Selective Oxidation and Hydrochlorination Catalysis with Noble Metal Nanoparticles
This research community develops heterogeneous catalysts, primarily based on gold and other noble metals, to drive selective chemical transformations such as the aerobic oxidation of alcohols and the hydrochlorination of acetylene. The work aims to create efficient, stable, and highly selective materials for the production of fine chemicals and industrial feedstocks.
The recurring technical focus is on the synthesis and characterization of supported metal nanoparticles, with a heavy emphasis on gold and nanoporous gold structures. Key chemical reactions include the selective aerobic oxidation of benzyl alcohol and other alcohols, as well as the hydrochlorination of acetylene to vinyl chloride. The community also investigates propylene epoxidation using molecular oxygen and the oxidation of glycerol. Methodologies center on tuning catalyst activity through support interactions, bimetallic pairings, and precise control of nanoparticle size and morphology to achieve high selectivity in liquid-phase reactions.
The largest share of the community's output is found in gold research, accounting for 1.3% of all gold research, with 2,612 papers in this group. Oxygen research contributes the second-largest share at 0.3%, followed by carbon at 0.2%.
The community comprises 9,734 papers, publishing most frequently in the Journal of Catalysis, Tetrahedron Letters, and Catalysis Today.
Recent work continues to explore bimetallic catalytic pairs, such as copper and gold systems, for selective alkyne conversion and aerobic oxidation. New developments include metal-free catalysts for acetylene hydrochlorination and gold catalysts stabilized in zeolites for propylene epoxidation, alongside investigations into the structural plasticity of metallic nanosponges.
