The efficacy of photocatalytic oxidation was relative to the number of dip-coated plate, which 2 and above plates was superior to one plate, and also vertical plane to the light source was more efficient than parallel plane. The reaction rate constant showed the color removal decreased as initial MB concentration was raised. As for efficiency of catalyst durability, it was found that TiO2 dip-coated stainless steel plate performed 95% color removal at 5ppm MB even after 4 times repeated usage, which showed favorable durability. However, when the concentration up to 10 ppm, the color removal decreased as the used counts was raised.

脱色率和钢网片数有关，钢网片数超过2片以上时，其光催化效能优於单片者；光催化效能与钢网摆放方式或光源入射的角度有关，与光源垂直摆放的脱色率优於与光源平行摆放者；由反应速率常数得知，反应物之脱色率随著反应物初始浓度的提升而递减：在耐用性方面，亚甲基蓝5ppm在重覆使用四次后，其六个小时脱色率皆维持95%，显示自制光触媒钢网之耐用性颇佳，若将反应物浓度提升至100ppm，其脱色率随著使用次数之增加而递减。
