The direct photo-decomposition of NOX to N2 and O2 will be investigated , which requires no reducing agent to remove NOX pollution in atmosphere. The CO2 photo-reduction was performed in aqueous solution using TiO2 supported copper catalysts previously. The reaction converted CO2 into methanol under UV irradiation. Maximum methanol yield achieved above 700 μmole/g-catalyst. This project plans to (a) coat photocatalyst on a thin-film and on optical fibers, then assembly an optical-fiber mini-reactor (b) search the optimal conditions of NOx photo-decomposition into N2 and O2; (c) establish a mechanism of photocatalysis in vapor phase and conduct a reaction kinetic model. From the perspective of technology, economy and environment, an optical-fiber reactor can apply to reduce NOX of the flue gas from small-scale boilers, thus reduce NOX pollution in atmosphere. It is feasible and worth to explore.氧化氮光催化分解二氧化鈦觸媒光纖光反應器NOXphoto-decompositionTiO2 catalystoptical-fiber photoreactor
