What is Bismuth Phosphate Nanoparticle Catalyst for Direct Oxidation of Methane Into Formaldehyde about?
The direct oxidation of methane (CH 4 ) to formaldehyde (HCHO) with molecular oxygen (O 2 ) as the sole oxidant was studied over various bismuth-based catalysts (BiPO 4 , α-Bi 2 O 3 , β-Bi 2 O 3 ) using a fixed-bed flow reactor. The catalytic activity of monoclinic BiPO 4 nanoparticles (BiPO 4 -DEG) synthesized in a mixed solvent of diethylene glycol (DEG) and water for the direct oxidation of CH 4 was the highest among the catalysts tested. In high temperature region, BiPO 4 -DEG was more selective for HCHO formation than FePO 4 nanoparticles. Based on mechanistic studies including the catalyst effect, kinetics, pulse-reaction experiments, infrared (IR) spectroscopy, operando near ambient pressure X-ray photoelectron spectroscopy (NAP-XPS), and density functional theory (DFT) calculations, surface active oxygen species generated on BiPO 4 possibly react with CH 4 to give HCHO as the primary product. In contrast, the phosphate units of FePO 4 nanoparticles react with CH 4 followed by rapid reoxidation to FePO 4 .
