Through this CAREER award funded by the Chemical Catalysis Program of the Chemistry Division, Professor Alvin A. Holder of the University of Southern Mississippi (USM) will be applying his expertise in the area of catalysis towards the development of photocatalysts. The work targets the important problem of developing improved catalysts capable of photolytic hydrogen generation in aqueous media. It will address the synthesis and characterization of ruthenium(II)-cobalt(II)/cobalt(III) mixed-metal complexes, and investigate their photocatalytic properties using homogeneous schemes. These photocatalytic schemes will exploit reductive quenching pathways that should lead to significantly enhanced catalytic turnovers. In addition, Professor Holder will integrate and bring the chemistry of energy and catalysis in the laboratory to high school students and teachers from the Hattiesburg and surrounding areas, as well as undergraduates and graduate students at USM.This interdisciplinary project will make key contributions to the fundamental knowledge base of converting solar energy to environmentally-friendly, carbon-free, combustible chemical fuels. In addition, the interdisciplinary nature of the proposed work is expected to impact diverse fields, including synthetic chemistry, analytical chemistry, photochemistry, materials chemistry, electrochemistry, and catalysis. The research further involves several teaching points which will be integrated into educational activities at all levels, and involve groups generally underrepresented in science and technology.

通过这个由化学系化学催化计划资助的职业奖，教授阿尔文A。南密西西比大学（USM）的保持器将把他在催化领域的专业知识应用于光催化剂的开发。 本工作针对的重要问题是开发能够在水介质中光解制氢的改进催化剂。 它将解决钌（II）-钴（II）/钴（III）混合金属配合物的合成和表征，并使用均相方案研究其光催化性能。这些光催化方案将利用还原猝灭途径，这将导致显着增强的催化转化率。此外，教授保持器将整合，并把能源和催化在实验室的化学高中学生和教师从哈蒂斯堡和周边地区，以及本科生和研究生在USM.这个跨学科的项目将作出关键贡献的基础知识基础转换太阳能环保，无碳，可燃化学燃料。此外，拟议工作的跨学科性质预计将影响不同的领域，包括合成化学，分析化学，光化学，材料化学，电化学和催化。研究还涉及若干教学点，这些教学点将纳入各级教育活动，并涉及在科学和技术领域代表性普遍不足的群体。
