This proposal involves the focused effort by this team to translate the results of current NSF funded research on visible light photocatalysts for water remediation (nanogrids) into actual products for the remediation market. Nanogrids -i.e. miniaturized "fishing nets"-like self-supported mats that float on water- of these nanocatalysts rapidly decompose crude oil and other contaminants using solar irradiation, and fast and at low cost turn them into water, carbon dioxide, and biodegradable organics. Therefore, these nanogrids may clean oil spills effectively, whether these are near the seashore or in the middle of the ocean; at a refinery, or at a water cleaning facility. The proposed project addresses the scalability of the synthesis method used for the nanogrids and aims to produce a prototype of the nanogrids technology for use in remediating oil pollution. The photocatalytic nanogrids tehnology that this team are developing involve green photochemistry; uses the whole spectrum of the solar irradiation (unlike the industrial catalysts that respond to UV-light only) thus providing significantly improved catalytic efficiency; it responds to various types of contaminants (thus enabling diverse uses); and offers complete oxidation of hydrocarbons into ecofriendly species. The potential flexibility of process conditions (contact time with pollutant, floatability, recovery, reuse), the fact that it responds to an urgent need for economic water remediation technologies, and its potential to go from the lab to the marketplace within months, make the nanogrids a breakthrough nanotechnology worth exploring further towards commercialization. Oil derivatives are among the most dangerous compounds for the environment. The photocatalytic nanogrids technology provides a means to contain and clean oil contamination, especially in water, in a most cost-effective and ecofriendly manner. While current photocatalysts are activated by only about 2% of the solar irradiance, the nanogrids respond to radiation from the full solar spectrum. And solar power is free. Apart from water remediation, immediate uses of the nanogrids technology are envisioned in filtration, as well as in biomedical and pharmaceutical industries. Scaling-up the nanomanufacturing process will provide significant benefits in terms of reducing the cost and increasing the availability of the nanogrids to be used in actual commercial products. Commercializing this technology will create new jobs, will provide the opportunity to train the workforce in using nanotechnology and nanomanufacturing to make real and versatile market products, and it will benefit the environment and the human welfare.

该提案涉及该团队的重点工作，将当前NSF资助的用于水修复的可见光光催化剂（纳米网格）研究成果转化为修复市场的实际产品。 这些纳米催化剂的纳米网格-即小型化的“渔网”-像漂浮在水上的自支撑垫-使用太阳辐射快速分解原油和其他污染物，并快速且低成本地将它们转化为水，二氧化碳和可生物降解的有机物。因此，这些纳米网格可以有效地清洁石油泄漏，无论这些泄漏是在海岸附近还是在海洋中;在炼油厂还是在水清洁设施。拟议的项目解决了用于纳米网格的合成方法的可扩展性，并旨在生产用于修复石油污染的纳米网格技术原型。 该团队正在开发的光催化纳米网格技术涉及绿色光化学;使用太阳辐射的整个光谱（不像工业催化剂只对紫外光做出反应），从而显着提高催化效率;它对各种类型的污染物做出反应（从而实现多样化用途）;并将碳氢化合物完全氧化为环保物种。工艺条件的潜在灵活性（与污染物的接触时间，可漂浮性，回收，再利用），它对经济水修复技术的迫切需求做出反应的事实，以及它在几个月内从实验室走向市场的潜力，使纳米网格成为一种突破性的纳米技术，值得进一步探索商业化。石油衍生物是对环境最危险的化合物之一。光催化纳米网格技术提供了一种以最具成本效益和生态友好的方式控制和清洁油污染的方法，特别是在水中。虽然目前的光催化剂仅被约2%的太阳辐照度激活，但纳米网格对来自全太阳光谱的辐射做出响应。太阳能是免费的。除了水的修复，纳米网格技术还可以直接用于过滤，以及生物医学和制药行业。扩大纳米制造过程将在降低成本和增加用于实际商业产品的纳米网格的可用性方面提供显着的好处。这项技术的商业化将创造新的就业机会，将提供机会，培训劳动力使用纳米技术和纳米制造，使真实的和多功能的市场产品，它将有利于环境和人类福利。
