NON-TECHNICAL DESCRIPTION: This proposal aims to address the need for cleaning the oil spill caused by an explosion of an oil-rig in the Gulf of Mexico. The proposed method is a rapid, straightforward, and economic solution to this problem involving novel, active, ceramic-nano-materials based systems which under exposure to the sun may take advantage of the vast visible spectrum of solar irradiation thus breaking down crude oil in water quickly and effectively into benign constituents that are safe for the environment and for the human and animal welfare. This work will provide new knowledge on how to use solar irradiation to clean-up contamination from organics that would be difficult to remediate by other means in a reasonable time frame with limited resources, and will train students and the public alike in responding effectively to an urgent need to protect the environment and sustain the quality of life.TECHNICAL DETAILS: The proposed research involves oxide-based photoassisted oxidation of organic pollutants (crude oil in salt water) and their decomposition to eco-friendly constituents, through the use of oxide photocatalysts that absorb in the visible range of solar radiation, for the fast and effective cleaning of the oil spill in the Gulf of Mexico. The novel synthesis of 3D nanogrids of the CuO/WO3 system is described in this work. Its targeted use to decompose oil spills simulants (such as benzene in sea water); actual oil spill-containing water samples will be evaluated. Prototyping of self-supported 'photocatalytic screens' for the remediation of large areas of water surface will be also explored. Training of students in state-of-the-art ceramic materials for remediation technologies is an important aspect of this project.

非技术描述：这项提案旨在解决墨西哥湾石油钻井平台爆炸造成的漏油清理需要。提出的方法是解决这一问题的一种快速、直接和经济的解决方案，涉及基于新型、活性、陶瓷-纳米材料的系统，这些系统在阳光下可以利用太阳辐射的广阔可见光谱，从而快速有效地将水中的原油分解为对环境和人类和动物福利安全的无害成分。这项工作将提供关于如何利用太阳辐射来清理有机物污染的新知识，这些污染物很难在有限的资源下用其他方法在合理的时间框架内修复，并将培训学生和公众有效地应对保护环境和维持生活质量的迫切需要。技术细节：拟议的研究涉及基于氧化物的光助氧化有机污染物(盐水中的原油)，并通过使用在可见太阳辐射范围内吸收的氧化物光催化剂将其分解为生态友好成分，用于快速有效地清理墨西哥湾的漏油。本文介绍了CuO/WO_3系三维纳米颗粒的新合成方法。它的目标用途是分解溢油模拟物(如海水中的苯)；将对实际含溢油水样进行评估。此外，还将探索用于修复大面积水面的自承式“光催化滤网”的原型。对学生进行用于修复技术的最新陶瓷材料的培训是该项目的一个重要方面。
