New Heavy Metals Findings Has Been Reported by Investigators at Academy of Sciences (Palladium-Nanoparticle-Linked Organic Frameworks: Heterogeneous Recyclable Catalysts in Aqueous Medium)

By a News Reporter-Staff News Editor at Life Science Weekly -- A new study on Heavy Metals is now available. According to news originating from New Delhi, India, by NewsRx correspondents, research stated, "4,4'-Biphenylene-bisdiazonium tetrafluoroborate and a palladium salt were reduced simultaneously to result in the formation of palladium atoms and 4,4'-biphenylene biradicals. The palladium atoms underwent clustering forming palladium nanoparticles, whereas the 4,4'-biphenylene biradicals underwent rapid addition reactions to other radicals and also to nanoparticle surfaces."

Our news journalists obtained a quote from the research from the Academy of Sciences, "The resulting product contains palladium nanoparticles covalently linked to an organic framework (PNOF). The effects of different reaction conditions upon metal content as well as on the morphology of the PNOF were studied. The PNOF structure was probed by different experimental techniques. The PNOFs were evaluated as heterogeneous recyclable catalyst in aqueous medium for reduction of 4-nitrophenol and Suzuki coupling reactions."

According to the news editors, the research concluded: "The catalyst exhibited high reactivity even in Suzuki couplings of aryl chlorides."
