Abstract
A method of selectively catalytically oxidizing dinitrogen oxide present in a gaseous sample, comprising: heating a NiO catalyst to a temperature of at least 250° C.; and bringing the gaseous sample into contact with the heated NiO catalyst to oxidize dinitrogen oxide of the gaseous sample in the presence of the heated NiO catalyst.
