Multi-walled carbon nanotubes were loaded into titanium dioxide by the hydrothermal method followed by surface modifications using air plasma for enhanced photocatalytic activity. Methyl blue (MB-1) and methylene blue (MB-2) photodegradation under UV and visible light were investigated, resulting that optimal MB-1 and MB-2 degradation was achieved after 90 and 140 min under the UV and was enhanced from 9% to 40% and from 4% to 35% under the visible light. UV photocurrent response was enhanced by three times compared to the precursor because of the plasma treatment, providing higher surface area, lower impedance, bandgap modulation, and more active sites.

通过水热法将多壁碳纳米管加载到二氧化钛中，然后使用空气等离子体进行表面改性以增强光催化活性。研究了甲基蓝（MB-1）和亚甲基蓝（MB-2）在紫外光和可见光下的光降解，结果表明，在紫外光下90和140分钟后，最佳的MB-1和MB-2降解达到最佳，从9提高％到40％，在可见光下从4％到35％。由于进行了等离子体处理，与前驱物相比，UV光电流响应提高了三倍，从而提供了更大的表面积，更低的阻抗，带隙调制和更多的活性位点。
