermal method, Mn (NO3) 2, KMnO4 and Ce (NO3) 3.6 H2O serve as metal sources of active components MnOx and CeOx, MnOx accounts for 5%-15% of the total mass of the catalyst, CeOx accounts for 5%-15% of the total mass of the catalyst, and the balance is TiO2. The catalyst prepared by the invention is a truncated octahedron, has a larger specific surface area, provides more active sites for gaining and losing electrons, and can efficiently and synergistically catalyze and oxidize VOCs and Hg0. 本发明公开一种TiO2负载MnOx-CeOx催化剂协同催化氧化VOCs和汞的方法。本发明的催化剂由{101}高能晶面暴露TiO2载体、MnOx和Ce
