Highly porous CuZnAl layered double hydroxides prepared by biochar-templated co-precipitation method as catalysts for the preferential oxidation of CO reaction
Source abstract
Abstract
This study evaluates the effect of the porosity of Layered Double Hydroxide (LDH) containing copper (Cu), zinc (Zn), and aluminum (Al) synthesized by a co-precipitation method with biochar as a hard template on the preferential oxidation of CO (CO-PROX) reaction. Experimental data showed biochar as a hard template promoted structural changes in the LDH, such as 9 to 42 nm increase in pore size, decrease in the copper oxide crystallite size, and increase in metallic area, and enhanced its activity in the CO-PROX reaction. In situ DRIFTS analyses revealed CO was adsorbed on both Cu + and Cu 0 sites and Cu + was the main species during the reaction for all catalysts.
