Abstract
A process for reducing perfluorinated compounds and/or hydrofluorocarbon compounds in a sample uses a catalyst made from aluminum oxide (Al2O3), and one or more enhancers selected from the group consisting of nickel, cobalt, and sulfate. Another useful catalyst comprises zirconium oxide (ZrO2) and/or aluminum oxide (Al2O3) and nickel as an enhancer.
