Synthesis of Polynuclear Transition Metal - Heavy Main Group Metal Carbonyl Complexes for Use as Next-Generation Multimetallic Heterogeneous Nano-Catalysts

南卡罗来纳大学化学与生物化学系的Richard D. Adams教授将继续开发合成多金属混合金属团簇配合物的新方法，该配合物含有贵重过渡金属（如钌、铑、铱和铂）与重主族金属（如锡、锑和铋）的组合。这些新的混合金属团簇配合物将在载体上转化为双金属和多金属纳米颗粒，用作新一代非均相纳米催化剂，用于不饱和烃的选择性加氢以及碳氢化合物的氨氧化和部分氧化。重点将放在金属的组合，可以协同作用，以执行困难的有机转化和反应与高选择性。将这些配合物转化为支撑的多金属纳米颗粒将使新一代多金属纳米团簇在碳氢化合物的催化转化和反应中得到应用。更广泛的影响包括对研究生和本科生的研究培训，并为他们提供在美国化学工业的高技术专业环境中竞争所需的经验。他们将学习制定和执行有用的和智力上具有挑战性的研究，并解决化学问题。研究经验将需要团队合作和独立，并将激发动力，创造力和领导能力。学生将学习有机金属化合物和多相催化剂的合成和表征。该项目包括国内和国际合作，将扩大学生的教育和经验。提出的非均相多金属纳米催化剂可能对依赖于制药、化学和农业工业中有效有机转化的领域产生影响。

In this project funded by the Chemical Synthesis Program of the Chemistry Division, Professor Richard D. Adams of the Department of Chemistry and Biochemistry at the University of South Carolina will continue to develop new procedures for the synthesis of multimetallic mixed-metal cluster complexes containing combinations of precious transition metals, e.g. ruthenium, rhodium, iridium and platinum with heavy main group metals, such as tin, antimony and bismuth. These new mixed-metal cluster complexes will be converted into bi- and multimetallic nanoparticles on supports to be used as new next-generation heterogeneous nanocatalysts for the selective hydrogenation of unsaturated hydrocarbons and the ammoxidation and partial oxidation of hydrocarbons. Emphasis will be placed on combinations of metals that can function cooperatively to perform difficult organic transformations and reactions with high selectivity. The conversion of these complexes into supported multimetallic nanoparticles will allow access to a new generation of multimetallic nanoclusters for applications in catalytic transformations and reactions of hydrocarbons. The broader impacts involve training of graduate and undergraduate students in research and to provide the experience required for them to compete in the highly technological professional environment of the U. S. chemical industry. They will learn to formulate and perform useful and intellectually challenging research and to solve chemical problems. The research experience will require both teamwork and independence, and will stimulate motivation, creativity and leadership. Students will be trained in the synthesis and characterization of organometallic compounds and heterogeneous catalysts. The project includes national and international collaborations that will broaden the education and experience of the students. The proposed heterogeneous multimetallic nanocatalysts may have an impact on areas that rely on the efficient organic transformations within pharmaceutical, chemical, and agricultural industries.
