【 摘 要 】

From an engineering and economic perspective, immobilized TiO2nanocatalysts are preferred in a variety of applications. In this study, TiO2polymer solution was synthesized using ethanol, acetic acid, polyvinylpyrrolidone (PVP), and titanium tetra isopropoxide (TTIP). TiO2solution was deposited on the FTO substrate by electrospinning method to obtain nano-sized layer. Capillary of syringes given a positive DC voltage of 6 kV to produce nanofiber, then annealed at 450 °C for 3 hours. Chlorophyll has obtained from extracted moss through a chromatographic process to used for dye. TiO2nanofiber layer manufactured with varied by time and characterized by UV-Vis and IV-meter. The result exhibited a maximum efficiency of 0,0036% and significant absorption at 350 nm-500 nm wavelength.
