本文采用电弧放电技术在液体介质中对TiO 2纳米粒子进行碳材料改性，制备了TiO 2/Carbon纳米光催化剂。使用浸没在悬浮于乙醇中的TiO 2中的两个石墨电极通过通入20-40 V（10-50 A）的电流进行电弧放电。X射线衍射（XRD）峰形分析表明，从代表结晶TiO 2和碳元素的峰证实了成功的改性。然后，在汞灯照射下，通过评估制造的纳米粒子在甲基叶蓝降解中的光催化活性来进行制造。在60分钟的照射后，TiO 2/碳的光催化活性比原始TiO 2的光催化活性增加了三倍以上。
Herein we modified TiO2 anatase with carbon material using an electrical arc discharge technique in liquid medium to produce a nanoparticle of TiO2/Carbon photocatalyst. The electrical arc discharge was performed using two graphite electrodes submerged in TiO2 suspended in ethanol by passing electrical 20-40 V (10-50 A). X-ray Diffraction (XRD) peak profile analysis shows the successful modification confirmed from the presenting peaks which represent to crystalline TiO2 and carbon element. The fabrication was then followed by the assessment of photocatalytic activity of fabricated nanoparticles in methylebe blue degradation under mercury lamp irradiation. After 60 minutes irradiation, the photocatalytic activity of TiO2/Carbon increased more than three times higher compared to the photocatalytic activity of pristine TiO2.
