4) sedimentary overlap
沉积超覆
1.

3.
The results showed that when NTA was treated in CO at high temperature,the carbon doping in product TiO2 did not appear,only carbon deposition on TiO2 appeared;the BET areas of the products decreased markedly with the increase of treating temperature;The transformation temperature from anatase to rutile for TiO2 obtained by CO treatment was much lower than that obtained by air treatment.
结果表明:NTA经CO高温处理后,样品未发生C掺杂,只有碳沉积发生;随着处理温度的升高,样品的比表面积大幅下降,与NTA在空气中焙烧处理相比,由锐钛矿向金红石TiO2转变的温度提前;CO处理后产物对C3H6均未表现出可见光催化性能,但具有紫外光催化活性,随着在CO气氛中处理温度的升高,紫外光催化活性降低。

补充资料：化学气相沉积碳纤维
分子式：
CAS号：
性质：又称化学气相沉积碳纤维。指特定混合气在高温下热解沉积在催化剂微粒上成长成碳纤维。直径几微米，强度高达其理论值的1/4，模量高达1000GPa，电阻率0.8～1.5×10-4Ω·cm，抗氧化和耐腐蚀性优良。制法是将碳氢化合物的蒸气与铁、镍、硫及其氧化物或盐类微粒等催化剂源和氢氧接触，在1100℃下热解使碳沉积并在催化剂上成长，再经石墨化处理而得，也可制成弹簧状。用于先进复合材料的增强剂和弹簧等。
