Every hour the Earth's surface receives more energy from the sun than the world's current annual energy consumption. This radiative energy can potentially become the ideal alternative to fossil fuels and a solution to the energy shortage and environmental problems facing all countries in the world. Currently, the major challenge for solar energy utilization is the energy-efficient and cost-effective conversion of sunlight to appropriate forms of energy such as electricity or heat, as well as the storage of that energy. In the proposed research, new nano-composites will be synthesized, characterized, and their usefulness as photocatalysts in solar-powered water disinfection applications will be tested under conditions compatible with the efficient operation of solar cells. A variety of base compounds, doping agents, and preparation parameters will be examined in order to optimize the novel catalysts. Different photoreactor designs will be developed and tested to maximize the efficiency of these new systems. The coupling of photovoltaic and photocatalytic steps in a newly designed system will also be experimentally studied and applied to the high efficiency production of electricity and sanitary hot water. The expected outcome of the research project include the creation of new photocatalysts that are active under sunlight, and the development of a cost- and energy- efficient photoreactor system. These results will significantly contribute to the solution of key energy and environmental problems facing Canadians and people around the world. In addition, this multi-disciplinary research project will be ideal for the training of HQP.

地球表面每小时都会从太阳中获得更多的能量，而不是世界当前的年度能源消耗。这种辐射能量可能成为化石燃料的理想选择，也可以解决世界上所有国家面临的能源短缺和环境问题的解决方案。当前，太阳能利用的主要挑战是将阳光转换为适当的能源形式（例如电力或热量）以及该能源的储存的能源效率和成本效益。在拟议的研究中，将合成，表征新的纳米复合材料，并在与太阳能电池有效运行的条件下，将测试它们作为太阳能水消毒应用中光催化剂的有用性。为了优化新型催化剂，将检查各种基本化合物，掺杂剂和制备参数。将开发和测试不同的光反应器设计，以最大程度地提高这些新系统的效率。新设计的系统中光伏和光催化步骤的耦合也将进行实验研究，并应用于电力和卫生热水的高效产生。研究项目的预期结果包括创建在阳光下活跃的新光催化剂，以及成本和节能的光反应器系统的发展。这些结果将极大地有助于解决加拿大人和世界各地人民面临的关键能源和环境问题。此外，该多学科研究项目将是HQP培训的理想选择。
