Influence of the niobium supported species on the catalytic dehydration of glycerol to acrolein

[Display omitted] •Supported niobium oxide catalysts are active in glycerol dehydration to acrolein.•Acrolein selectivity is related to the existence of Brönsted acid sites.•Brönsted acid sites are generated in presence of water vapor.•Lewis acid sites are more stable but less selectivity.•Brönsted...
