此前有报道称，在紫外光照射下，以二氧化钛为光催化剂，可以将二氧化碳转化为可用作燃料的CO、CH4等。如果这项技术能够实际应用，那么通过利用太阳能将二氧化碳从燃烧转化为燃料，就可以构建一个碳循环系统，这将同时解决全球变暖和化石燃料枯竭的问题。然而，由于产品的燃料浓度太低，这项技术还不可行。为了提高二氧化钛上二氧化碳的浓度，改善二氧化碳的转化性能，采用溶胶-凝胶法和浸渍涂覆法制备了二氧化钛与气体分离膜相结合的膜反应器。利用该反应器对影响膜性能的因素，如浸涂过程中的上升速度等进行了研究。本文报道了该研究的结果。
It was previously reported that CO2could be reformed into CO, CH4, etc., which can be used as fuels, by TiO2as the photocatalyst and under UV radiation. If this technique could be applied practically, a carbon circulation system would then be able to be constructed by reforming CO2from combustion, using solar energy, to fuel, which would solve the problem of global warming and fossil fuels depletion all together. However, the technology is not yet practicable as the fuel concentration of products is too low. To increase the concentration and improve CO2reforming performance on TiO2, a membrane reactor composed of TiO2and gas separation membrane prepared by sol–gel and dip-coating method has been built. Study on the factors influencing membrane performance, e.g. rising speed in the dip-coating process, has been carried out with the reactor. The results of the study are reported in this paper.
