The Powering the Planet (PP) Chemical Bonding Center focuses on one of the "Grand Challenges" for the 21st Century: the efficient, and ultimately economical, conversion of solar energy into stored chemical fuels. PP efforts will focus on developing the components for a solar water splitting system. These components are: (i) a membrane-supported assembly that captures sunlight and then efficiently separates and transports charge, (ii) a two-electron catalyst that reduces water to hydrogen, and (iii) a four-electron catalyst that oxidizes water to oxygen. This interdisciplinary effort will involve semiconductor materials, polymeric and inorganic membranes, synthesis, theory, and mechanistic chemistry. The basic science pursued in PP will provide the foundation for future carbon-neutral energy technologies. PP will train a diverse and talented pool of students in the technical skills needed for the solution of this critical challenge. PP will incorporate underrepresented groups through partnering with specific undergraduate institutions and providing broad access to PP research scientists through both direct and virtual (videoconference) interactions. Outside of the laboratory, PP participants will help develop innovative curricula for high school, undergraduate, and graduate students. PP researchers will raise the public's awareness of the challenges of the energy problem, how solar energy can contribute to its solution, the nature of the fundamental scientific challenges in developing a water-splitting device, and the impact of PP research through public lectures, national TV and radio programs. Further, PP PIs will work with several major business leaders and companies in the U.S. to help them develop a position that contributes positively to the energy and sustainability challenges confronting our planet.

为地球提供动力（PP）化学键合中心专注于21世纪的“重大挑战”之一：将太阳能高效且最终经济地转化为储存的化学燃料。PP的工作将集中在开发太阳能水分解系统的组件上。这些组成部分是：（i）捕获阳光然后有效分离和传输电荷的膜支撑组件，（ii）将水还原成氢的双电子催化剂，和（iii）将水氧化成氧的四电子催化剂。这一跨学科的努力将涉及半导体材料，聚合物和无机膜，合成，理论和机械化学。PP所追求的基础科学将为未来的碳中和能源技术提供基础。 PP将培养多样化和有才华的学生，掌握解决这一关键挑战所需的技术技能。PP将通过与特定的本科院校合作，并通过直接和虚拟（视频会议）互动，为PP研究科学家提供广泛的访问机会，来纳入代表性不足的群体。在实验室之外，PP参与者将帮助开发高中，本科和研究生的创新课程。PP研究人员将提高公众对能源问题挑战的认识，太阳能如何有助于解决问题，开发水分解装置的基本科学挑战的性质，以及通过公共讲座，国家电视和广播节目进行PP研究的影响。此外，PP PI还将与美国的几家主要商业领袖和公司合作，帮助他们发展自己的地位，为我们地球面临的能源和可持续性挑战做出积极贡献。
