Support Effects on NiO-based Catalysts for the Oxidative Dehydrogenation (ODH) of Ethane

We report on the effect of NiO-support interactions on the chemical nature of Ni species in a series of supported NiO catalysts for the ODH of ethane. SiO2, TiO2-anatase, a high surface area TiO2 and a porous clay heterostructure (PCH) with TiO2 and SiO2 pillars were used as supports, which led to a...
