Professor Frederick MacDonnell, a faculty member in the Department of Chemistry and Biochemistry at the University of Texas at Arlington, is supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program to develop multi-electron photocatalysts based on ruthenium. The electronic structure of dinuclear complexes capable of storing multiple redox equivalents to drive proton-coupled electron transfer reactions as a function of pH will be explored. Strategies for both hydrogen generation from sunlight and for electricity generation from sunlight will be investigated.Photocatalysis is one of the few attractive alternatives for maintaining a high standard of living based on continuing energy consumption at the current rate. Finite fossil fuel energy sources are dwindling rapidly, and research plans for converting sunlight to energy, either electrical or in the form of hydrogen gas, are important for future realization of a sustainable economy.

Frederick MacDonnell教授是德克萨斯大学阿灵顿分校化学和生物化学系的教员，他受到无机、生物无机和有机化学计划的支持，开发基于钌的多电子光催化剂。双核配合物的电子结构能够存储多个氧化还原当量，以驱动质子耦合的电子转移反应作为pH值的函数将被探索。将研究从太阳光中产生氢气和从太阳光中产生电力的策略。光催化是少数几个有吸引力的替代方案之一，用于维持基于当前速度的持续能源消耗的高生活水平。 有限的化石燃料能源正在迅速减少，将阳光转化为电能或氢气形式的能源的研究计划对于未来实现可持续经济至关重要。
