A heterogeneous copper catalyst was developed using a novel techniquesmetallo-organic chemical vapor deposition (MOCVD). Highly porous activated carbon was selected as the catalyst support to provide a high specific area. Copper acetylacetonate was used as the precursor. The precursor was evaporated by heating, transported using carrier gas, deposited into the mesopores and micropores of the support, and finally decomposed and reduced under controlled conditions to elemental metal. A vacuum is applied to enhance the volatility of the precursor. The effects of the carrier gas flow rate and deposition time were studied. The developed catalyst was characterized using the appropriate analytical methods, and its catalytic efficiency was evaluated in the catalytic wet oxidation of phenol solution. The heterogeneous catalyst developed by MOCVD was found to be a monolayer and has a higher catalytic efficiency than that prepared by the impregnation method.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
