2019，巴黎七大ITODYS实验室Dr. Lorette Sicard招收CSC公派读博生，研究方向Synthesis of bimetallic nanoparticles and catalytic application for the dehydrogenation of alcohols derived from biomass, 希望有意的同学尽快和她联系，邮箱 lorette.sicard@univ-paris-diderot.fr ED388 – Chimie Physique et chimie analytique de Paris centre Synthesis of bimetallic nanoparticles and catalytic application for the dehydrogenation of alcohols derived from biomass Lorette SICARD Laboratoire ITODYS – Equipe NE2C 15 rue Jean-Antoine de Baïf – 75205 Paris Cedex 13 Université Paris Diderot – USPC SET : Sciences Exactes et Technologies Bimetallic nanoparticles (NPs) have received growing interest for a wide range of applications.1 By varying the composition and size of clusters of nanoalloys, a fine control of the electronic state can be obtained and synergetic effects have been reported for different catalytic reactions. Among other reactions, the acceptorless dehydrogenation of alcohols, promoted by metals such as Ru, Co and Cu, is important as it allows preparing valuable ketones and aldehydes from biomass-derived compounds with molecular hydrogen as the only side-product. Recently, we reported that Co nanorods are very efficient catalysts, with a very high chemoselectivity for the dehydrogenation of secondary alcohols2 and that the presence of Ru at the surface contributed to stabilize the catalytic activity during recycling.3 This is an incentive to prepare alloys and to test them towards the dehydrogenation of different alcohols. The work will focus on the preparation of Co-Ru, Ru-Cu and Co-Cu nanostructures with different compositions by soft chemistry and the evaluation of their catalytic activity and possible synergetic effects. The possibility to improve the stability of the NPs towards recyclability by coating the nanostructures with a porous carbon or silica shell will also be examined. 1 K.D. Gilroy et al., Chem.

要骂人了，新模版改版就是要淡化问题凝练这种虚的东西，结果有个评委还在说凝练得不够
