Practical and scalable hydrogenation of nitro compounds using palladium-based nanocatalyst under ambient conditions
Catalytic hydrogenation at ambient conditions represents an essential and practical methodology, which allows for the more convenient access of fine and bulk chemicals. Here, we report Pd-based nanoparticles (Pd-NPs@SiO2) as an efficient catalyst for the hydrogenation of nitroarenes to anilines at atmospheric pressure of hydrogen and at room temperature. This specific Pd-catalyst allows for the hydrogenation of various functionalized and structurally challenging nitroarenes to valuable anilines, which serve as key building blocks and versatile intermediates in chemical, pharmaceutical and agrochemical industries as well as material technologies. These Pd-nanoparticles exhibited excellent stability and can be recycled and reused at least 6 times without any significant drop in the activity. Notably, this ambient hydrogenation process can be scaled up to several grams.
期刊介绍:
Catalysis Today focuses on the rapid publication of original invited papers devoted to currently important topics in catalysis and related subjects. The journal only publishes special issues (Proposing a Catalysis Today Special Issue), each of which is supervised by Guest Editors who recruit individual papers and oversee the peer review process. Catalysis Today offers researchers in the field of catalysis in-depth overviews of topical issues.
Both fundamental and applied aspects of catalysis are covered. Subjects such as catalysis of immobilized organometallic and biocatalytic systems are welcome. Subjects related to catalysis such as experimental techniques, adsorption, process technology, synthesis, in situ characterization, computational, theoretical modeling, imaging and others are included if there is a clear relationship to catalysis.
