A hybrid photocatalyst based on anatase TiO2 was designed by doping TiO2 with sulfur and incorporating reduced graphene oxide (TiO2-S/rGO hybrid), with an aim to narrow the band gap to potentially make use of visible light and decrease the recombination of excitons, respectively. This TiO2-S/rGO hybrid was successfully synthesized using a one-pot hydrothermal method via single-step reaction. The structure and morphology of the TiO2-S/rGO hybrid catalyst was carefully characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS). Its photocatalytic reactivity was evaluated by the degradation of methyl blue. The results showed that both the doping of sulfur and the introduction of rGO worked as designed, and the TiO2-S/rGO hybrid exhibited high photocatalytic activity under simulated sunlight. Considering both the facile and scalable reaction to synthesize TiO2-S/rGO hybrid, and its excellent photocatalytic performance, such TiO2-S/rGO hybrids are expect to find practical applications in environmental and energy sectors.

“…In addition, the diffraction peaks denoted as “A” correspond to the (101), (004), (200), (105) and (211) planes. These correspond to the anatase TiO 2 , according to the JCPDS file 21–1272 . This means that the TiO 2 IL is successfully formed from the TiO 2 sol–gel solution without the sintering process.…”

An interfacial layer (IL) between the CdS quantum dot (QD) and dye is necessary in the CdS-dye co-sensitized solar cell (CSC) to prevent the corrosion of CdS and the damage of electrolyte. In this study, the simple method of using a TiO 2 sol-gel solution is suggested to fabricate the IL. An air exposure process after dipping into the TiO 2 sol-gel solution facilitates formation of the anatase TiO 2 thin film. To confirm the effect of TiO 2 IL, the performance of CdS-dye CSC is analyzed and compared to the conventional CdS QD sensitized solar cell (QDSC). The formed TiO 2 IL effectively prevents the corrosion of CdS and the damage of electrolyte. In addition, this suppresses the electron recombination from the CdS to the electrolyte, resulting in the enhanced electron transport at the TiO 2 /CdS QD-dye/electrolyte interface. As a result, the overall photovoltaic performance is much increased from 1.33% to 2.77%, compared to the conventional CdS QDSC.

“…The characteristics peaks at 2θ ≈ 18.5°, 20.2°, 26.8°, and 39.3° corresponds to (100), (110), (022), and (211) reflections of crystalline plane of PVDF–HFP . The crystalline planes of TiO 2 and ZnO are also noted in Figure (a). It is observed that the peak intensity of PVDF–HFP polymer matrix decreases with addition of IL and further decreases with addition of nanoparticles.…”

Poly(vinylidene fluoride‐co‐hexafluoropropene) (PVDF–HFP)‐based polymer electrolytes embedded with 1‐ethyl‐3‐methylimidazolium tetrafluoroborate ioniliquid have been synthesized to improve the ionic conductivity. Electric double‐layer capacitors (EDLC) have been prepared using the synthesized polymer electrolytes. Inorganic oxide fillers (5 wt %) such as titanium dioxide (TiO2) and zinc oxide (ZnO) nanoparticles have been added to polymer electrolytes to compare the electrochemical behavior of the fabricated EDLC. The intrinsic dielectric constant of nanoparticles contributes in ionic dissociation which enhances ionic conductivity of electrolytes and also controls the specific capacitance of the EDLC fabricated with these electrolytes. Physicochemical properties of polymer nanocomposites have been investigated using X‐ray diffraction, differential scanning calorimetry, and Fourier transform infrared analysis, which confirms decrease of crystalline phase in host polymer PVDF–HFP. The maximum voltage stability is obtained for TiO2‐based polymer electrolyte. The high specific capacitance as well as high energy density is obtained for the EDLC cell with TiO2‐based polymer electrolyte compared to EDLC with ZnO nanoparticles‐based electrolyte. EDLC cells show specific capacitance of 76.4 and 44.51% of initial specific capacitance value at 2000th cycle for ZnO and TiO2‐based polymer electrolytes, respectively. © 2019 Wiley Periodicals, Inc.
