The enhanced TiO2-supported CdTe photocatalysts for photocatalytic hydrogen peroxide electrooxidation

Nahit AKTAŞ

At present, titanium dioxide (TiO2)-supported CdTe photocatalysts were prepared by wet impregnation method for photocatalytic hydrogen peroxide (H2O2) electrooxidation. The structural and morphology surface analyses of these photocatalysts were characterized by X-Ray diffraction (XRD), scanning electron microscopy-energy dispersive X-Ray (SEM-EDX) and mapping analysis, high-resolution transmission electron microscopy (HR-TEM), ultraviolet–visible (UV–VIS) spectroscopy, X-ray photoelectron spectroscopy (XPS), and inductively coupled plasma mass spectrometry (ICP-MS). In addition, the photocatal ...Более

A REMARKABLE SYNERGIC EFFECT OF POLY (ACRYCLIC ACID) HYDROGEL ANCHORED PD CATALYSTS IN FORMIC ACID ELECTROOXIDATION REACTION

Nahit AKTAŞ

Polymer-based catalysts have never been used before as anode catalysts in direct formic acid fuel cells. At present, Poly (acrylic acid), Poly (AA) was prepared and electrodes were constructed on graphite pencil (G) from these hydrogels. Furthermore, Pd doped Poly (AA)/G electrodes were prepared by employing electrodeposition techniques, and their formic acid electrooxidation (FAEO) activities were examined via cyclic voltammetry, chronoamperometry, and electrochemical impedance spectroscopy. These electrodes were characterized by DT-TGA, FTIR, and SEM-EDX. It was observed that Poly (AA)/G wer ...Более

Promoting formic acid and ethylene glycol electrooxidation activity on Ga modified Pd based catalysts

Hilal DEMİR KIVRAK | Nahit AKTAŞ

Herein, carbon nanotube (CNT)-supported Ga@PdAgCo catalysts were synthesized by sodium borohydride (SBH) sequential reduction method. These catalysts were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and inductively coupled plasma-mass spectrometry (ICP-MS). Characterization results revealed that these catalysts were succesfully preared at desired loading and atomic ratios. From the XRD pattern, the crystallite size of 0.5 Ga@PdAgCo(80:10:10)/CNT catalysts was found as 6.95 nm by utilizing the Scherrer equation. From ...Более

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 ...Более
