| 摘 要： | 设计了能产生波长小于200 nm的真空紫外光化学反应器,通过工作气体氮气进行光强标定表明,其主要产生109 nm,120 nm,149 nm,174 nm波长的光(N原子谱线)。首次在该光化学反应器中进行了CO2光解反应的研究,实验结果表明该实验条件下CO2光解后生成产物CO,当光源电流300 mA时,生成CO的相对量与光源内工作气体的真空度相关。提出了光化学反应器设计时存在的问题、影响因素及考虑因素,为光化学反应器设计放大和操作条件优化提供实验依据和理论思路。

| Abstract: | The vacuum ultraviolet(VUV)photochemical reactor had been designed to produce spectrum which was mainly less than 200 nm in the wavelength range.Atomic spectrum intensity of VUV source was measured by a priorcalibrated VUV spectral detecting system with N_2 chosen as(luminescence) gas.It was found that the main atomic lines wavelength of luminescence gas was(109 nm,)120 nm,149 nm and 174 nm.CO_2 photolysis reaction had been first studied by VUV(photochemical) reactor.Experimental results showed that CO_2 was photolyzed into CO and its amount depended on luminescence gas vacuum of VUV source under 300 mA constant electric current. |
