Preparation and performance study of mixed metal oxide catalyst for catalytic removal of toluene

As important pollutant in VOCs, toluene has serious impact on people's health and ed by using hydrotalcite as precursor due to the characteristics of its unique composition controllable structure. Thus technical problems difficult control structure high cost nano catalyst were solved. The mixed metal oxide was used for removal catalytic performance studied. results show that with good can be obtained both co-precipitation hydrothermal method. well-structured synthesized range mole ratios 0:2:1 2:0:1 different methods. When reaction temperature is above 80 °C, speed fast crystalline high. efficiency assisted low plasma better than single plasma. best 42.10%, which 1.8 times higher order catalysts follows: Zn-Mg-Al > Cu-Mg-Al Mg-Al Co-Mg-Al.
