Study on the selectivity of propane photo-oxidation reaction on SBA-15 supported Mo oxide catalyst
•Selective oxidation reaction of propane on Mo/SBA photo-catalyst was studied.•The local structure of Mo/SBA was able to be controlled by loading amount of Mo.•The selectivity of propane photo-oxidation was dependent on the local structure of Mo species.
SBA-15 supported Mo oxide catalysts (Mo/SBA) were prepared and the local structures of the Mo species were investigated by X-ray diffraction (XRD) and X-ray absorption fine structure (XAFS) measurements. The local structure of Mo on Mo/SBA was able to be controlled from Td monomer to Oh oligomer by increasing the Mo loading. The selectivity of propane photo-oxidation reaction was dependent on the local structure of Mo species.
