Special Issue Information

Dear Colleagues,

For the past few decades, bimetallic nanoparticulate catalysts have seen significant advances as this field provides potential opportunities to prepare new catalysts with enhanced activities, selectivities and stability. The initial conceptual development of using bimetallic nanoparticles as catalysts started mainly in hydrocarbon reforming in Exxon laboratories, by Sinfelt and coworkers. However, today various catalytic processes, including selective oxidation, selective hydrogenation/hydrogenolysis, biomass conversion reactions, acetylene hydrochlorination, and many more, use bimetallic nanoparticles and focus on the underlying mechanisms behind the superior catalytic properties of these bimetallic nanoparticles. The surface chemistry of these bimetallic catalysts, including the distribution of two kinds of metal atoms, their packing, surface defects, dispersion on the support, interaction with the support and their electronic effects were considered as major factors responsible for the enhanced catalytic activity of these bimetallic catalysts over their monometallic counterparts. The field of bimetallic catalysis, today, therefore, covers a wide range of applications in homogeneous and heterogeneous catalysis and this Special Issue aims to cover the latest developments in this exciting and promising field of research.

We invite you to submit your research in the form of original research papers, mini reviews, perspectives to this special issue on “Catalytic Applications of Bimetallic Nanoparticles” that reflect state-of-the-art research in bimetallic catalysis, on the following topics: Design and synthesis of supported bimetallic catalysts, bimetallic clusters, bimetallic surface chemistry, microstructure and electronic effects, bimetallic catalysts in C-H activation, bimetallic catalysts in oxidation reactions, reaction kinetics and molecular modelling studies on bimetallic nanoparticles, bimetallic nanoparticles as nanozymes and biocatalysts, environmental remediation using bimetallic nanoparticles, structure–function relationships in bimetallic catalysts, catalyst stability, and passivation and regeneration.

We are eagerly looking forward to receiving your articles for this Special Issue.

Hydroconversion of Aromatic Hydrocarbons over Bimetallic Catalysts

Bimetallic catalysts (BMC) for hydroconversion of aromatic hydrocarbons (ArH) have been designed by modification of Ni/Al2O3 with chromium(0) compounds and phosphoromolybdic heteropolyacid (HPA). Catalysts were tested in hydrogenation of benzene and toluene, in hydrodemethylation of pure toluene and they were shown to possess a high activity, selectivity and sulfur tolerance under conditions of the processes above. The activity of BMC in these processes was much higher as compared with that of two-component (Ni-Cr, Ni-HPA) or conventional Ni/Al2O3 catalysts. Using BMC, hydrogenation of benzene and toluene proceeds with activity increased (up to 34–38 mol/kg·h) and toluene hydrodemethylation may be performed with improved selectivity (90.3%) and benzene yield (81%). The high sulfur tolerance of BMC was demonstrated by performing hydrodemethylation of toluene containing up to 500 ppm S. Full article
