This award by the Inorganic, Bioinorganic, and Organometallic Chemistry Program supports Professor Daniel G. Nocera at the Massachusetts Institute of Technology for the exploration of efficient, and potentially economical, storage of solar energy in the form of chemical bonds. Basic chemical systems will be designed to provide multiple (usually two or four) electron equivalents for the conversion of water or hydrochloric acid and light into high energy products (hydrogen and oxygen or hydrogen and chlorine). Cobalt and rhodium Pacman (tethered diphorphyrin ligands) and Hangman (ligand architectures in which an acid group is positioned in proximity to the metal-hydride site) motifs will be examined electrochemically and photochemically, respectively, for their ability to generate dihydrogen (H2). Cobalt porphyrinogen systems will also be employed for dihydrogen generation. Dr. Nocera has been successful in raising public awareness of the global energy problem and the role that chemistry can play in addressing the energy challenge by appearing on national news, TV, radio programs, and other broadcast venues. He has made significant contributions to curriculum development by producing energy teaching modules for WGBH-TV, the CATALYST Program, and Science News for Kids.

这个奖项由无机，生物无机和有机化学计划支持教授丹尼尔G。诺塞拉在马萨诸塞州理工学院的探索有效的，潜在的经济，储存太阳能的化学键的形式。 基本化学系统将被设计为提供多个（通常是两个或四个）电子当量，用于将水或盐酸和光转化为高能产物（氢和氧或氢和氯）。 钴和铑Pacman（拴系的二卟啉配体）和Hangman（配体结构，其中酸基团位于金属氢化物位点附近）图案将分别进行电化学和光化学检查，以确定其产生二氢（H2）的能力。 钴卟啉原系统也将用于产生二氢。 Nocera博士通过出现在国家新闻，电视，广播节目和其他广播场所，成功地提高了公众对全球能源问题的认识，以及化学在解决能源挑战中的作用。 他为WGBH电视台、CATALYST计划和儿童科学新闻制作能源教学模块，为课程开发做出了重大贡献。
