[EN] Nanolayered molybdenum disulfide cobalt-promoted materials (Co-Mo-S) have been established as chemoselective catalysts for thehydrogenation of nitroarenes under relatively mild conditions. Co-Mo-S catalysts have been ...
[EN] Herein, a general protocol for the preparation of a broad range of valuable N-heterocyclic products by hydrogenation of quinolines and related N-heteroarenes is described. Interestingly, the catalytic hydrogenation ...
Metallic cobalt nanoparticles with surface CoOx patches covered by thin layered carbon (named Co@C) have been directly synthesized by thermal decomposition of Co-EDTA complex. Raman spectra and HRTEM images suggest that ...
[EN] Subnanometric metal species (single atoms and clusters) have been demonstrated to be unique compared with their nanoparticulate counterparts. However, the poor stabilization of subnanometric metal species towards ...

[EN] Preparation of supported metal catalysts with uniform particle size and coordination environment is a challenging and important topic in materials chemistry and catalysis. In this work, we report the regioselective ...
[EN] Sub-nanometric Cu clusters formed by endogenous
reduction of Cu salts and Cu nanoparticles are active
and selective catalysts for C−N, C−C, C−O, C−S, and C−P
bond-forming reactions. Sub-nanometric Cu clusters ...
[EN] Modulating the structures of subnanometric metal clusters at the atomic level is a great synthetic and characterization challenge in catalysis. Here, we show how the catalytic properties of subnanometric platinum ...

[EN] The hydrogenation of CO2 into hydrocarbons promoted by the action of sunlight has been studied on Co nanoparticles covered by thin carbon layers. In particular, nearly 100% selectivity to hydrocarbons is obtained with ...
[EN] Non-noble bimetallic CoW nanoparticles (NPs) partially embedded in a carbon matrix (cow@c) have been prepared by a facile hydrothermal carbon-coating methodology followed by pyrolysis under an inert atmosphere. The ...
[EN] The encapsulation of subnanometric metal entities (isolated metal atoms and metal clusters with a few atoms) in porous materials such as zeolites can be an effective strategy for the stabilization of those metal species ...
