CAREER: Chemical and Catalytic Characterization of Dendrimer Templated Bimetallic Nanoparticles

这个CAREER奖在无机、生物无机和有机金属化学项目中支持了三一大学伯特·钱德勒教授的工作，他们使用树突分子介导的封装合成技术来制备支持的双金属纳米颗粒，以控制颗粒的大小和组成。将进行与催化和氢能系统相关的金属纳米颗粒组成的基础研究。聚酰胺胺树状大分子将用于模板化和稳定溶液中的纳米颗粒。为了控制纳米颗粒的组成，将采用两步化学还原法制备树状分子包封的纳米颗粒。催化活性将作为探测双金属纳米颗粒表面性质的一种方法。本科生将参与研究项目，并协助制定相关实验室实验的教学计划。学生在化学培训早期接触纳米技术和多相催化将对劳动力准备产生积极影响。双金属纳米颗粒的研究为使用非均相催化剂的工业过程提供了技术基础。这个项目从复杂的大分子构建块的树状大分子合成转移到衍生纳米颗粒中金属颗粒分布的控制。

This CAREER award in the Inorganic, Bioinorganic and Organometallic Chemistry program supports work by Professor Bert Chandler at Trinity University to prepare supported bimetallic nanoparticles using dendrimer mediated encapsulated synthetic techniques to control the particle size and composition. Fundamental studies of metal nanoparticle compositions that are relevant to catalysis and hydrogen energy systems will be undertaken. Polyamidoamine dendrimers will be used to template and stabilize nanoparticles in solution. Dendrimer encapsulated nanoparticles will be prepared by a two step chemical reduction process in order to control nanoparticle composition. Catalytic activity will be used as a method to probe the surface properties of the bimetallic nanoparticles. Undergraduate students will be integrated into the research project and will help develop instructional plans for related laboratory experiments. Exposure of students to nanotechnology and heterogeneous catalysis early in their chemical training will have a positive effect on workforce preparation.Research in bimetallic nanoparticles contributes to the technology base for industrial processes using heterogeneous catalysts. This project moves from sophisticated dendrimer synthesis with macromolecular building blocks to the control of metal particle distribution in derived nanoparticles.
