Room-temperature degradation of o-xylene in simulated air using an online-regenerable plasma-catalysis reactor with low amounts of nanosized noble metals on Co3O4

The plasma catalytic degradation of o-xylene in simulated air was improved by loading low amounts of Pt, Pd, or Au onto Co₃O₄. At room temperature, o-xylene conversion and CO_x selectivity using a0.1 wt% Pt/Co₃O₄ catalyst reached 98.9% and 80%, and the energy efficiency was at the top level in comparison with values in the literature. A stable o-xylene degradation performance could be obtained by online regenerating the heat-insulated reactor...
