Researchers led by Dr. Fumiaki Amano, an associate professor in the Department of Chemical and Environmental Engineering at the University of Kitakyushu, have dealt with an important goal in energy and environmental chemistry, which is a conversion of methane (CH4) into valuable chemicals. Herein, they reported a photoelectrochemical (PEC) system for selective oxidation of gaseous CH4 under visible light irradiation at room temperature. Carbon–carbon coupling of CH4 to form ethane (C2H6) was induced by photogenerated holes over a tungsten trioxide (WO3) gas-diffusion photoanode coated with a proton-conducting polymer. The fabricated PEC system can realize an anaerobic activation of CH4 at low temperature with high quantum efficiency under low-energy visible light.
The research was performed in collaboration with Dr. Teruhisa Ohno of Kyushu Institute of Technology and Dr. Sakae Takenaka of Doshisha Univeristy, supported by the Precursory Research for Embryonic Science and Technology (PRESTO) program.
