CAREER: Chemical and Catalytic Characterization of Dendrimer Templated Bimetallic Nanoparticles

这一无机化学、生物无机化学和金属有机化学项目的职业奖项支持三一大学的伯特·钱德勒教授的工作，他使用树枝状大分子介导型包覆合成技术来制备支撑型双金属纳米颗粒，以控制颗粒的大小和组成。将开展与催化和氢能系统相关的金属纳米颗粒组合物的基础研究。聚酰胺胺树枝状大分子将用于模板和稳定溶液中的纳米颗粒。为了控制纳米粒子的组成，将通过两步化学还原工艺制备树枝状大分子包裹的纳米粒子。催化活性将作为一种方法来探测双金属纳米颗粒的表面性质。本科生将被整合到研究项目中，并将帮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有助于使用多相催化剂的工业过程的技术基础。这个项目从用大分子构建块合成复杂的树枝状大分子转向控制衍生纳米颗粒中的金属颗粒分布。

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.
