SBIR Phase I: Novel Solar Photocatalysts for Air Pollution Control

这个小企业创新研究一期项目利用新型光催化剂控制空气污染。需要进行技术创新，以有效管理工业作业产生的稀释空气污染源和修复受污染的地下水和土壤。排放控制需要具有成本效益，有效利用能源，适合偏远地区，并且不产生有害副产品。光催化潜在地具有这些特性，利用紫外线（UV）光在环境温度和压力下破坏化合物。如果有一种有效的太阳能技术，利用太阳廉价而丰富的紫外线辐射，光催化将特别有吸引力。迄今为止，太阳能光催化还没有足够的效率或有效的大规模采用。KSE公司，这个提议的公司，已经开发了一种新型的光催化剂配方，其活性是传统二氧化钛光催化剂的50倍。这种光催化剂可大大提高对太阳W光谱辐射的利用效率。第一阶段研究的目标是确定利用这些独特的光催化剂配方的技术可行性，以捕获太阳辐射的潜力，以破坏空气中有害环境的气体排放。待开发的光催化剂的性能将能够有效地利用太阳紫外线辐射，并有效地扩大到与实际应用有关的能力。第一阶段将重点关注氯化挥发性化合物（CVOC）和甲苯作为模型化合物，第二阶段将扩展到工业有害排放的全部范围。预计到2000年，美国的环境控制设备市场的销售额将增长到16亿美元。待开发的太阳能光催化空气污染控制产品将在该市场上得到广泛应用。最初，将安装太阳能光催化装置来控制土壤和地下水的空气排放，因为它具有优越的经济效益和对偏远地区的适应性。未来的产品将解决工业尾气排放控制和室内空气质量维护。

9560558 Kittrell This Small Business Innovation Research Phase I project exploits novel photocatalysts for air pollution control. Technological innovation is required to effectively manage dilute sources of air pollution from industrial operations and remediation of contaminated groundwater and soils. Emissions controls are needed which are cost effective, use energy efficiently, are suitable for remote locations, and produce no hazardous by-products. Photocatalysis potentially has these characteristics, employing ultraviolet (UV) light to destroy chemical compounds at ambient temperatures and pressures. Photocatalysis would be particularly attractive if an efficient solar technology were available, exploiting inexpensive and abundant UV radiation from the sun. To date, solar photocatalysis has not been sufficiently efficient or effective for large scale adoption. KSE, Inc., the proposing firm, has developed novel photocatalyst formulations which are about 50 times as active as conventional titania photocatalysts. The efficiency of use of solar radiation in the W spectrum should be greatly increased by such photocatalysts. The objective of the Phase I research is to establish the technical feasibility of 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. Phase I will focus on chlorinated volatile compounds (CVOC's) and toluene as model compounds, with extension in Phase II to the full spectrum of industrial hazardous emissions. The environmental control equipment market in the United States is forecast to grow to sales of $1.6 billion by the year 2000. The solar photocatalytic air pollution control products to be developed will find broad application in that marketplace. Initiall y, solar photocatalytic units will be installed to control air emissions from soil and groundwater remediation due to the superior economics and ready adaptability to remote locations. Future products will address industrial tailpipe emissions control and indoor air quality maintenance.
