Direct formation of carbon supported Pt nanoparticles by plasma-based technique

Publication date: 15 November 2019Source: Materials Letters, Volume 255Author(s): HuJun Xu, ChaoHong He, LiangLiang Lin, Jie Shen, ShaoMing ShangAbstractA conceptually new method based on plasma-electrochemical technique is demonstrated for the one-step synthesis of carbon supported Pt nanoparticles. Ethanol and chloroplatinic acid aqueous solution were used as the carbon and platinum sources, respectively, without involving any extra chemicals. Results showed that crystalline Pt nanoparticles as well as amorphous nanocarbons could be simultaneously generated to form Pt/C nanocomposites under the plasma impact, where the Pt content can be tuned by regulating the chloroplatinic acid concentration. Moreover, the formation mechanisms of the C and Pt/C nanocomposites in the studied system were discussed. The demonstrated simple, unique, one-pot and environmentally-benign process should bring interest in this emerging nanofabrication technique.Graphical abstract
