SBIR PHASE II: Novel Solar Photocatalysts for Air Pollution Control

这个小型企业创新研究第二阶段项目将开发利用太阳能控制空气污染的新型光催化剂。需要成本效益高、能源利用效率高、适合偏远地区、不产生有害副产品的排放控制。理想情况下，这项技术可以迅速商业化，以满足日益紧迫的需求。光催化潜在地具有这些特征，利用紫外光在环境温度下破坏污染物。如果有一种高效的太阳能技术，利用来自太阳的廉价而丰富的紫外线辐射，光催化将特别有吸引力。KSE公司开发了新型光催化剂配方，其活性是传统二氧化钛光催化剂的50倍以上。这样的光催化剂可以大大提高紫外光中太阳辐射的利用效率。在拟议的第二阶段计划中，研究和开发将通过利用这些独特的光催化剂配方来完成，以捕捉太阳辐射的潜力，以破坏空气中有害环境的气体排放。将开发的光催化剂的性能将能够有效利用太阳紫外线辐射，并有效扩大到与实际应用相关的能力。第二阶段计划将针对特定的市场机会，处理选定的挥发性有机化合物和有毒空气污染物。太阳能光催化装置将用于控制土壤和地下水修复、工业排放控制和室内空气质量维护的空气排放。

This Small Business Innovation Research Phase II project will exploit novel photocatalysts for air pollution control using solar energy. Emissions controls are needed which are cost effective, use energy efficiently, are suitable for remote locations, and produce no hazardous by-products. Ideally, the technology could be rapidly commercialized to meet an increasingly pressing need. Photocatalysis potentially has these characteristics, employing ultraviolet (UV) light to destroy contaminants at ambient temperatures. Photocatalysis would be particularly attractive if an efficient solar technology were available, exploiting inexpensive and abundant UV radiation from the sun. KSE, Inc. has developed novel photocatalyst formulations which are over 50 times as active as conventional titania photocatalysts. The efficiency of use of solar radiation in the UV spectrum should be greatly increased by such photocatalysts. In the proposed Phase II program, the research and development is to be completed by exploiting these unique photocatalyst formulations to capture the potential of solar radiation for the destruction of environmentally hazardous gaseous emissions in air. The performance of the photocatalysts to be developed will enable effective utilization of solar UV radiation and efficient scale-up to capacities of relevance to practical applications. The Phase II program will address selected volatile organic compounds and toxic air pollutants, focused on specific market opportunities. Solar photocatalytic units will be used to control air emissions from soil and groundwater remediation, industrial emissions control and indoor air quality maintenance.
