The proposed research program aims to accelerate discovery in the area of “advanced environmental and energy material processing” with the ultimate goal of developing new generation, but cost-effective and scalable, environmental and photo-electrochemical energy conversion and storage technologies. This is approached via the innovative integration of aqueous solution process engineering and nanomaterials. There are two thrusts in the proposed research program. The first thrust is the development of altogether new environmental technologies for the immobilization or elimination of toxic pollutants (e.g. As and Se) from industrial effluents via the engineering of “core-shell” or multi-functional (adsorptive-reductive-photocatalytic) nanocomposite structures. Such novel environmental technology will enable the sustainable exploitation of our natural resources and position Canada as world leader in clean resource extraction/processing practices and exportable innovations. The second thrust of this program is focusing on fabrication (aqueous synthesis and electrophoretic deposition) of nanostructured mesoporous electrodes and photocatalysts for lithium-ion energy storage or water disinfection/splitting (hydrogen generation) applications. Li-ion batteries (LIBs) that are behind the explosive proliferation of all kind of portable electronics-2016 marks 25 years since the commercialization of LIBs, they are now called to power our shift as society towards electrification of transportation (EV) and solar energy-derived electricity use and storage. This represents a tremendous growth potential and as such research in this area of energy material processing is highly strategic, well aligned with international cutting edge research directions. The proposed program will provide a fertile ground for training HQP in advanced material processing enabling them to become tomorrow's innovators. Nanostructured materials offer superior functionalities as electrodes in photo-conversion and Li-ion battery storage systems but further improvements both in their performance and fabrication are needed. To this end the proposed program among other will investigate new high-energy and -power cathode materials, such as LiCoPO4 and graphene composites on one hand for building EV LIBs with longer driving range at lower cost; and on the other explore the development of full (UV-Vis-NIR) spectrum TiO2-Cu2ZnSnS4 (CZTS) photocatalysts made from abundant and non-toxic elements that could find applications in water purification or in producing hydrogen via photo-splitting of water. As such the program focuses on water/environment protection and green energy technologies that are at the heart of our sustainable future.

拟议的研究计划旨在加快“先进的环境和能源物质处理”领域的发现，其最终目标是发展新一代，但具有成本效益且可扩展的，环境和照片电气化学能源转换和存储技术。这是通过水溶液工艺工程和纳米材料的创新整合来实现的。拟议的研究计划中有两个推力。第一个推力是通过工程“核心壳”或多功能（Adsorptive-Reductive-reductive-ductive-Rococatalytic）固定污染物（例如AS和SE）的固定或消除有毒污染物（例如AS和SE）的全新环境技术的发展。这种新颖的环境技术将使我们的自然资源和加拿大的可持续剥削能够成为清洁资源提取/加工实践和可出口创新的世界领导者。该程序的第二个推力是针对纳米结构的介孔电子的制造（水合成和电泳沉积），以及用于锂离子储能或水消毒/分裂（氢产生）应用的光催化剂。锂离子电池（LIB）是自LIB商业化25年以来各种便携式电子产品的爆炸性增殖背后的，现在他们被要求为我们的转变提供动力，因为社会向交通运输（EV）和太阳能衍生的电力使用和储存和存储。这代表了巨大的增长潜力，因此在这一能源材料处理领域的研究具有高度战略意义，与国际尖端研究方向保持一致。拟议的计划将为培训HQP进行高级材料处理提供肥沃的基础，从而使他们成为明天的创新者。纳米结构材料具有卓越的功能，作为光转换和锂离子电池存储系统中的电子功能，但需要进一步改进其性能和制造。为此，拟议的计划除其他计划外，将研究新的高能和 - 功率阴极材料，例如一方面以较低的成本来构建较长驾驶范围的EV LIBS，以较低的成本来构建EV LIB；另一方面，探索了由丰富且无毒的元素制成的完整（UV-VIS-NIR）光谱谱Tio2-Cu2Zns4（CZTS）光催化剂，这些光催化剂可以在水纯化中找到应用于水纯化或通过拍摄水的氢生产氢。因此，该计划着重于我们可持续未来的核心水/环境保护和绿色能源技术。
