(1)single sites to complete hydrogenation.The Ir_(1+NPs)/CMK catalyst exhibits much higher reactivity with turnover frequency of 7,800 h^(1)than those counterpart Ir_(1)/CMK and IrNPs/CMK catalysts,and is 20,000 times higher activity of commercial Ir/C benchmark catalyst for hydrogenation...
density functional theory (DFT) calculations confirm the improved electronic conductivity and facile energy barrier contributed by the incorporated Ir single atoms, resulting in a high OER catalytic activity. Moreover, the preparation of Ir-Co3O4can be ...
Photoredox-catalysis-mediated by a ruthenium catalyst as the single-electron transfer agent is useful for the 1,2-difunctionalization of alkenes.114 Terminal and internal alkenes react with Umemoto’s reagent (S-trifluoromethyldibenzothiophenium triflate), in the presence of nitriles and catalytic amoun...
Single-atom catalysts(SACs) with maximal metalatom utilization, homogeneous and tailorable active sites have emerged as promising catalyst candidates, where the local coordination structures of the metal atoms in SACs largely determine the reaction kinetics. Previous design strategies of constructing strong...
2) opened the door for oxidative addition reactions, a process fundamental to useful reactions. For example, Crabtree's catalyst, a homogeneous catalyst for hydrogenation reactions.[38][39] Skeletal formula presentation of a chemical transformation. The initial compounds have a C5H5 ring on their to...

Here, a novel dual-core drive transfer hydrogen heterogeneous catalysts Ir@CNT@ADH were developed by sequentially immobilizing the NADH-dependent alcohol dehydrogenase ADH and high active NADH-regenerated catalyst Pyren-Ir1 on the surface of carbon nanotubes. Two pyrene-functionalized Ir-complex, Pyrene...
In summary, we developed a novel single-atom Ir incorporated into Ni(Fe) oxyhydroxides catalyst for OER, by utilizing the surface reconstruction of nanoporous Ni (Fe) phosphides. The as-prepared np-Ir/NiFeO catalyst exhibited an outstanding OER performance in alkaline aqueous solutions, showing ...
