Nickel Catalysts in Catalytic Hydrogenation

Catalytic control of automobile exhaust emissions

“…Catalytic studies on hydrocarbon and carbon monoxide oxidation have demonstrated 35 that an unsupported cobalt-oxide catalyst exhibits high engine-exhaust conversion efficiency after 200 hours of operation. However, on an alumina support (20 wt% cobalt oxide), prolonged use leads to marked decrease in catalytic conversion.…”
