Selective Hydrogenation and Catalytic Reduction of Nitroarenes and Alkynes
This community develops heterogeneous catalysts to selectively convert nitro compounds, acetylene, and other organic molecules into valuable intermediates or to degrade pollutants.
The research focuses on designing supported metal nanoparticles, single-atom sites, and bimetallic systems to achieve high selectivity and efficiency. Recurring substrates include 4-nitrophenol, nitroarenes, acetylene, and cinnamaldehyde. Common catalytic metals are palladium, silver, gold, nickel, and platinum, often supported on carbon, graphene oxide, or metal oxides. Key reactions involve chemoselective hydrogenation, transfer hydrogenation, and the reduction of organic dyes. The work emphasizes overcoming activity-selectivity trade-offs through precise control of metal particle size, support interactions, and surface defects.
Palladium research contributes the largest share of this community's output, accounting for 2.0% of all palladium research tracked, with 1,969 papers in this group. Carbon research follows with 2,132 papers, representing 0.2% of carbon research, while hydrogen research includes 1,466 papers, or 0.3% of its total.
The community comprises 11,330 papers, publishing most frequently in the Journal of Catalysis, the Journal of the American Chemical Society, and Catalysis Letters.
Recent work continues to explore single-atom catalysts and bimetallic systems for selective hydrogenation, including studies on acetylene semi-hydrogenation and nitroarene reduction. Newer papers also investigate photocatalytic hydrogen evolution and the degradation of organic pollutants using engineered oxide and sulfide materials.
