Photocatalytic disintegration is a novel approach to eliminate pollution. The method utilizes the semiconductor titanium dioxide to degrade organic molecules in the presence of ultraviolet (UV) light. In this study, it is shown how the capabilities of several types of catalyst designs degrade the non-polar substance diesel fuel and the polar substance methylene blue. The floating design of foam glass coated with titanium dioxide could reduce the concentration of diesel fuel by 329 mg/L in 16 h; the submerged designs for coated glass fiber and coated steel grit could reduce methylene blue concentration by 96.6% after 4 h and 99.1% after 6 h, respectively. It could be shown that photocatalysis is a promising cost- and energy-efficient method for managing air and water pollution. It can be established as a low-technology method without requiring the use of a conventional source of energy, given an adequate amount of sun hours, or as an additional cleaning stage in water treatment plants using UV-LEDs.

光催化分解是一种消除污染的新方法。该方法利用半导体二氧化钛在紫外线 (UV) 光的存在下降解有机分子。在这项研究中，展示了几种类型的催化剂设计的能力如何降解非极性物质柴油燃料和极性物质亚甲蓝。涂有二氧化钛的泡沫玻璃漂浮设计，16小时内可降低柴油浓度329mg/L；涂层玻璃纤维和涂层钢砂的浸没式设计可分别在 4 小时后和 6 小时后将亚甲蓝浓度降低 96.6% 和 99.1%。可以证明，光催化是一种有前途的成本和能源效率高的空气和水污染管理方法。
