Co2 Conversion over Supported CoNi Bimetallic and CoNiPd Trimetallic Catalyst via Dry Reforming with Methane

Greenhouse gas emission is a problem for the earth, and is causing warming of the climate, and acidification of the oceans. The primary objective of this project is to develop novel cobalt based catalysts, to enhance catalytic conversion of CO2 by methane into, value added chemicals and fuels. The heterogeneous Co-based bimetallic and tri metallic catalysts were synthesized via a wet incipient impregnation method to uniformly coat the metal salts to the pre-treated support (TiO2, SiO2, and La-ZrO2). The catalyst was dried in the oven at 80∞ C for two hours before subjected to the furnace to calcine at 450 degrees C for five hours. The synthesized catalysts are to be tested for CO2 dry reforming with methane through a flow bed reactor with controlled CO2 and CH4 flow rate and on-line GC to determine selectivity, conversion and stability of the catalysts. Catalyst characterization such as Brunauer Emmett Teller (BET) surface area, pore size and volume, Transmission Electron Microscope (TEM), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and CO Chemisorption and Temperature Programed Reaction (TPR) will be carried out at Brookhaven National Laboratory with an aim to establish relationships between activity and properties. The fundamental study will serve as great guidance for us to understand the reaction pathway of dry reforming of CO2 with CH4
