摘要
Electrocatalytic oxidation of methane over Pt-based electrode-catalyst in a solid oxide fuel cell reactor CH4 Pt0.9ZrO(2) + 0.1Y(2)O(3)\Pt, air was studied at 800 degrees C and atmospheric pressure, SEM and ESCA techniques were used to characterize the electrode-catalyst, It is found that the Pt-based electrode is an active electrode-catalyst for partial oxidation of methane (in a diluent absence) to syngas, concentration ratio being [H-2]/[CO]approximate to 2. Methane conversion and carbon monoxide selectivity attained 97% and 95%, respectively, Under these conditions, reactor is operated in a fuel cell mode and the electrode-catalyst is stable (to coking, too), (C) 1999 Elsevier Science B.V.
