奈米二氧化鈦竹炭複合材料對苯、甲苯、甲醛去除之初步研究

Removal of Benzene, Toluene and Formaldehyde by Carbonized TiO2-Bamboo Composites: Preliminary Assessment

摘要


為了推廣台灣地區的竹炭,並提升現有的竹炭機能,銳鈦礦形式的二氧化鈦將和孟宗竹共同燒結,形成奈米二氧化鈦竹炭複合材料,以期藉由結合竹炭的吸附及二氧化鈦的光催化分解,進一步提升竹炭的室內空氣淨化機能。本研究已進行竹炭奈米二氧化鈦複合材料之燒結,並藉由SEM-EDXA實測證明,鈦化物已成功的燒結在竹炭之表面。此外空氣淨化實驗亦證明,在紫外光照射下,可以在60分鐘內,降低密閉室內苯濃度自120ppm至40ppm,同時間竹炭本身僅能降低密閉室內苯濃度自120ppm至80ppm。若只有奈米二氧化鈦粒子與竹炭之混合物,僅能降低密閉室內苯濃度自120ppm至80ppm。而竹炭奈米二氧化鈦複合材料,對淨化甲苯及甲酸亦有同樣的效果。因此本研究已証實竹炭奈米二氧化鈦複合材料之燒結及應用於淨化室內空氣之可行性。

To promote the application of Taiwanese carbonized bamboo, moso bamboo compounded with anatase form of titanium dioxide (TiO2) is conbonized to increase indoor air purification efficiency cause by UV photo-catalysis. SEM-EDXA measurement has verified that TiO2 was successfully compounded on bamboo carbon surface. Under UV radiation, bamboo-carbon/TiO2 composites successfully reduced benzene concentration from 120 ppm to 40 ppm in a closed chamber. In contrast, either bamboo-carbon or bamboo-carbon-TiO2 mixture could only reduce benzene concentration to 80 ppm. Similar trend was exhibited on toluene and formaldehyde removal. Hence this study has confirmed the feasibility of indoor air V℃ removal by carbonized bamboo-TiO2 composites.
