Title
Hydrogen production by catalytic decalin dehydrogenation over carbon-supported platinum catalyst: Effect of catalyst preparation method
Abstract

•Carbon-supported platinum catalysts were prepared by various preparation methods.•Preparation method affected the catalytic activity in the decalin dehydrogenation.•Platinum dispersion was a crucial factor to determine the catalytic activity.

Preparation method strongly affected the platinum dispersion of carbon-supported platinum catalysts, and accordingly, their catalytic activity in the decalin dehydrogenation. The catalyst prepared by an advanced method (ion-exchange method or polyol method) exhibited a better catalytic performance than that prepared by a conventional method (impregnation method or precipitation method) in terms of initial hydrogen evolution rate and total amount of hydrogen evolution. Platinum dispersion played a key role in determining the catalytic activity in this reaction, and thus, the high platinum dispersion of the catalysts prepared by an ion-exchange method and a polyol method resulted in their high catalytic activity.
