The global energy crisis and environmental problems drive the intense search for a clean and renewable energy source to replace the fossil fuels. The production of clean and renewable energy from inexhaustible solar energy through photocatalytic water splitting and CO2 reduction is a «dream technology» to address the worldwide energy shortage, environmental contamination, and the greenhouse effect. Our current and future research are focused on the design of new efficient sunlight-driven nanostructured photocatalysts for the water splitting to produce hydrogen and the photo-reduction of CO2 into hydrocarbons such as methane and methanol. These products are considered as next-generation energy carriers and sources. Towards such development of efficient sunlight-driven photocatalysts, it is very important to study their efficacy in terms of their ability to perform the redox reactions, which is largely empowered by the increased lifetime of excited charge carriers in the photocatalysts.*******In this context, this proposal aims at acquiring a lifetime-resolved photoluminescence combined with a steady-state spectrometer to study the dynamics of charge carriers, thereby to develop efficient photocatalysts for solar converted fuels and as well as for environmental remediation. It is important to note that we are the first research group at Laval University to study the development of sunlight-driven photocatalysts for solar-converted fuels using sunlight. At present, no such requested equipment system is currently available at Laval University. Thus, the requested equipment is essential for the successful execution and completion of our research projects on the development of efficient photocatalyst******

全球性的能源危机和环境问题促使人们积极寻找一种清洁的可再生能源来替代化石燃料。通过光催化分解水和减少二氧化碳，从取之不尽的太阳能中生产清洁和可再生能源是解决全球能源短缺，环境污染和温室效应的“梦想技术”。我们目前和未来的研究重点是设计新型高效的太阳光驱动纳米结构光催化剂，用于水裂解制氢和CO2光还原为甲烷和甲醇等碳氢化合物。这些产品被认为是下一代能源载体和来源。为了开发高效的阳光驱动的光催化剂，研究它们在进行氧化还原反应的能力方面的功效是非常重要的，这在很大程度上是由光催化剂中激发的电荷载体的寿命增加所赋予的。在这种情况下，该提案旨在获得与稳态光谱仪相结合的寿命分辨光致发光，以研究电荷载流子的动态，从而开发用于太阳能转化燃料和环境修复的高效光催化剂。值得注意的是，我们是拉瓦尔大学的第一个研究小组，研究利用太阳光开发太阳能转换燃料的太阳光驱动光催化剂。目前，在拉瓦尔大学还没有这种要求的设备系统。因此，所要求的设备对于成功执行和完成我们关于开发高效光催化剂的研究项目至关重要 *
