Project Description: TMP catalysts (a type of ceramic-metallic material) are selective and active towards C-O bond rupture during oxygenate hydrodeoxygenation (HDO) for biooil upgrade. Currently, the manner by which the addition of P to transition metal surfaces affects intrinsic energy barriers for C-O, C-H, and C-C bond rupture steps, and the potential for changes in the mechanisms for breaking these bonds, remain unclear between transition metal and TMP catalysts. Thus, a deeper understanding of the influence of P-atoms on surface chemistry in the immediate vicinity would be useful for the design of more active and selective catalysts.
