본 연구에서 HCl을 처리하지 않고 혹은 HCl 처리한 표면 처리된 MWCNT 및 TNB를 이용하여 <TEX>$C/TiO_2$</TEX> 복합체를 제조하였다. XRD 결과 값으로부터 모두 시료에 한 가지 결정 구조 즉 anatase형을 존재하고 있음을 알 수 있었다. SEM 사진으로부터 <TEX>$TiO_2$</TEX> 입자와 CNT는 균일하게 분포하고 있음을 알 수 있었다. EDX 결과에서, 모두 시료에 C, O, Al와 Ti 피크를 볼 수 있으며, 특히 시료 CT에 있는 C와 Ti의 함량은 시료 HCT에 있는 것보다 많게 나타났다. 마지막으로, <TEX>$C/TiO_2$</TEX> 복합체는 <TEX>$TiO_2$</TEX>보다 더 좋은 광촉매 특성을 가지고 있음을 알 수 있었다.
C/TiO2 composites were prepared with surface modified MWCNT sequentially after HCl treatment and TNB as titanium source. There is a single crystal structure which is anatase in all of the samples from the data of XRD. The SEM microphotographs of C/TiO2 composites show that the TiO2 particles were well mixed with the CNT. There are C, O and Al with strong Ti peaks in all samples from EDX results, and it also shows that the sample CT has much more amount of C and Ti content than that of sample HCT. Finally, the photocatalytic activities for the C/TiO2 composites have more effective than that of pristine TiO2.
