This is a phase II award under the small Business Innovation Research program. In Phase I, the efficient photocatalytic decomposition over titanium dioxide of several organic pollutants in the gas phase under a range of concentrations and conditions was demonstrated. In this work, it will be established whether the pollutants are in fact detoxified and not converted to decomposition products that are still toxic in an environmental sense. The products of the process under various radiation intensities, flow rates, and concentrations are identified. Photoefficiency and product measurements are made for gas streams typical of those found in the field. An attempt to define the useful scope of the gas-phase sensitization method is made.

这是小企业创新研究项目的第二阶段奖励。在第一阶段，在一定的浓度和条件下，二氧化钛在气相上对几种有机污染物进行了有效的光催化分解。在这项工作中，将确定污染物是否实际上被解毒，而不是转化为在环境意义上仍然有毒的分解产物。在不同的辐射强度、流速和浓度下，确定了该过程的产物。光效和产品测量是针对在现场发现的典型气流进行的。试图确定气相敏化法的适用范围。
