This Small Business Innovation Research (SBIR) Phase I project proposes to establish the technical and economic feasibility of a novel photocatalytic technology to inactivate air-borne surrogate bacterial spores representative of Bacillus anthracis (anthrax bacteria). The technology is to be incorporated into circulating air ducts of buildings, providing protection against introduction of anthrax into central air systems by a terrorist act. The investigators have previously developed a new class of photocatalysts that are orders of magnitude more active for organic compound oxidation than the traditional titania. This new class of photocatalysts will be adapted for use in anthrax spore destruction. The program will utilize photocatalyst composition studies to tailor a superior photocatalyst for this application, to be followed by reactor studies of the bactericidal efficacy of the new photocatalysts, and a competitive cost analysis of the technology relative to other alternatives for maintenance of indoor air quality. The immediate commercial application of this project is in the area of homeland security. The proposed technology will protect against the threat of introduction of lethal anthrax spores into central air systems.

该小型企业创新研究（SBIR）第一阶段项目提出建立一种新型光催化技术的技术和经济可行性，以消除代表炭疽芽孢杆菌（炭疽细菌）的空气传播的替代细菌孢子。该技术将被纳入建筑物的循环空气管道，防止恐怖主义行为将炭疽引入中央空气系统。研究人员先前已经开发出一类新的光催化剂，其对有机化合物氧化的活性比传统的二氧化钛高出几个数量级。这种新型的光催化剂将适用于炭疽孢子的破坏。该计划将利用光催化剂成分的研究，为这种应用定制一种上级光催化剂，然后进行新的光催化剂的杀菌功效的反应器研究，并对该技术相对于其他替代品的竞争力进行成本分析，以维持室内空气质量。该项目的直接商业应用是在国土安全领域。 拟议中的技术将防止致命的炭疽孢子进入中央空调系统的威胁。
