Tailoring Cadmium Composition on Titanium Dioxide to Achieve Enhanced Photocatalytic Glucose Fuel Cell Anode Performance

Nahit AKTAŞ

In this study, titanium dioxide (TiO2)-supported Cd catalysts were prepared at 0.05-3 of Cd loading by employing the incipient wetness impregnation method. These catalysts were characterized via X-ray diffraction (XRD), scanning electron microscopy-energy-dispersive X-ray (SEM-EDX), high-angle annular dark-field scanning transmission electron microscopy and TEM-EDS mapping, inductively coupled plasma-mass spectrometry ( ICP-MS), X-ray photoelectron spectroscopy (XPS), temperature-programmed reduction (TPR), temperature-programmed oxidation (TPO), and temperature-programmed desorption (TPD). XR ...Daha fazlası

The role and effect of CdS-based TiO2 photocatalysts enhanced with a wetness impregnation method for efficient photocatalytic glucose electrooxidation

Nahit AKTAŞ

The 0.1 CdS-based TiO2 photocatalysts with different atomic ratios were synthesized by the wetness impregnation (WI) method. These photocatalysts were characterized to actively determine surface area using TPx analyses (TPR, TPO, and TPD). Furthermore, surface structures and properties of photocatalysts were defined by analyses such as XRD, UV-VIS spectroscopy, SEM-EDX and mapping, fluorescence spectroscopy, TEM-EDS, and XPS. The photocatalytic activities of photocatalysts were examined by CV, CA, and EIS electrochemical analyses to investigate use in photocatalytic fuel cells (PFCs) in glucos ...Daha fazlası

Photocatalytic glucose electrooxidation of titanium dioxide doped CdTe enhanced for a photocatalytic fuel cell

Nahit AKTAŞ

The 0.1 CdTe/TiO2 photocatalysts with different atomic molar ratios (90-10, 70-30, 50-50, and 30-70) were synthesized by the wetness impregnation method and characterized by the XRD, SEM-EDX and mapping, N2 adsorption-desorption, ICP-MS, TEM-EDS and STEM mapping, UV-VIS spectroscopy, fluorescence spectroscopy, XPS, TPR, TPO, and TPD analyses. The photocatalytic activities were examined to investigate by CV, CA, and EIS electrochemical analyses for photocatalytic fuel cells (PFCs) in glucose solution in the dark and under UV illu-mination. The characterization analyses revealed that anatase TiO ...Daha fazlası

The effect of titanium dioxide-supported CdSe photocatalysts enhanced for photocatalytic glucose electrooxidation under UV illumination

Nahit AKTAŞ

The wetness impregnation method was used to synthesize 0.1 CdSe/TiO2 photocatalysts with different atomic molar ratios (90-10, 70-30, 50-50, and 30-70). These catalysts were characterized by XRD, SEM-EDX and mapping, TEM-EDS, UV-VIS spectroscopy, fluorescence spectroscopy, XPS, TPR, TPO, and TPD analyses. Cyclic voltammetry (CV), chronoamperometry (CA), and electrochemical impedance spectroscopy (EIS) analyses were performed to examine the photocatalytic activity for photocatalytic fuel cells (PFCs) in glucose solution in the dark and under UV illumination. The characterization analyses reveal ...Daha fazlası

Quantum size effect of cadmium-doped titanium dioxide photocatalysts towards methylene blue degradation and electrooxidation

Nahit AKTAŞ

At present, titanium dioxide supported cadmium catalysts were prepared at 0.5-5?admium loading by impregnation method. 0.5?d/TiO2 catalyst was characterized with scanning electron microscopy-energy dispersive X-ray (SEM-EDX), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). Characterization results revealed that by cadmium doping to titanium dioxide, surface electronic properties and crystal structure of Cd/TiO2 catalysts changed as obtained from SEM-EDX, XRD, and XPS. Following this, methylene blue degradation and electrochemical oxidation measurements were examined under ...Daha fazlası
