ELECTROCHEMICAL METHANE OXIDATION TO SYNGAS ON THE PT ELECTRODE IN A CELL WITH THE SOLID OXYGEN-CONDUCTING ELECTROLYTE

Electrochemical methane conversion in a cell with the solid oxygen-con ducting electrolyte (CH4, Pt\0.9ZrO(2) + O.1Y(2)O(3)\Pt + PrO2, air) w as studied. The platinum electrode was found to be an active electrode /catalyst for partial methane oxidation to syngas with the ratio [H-2] /[CO] approximate to 2. At 800 degrees C, the selectivity to carbon mo noxide formation and its yield reach 80 and 65%, respectively. At 660- 700 degrees C, electrochemically generated oxygen oxidizes methane to syngas more efficiently than oxygen adsorbed from the gas phase. New p ossibilities and advantages of the electrochemical route of methane ox idation to syngas were compared to the same process in a normal kineti cs mode.
