中文摘要：

作为装饰材料，镁氯氧化物水泥被用作一个光催化剂支持者在室内净化污染物质。由于激活的碳(交流) 的优秀吸附性质， photocatalytic composties， TiO ₂/AC, 被准备并且介绍底层进多孔的镁氯氧化物水泥(PMOC ) 到合成一种 photocatalytic 似水泥的材料(脉冲编码调制) 。最佳的合成过程被气体估计用色层法分离，用象目标的甲苯。由比较甲苯纯化和彻底的分解的观点，为 TiO ₂/AC composites 的最佳的集体比率是 4/25，和热处理到在排除的 350 e 的 TiO ₂/AC 样品，这能被发现。我们验证了新 Baveno VI 建议一吗？？

英文摘要：

As a decorative material, magnesium oxychloride cement was used as a photocatalyst supporter to purify the pollutants indoors. Due to excellent adsorption properties of activated carbon（AC）, the photocatalytic composties, TiO2/AC, were prepared and introduced into the porous magnesium oxychloride cement（PMOC） substrate to composite a sort of photocatalytic cementitious material（PCM）. The optimal composite processes were assessed by gas chromatograph, using toluene as the target. By comparing the perspective of toluene purification and thorough decomposition, it can be found that the optimal mass ratio for TiO2/AC composites is 4/25, and the heat treatment to TiO2/AC sample at 350 ℃ can play the optimal synergetic role of adsorbents in photocatalytic process. The synergistic effect of TiO2, AC and magnesium oxychloride cement（MOC） was also evaluated by gas chromatograph. One-take molding process was adopted to introduce the TiO2/AC into PMOC substrate, and its optimal mass fraction was 4 wt%, while the appropriate density of substrate was 0.35 g/cm3. Toluene degradation showed that the prepared PCM can degrade pollutants efficiently. The appropriate treatment process of TiO2/AC, mass of TiO2/AC, substrate density, and stable pore structure should be coordinated to maximize the adsorption-photodegradation performance. The combination of photocatalytic materials, adsorbents, and building materials provided a new idea for the application of photocatalysis.
