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.

在这个由化学系化学合成计划资助的项目中，南卡罗来纳大学化学和生物化学系的理查德·D·亚当斯教授将继续开发合成多金属混合金属簇合物的新方法，该簇合物包含贵重过渡金属如Ru、Rh、Ir和Plu与重金属主族金属如锡、锑和铋的组合。这些新的混合金属簇合物将在载体上转化为双金属和多金属纳米颗粒，作为新一代多相纳米催化剂用于不饱和碳氢化合物的选择加氢和碳氢化合物的氨氧化和部分氧化。重点将放在能够协同工作以执行困难的有机转化和高选择性反应的金属组合上。将这些络合物转化为负载型多金属纳米颗粒，将使新一代多金属纳米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进行研究培训，并提供他们在美国化学工业高科技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具有智力挑战的研究，并解决化学问题。研究经验需要团队合作和独立性，并将激发动力、创造力和领导力。学生将接受有机金属化合物和多相催化剂的合成和表征方面的培训。该项目包括国家和国际合作，将扩大学生的教育和经验。建议的多金属纳米催化剂可能会对依赖于制药、化工和农业中高效有机转化的领域产生影响。
