Abstract
En 中文
In order to optimize the performance of g-C3N4for environmental and energy-related applications, its modification is highly essential. In this study, CN was modified with TiO2viaa wet-chemical method to fabricate its composite (i.e. TiO2/CN). Various characterization techniques such as UV spectroscopy, FT-IR, SEM, EDX and TGA/DSC were employed to investigate the physicochemical properties of the as-synthesized TiO2/CN. The as-synthesized samples were employed in supercapacitor and photocatalytic applications. The TiO2/CN nanocomposite electrode achieved a notable specific capacitance of 287.7 F/g in supercapacitor applications. Moreover, the TiO2/CN revealed superior activity for degradation of Basic Blue 3 dye (BB3) i.e. degraded 99.68% of the BB3 dye in 240 min. Similarly, the effect of different parameters including time, dye concentration, temperature, pH, dose, and some oxidants was also studied. The composite revealed favorable kinetics of both PFO and PSO and was found stable with good recycling ability up to 5 cycles.
