While Canada has significant fresh water reserves (9% of the world's renewable freshwater), the fresh water isnot always available where needed. There exists a huge need for reliable, affordable, and efficient waterpurification devices to provide fresh water for everyday consumption, especially in remote areas. Desalinationis one of the most promising approaches to supply fresh water to deal with the rapidly growing global potablewater demand. Therefore, the industry supporter (New Plateau Technologies) aims at developing low-cost,practical portable handheld water desalination devices. To do so, high-performance and inexpensive membraneto filter salt needs to be developed first. However, the industry supporter does not have the technical orconceptual experience to undertake this task.Thus, the main goal of this six-month Engage project is to capitalize on the existing expertise of Dr. Sun's teamto synthesize three-dimensional (3D) graphene/metal oxide composite filtering membrane, to support NewPlateau Technologies into the fabrication of an efficient handheld water desalinator. Specifically, it includes thesynthesis of 3D graphene-based membrane and its pore size modification, the fabrication of 3D graphene/metaloxide nanocomposite and optimization, and the test for the water filtration performance.

虽然加拿大有大量的淡水储备（占世界可再生淡水的9%），但淡水并不总是在需要的地方可用。存在对可靠、负担得起且高效的水净化设备的巨大需求，以提供用于日常消费的淡水，特别是在偏远地区。海水淡化是最有前途的淡水供应方法之一，以应对快速增长的全球饮用水需求。因此，该行业的支持者（New Plateau Technologies）致力于开发低成本、实用的便携式手持海水淡化设备。为此，首先需要开发高性能且廉价的过滤盐的膜。然而，行业支持者并没有技术或概念经验来承担这项任务，因此，这个为期六个月的Engage项目的主要目标是利用孙博士团队现有的专业知识来合成三维（3D）石墨烯/金属氧化物复合过滤膜，以支持NewPlateau Technologies制造高效的手持式海水淡化器。具体包括3D石墨烯基膜的合成及其孔径改性、3D石墨烯/金属氧化物纳米复合材料的制备及优化、水过滤性能的测试。
