A visible-light-responsive TiO2 with carbonized medium-density fiberboard (c-MDF) was prepared by a one-step preparation method, and its application as an interior building material for decomposition of harmful aromatic volatile organic compounds was evaluated by investigating its toluene decomposition performance. Titanium tetraisopropoxide, cobalt nitrate, and iron nitrate were used as precursor materials for synthesizing metal-doped TiO2, which was then treated on MDF followed by carbonization. After carbonization at 800 °C for 2 h, the crystal structure of metal-doped TiO2 was similar to that of rutile TiO2. Further, a toluene decomposition test was conducted using a modified 20-L chamber system with a commercial fluorescent lamp as the light source. The results revealed that 0.1 mol% metal-doped TiO2/c-MDF completely decomposed toluene in 15 h under visible-light irradiation.

碳化中密度纤维板一步法制备可见光响应二氧化钛降解甲苯

采用一步法制备碳化中密度纤维板(c-MDF)可见光响应TiO2，并通过对其甲苯的考察评价其作为分解有害芳香族挥发性有机化合物的室内建筑材料的应用分解性能。四异丙醇钛、硝酸钴和硝酸铁被用作合成金属掺杂的 TiO2 的前体材料，然后在 MDF 上进行处理，然后进行碳化。在800℃碳化2h后，金属掺杂的TiO2的晶体结构与金红石型TiO2相似。此外，使用改进的 20-L 腔室系统进行甲苯分解试验，使用商用荧光灯作为光源。结果表明，0。
