Aqueous acid treatment of bi- and trimetallic Mo(W)S2 sulfides removed a majority of Ni sulfides without affecting the intactness of the Mo(W)S2 slabs. Reaction path analysis of quinoline hydrodenitrogenation (HDN) on these samples suggests identical

High concentrations of Ni in bimetallic sulfide catalysts lead to the formation of segregated Ni sulfides (NiSx), which are rather inactive alone as large crystallites and even impede the accessibi...

The reduction of metal precursors during the polyol synthesis of metal nanoparticles was monitored by ex situ ionic conductivity measurements. Using commonly used platinum precursors (K2PtCl6, H2PtCl6, and K2PtCl4) as well as iridium and ruthenium pr

The mechanism of the deoxygenation of fatty acids on transition-metal sulfides was determined on the basis of kinetic data obtained with fatty acids, their reaction intermediates (aldehyde and alcohol), and reactants of restricted reactivity (adamant

The impact of the zeolite Bronsted and Lewis acid site concentration on the catalytic cracking of alkanes was explored using n-pentane and H-ZSM-5 as examples. Rates normalized to strong Bronsted acid sites (i.e., the turnover frequencies, TOF) showe
