•Pure carbon xerogels with fitted porosity were prepared by sol-gel technology.•Activated carbons contain mineral matter in different proportion and nature.•The developed mesoporosity and acid impurities favor secondary reactions.•Secondary reactions are avoided using microporous spherical carbon xerogels.
The role of activated carbons and carbon xerogels as Pt-supports for the selective citral hydrogenation is compared. The influence of porosity and inorganic matter impurities in activated carbons determines the performance of their derivative catalysts. The presence of Pt-particles inside mesopores and acid mineral matter favors secondary reactions decreasing the unsaturated alcohols (UA) yield. Highly active and selective monometallic Pt-catalysts were obtained using pure carbon xerogels structured in microspheres as support.
