Sonochemical synthesis was used to create novel solar light active Mg-doped CuO nanoparticles. Through a chemical impregnation method, the produced nanomaterial changed with PVA (polyvinylalcohol). The optical properties, crystal structure, and surface morphologies of synthesized nanomaterials were probed by UV-visible spectroscopy (UV-vis-DRS), Fourier transform infrared (FT-IR), Raman spectro...

1 Preface All products are continuously being improved for better performance. Spectrometers have developed in many ways since the introduction of simple and moderately priced Spectrophotometers which were commercially available from the mid 1950’s. 1 Such improvements have enabled SCINCO to manufacture PDA type UV-Vis. Spectrophotometers. The scope and performance of conventional single channe...

This work unravels a sudden deactivation of Pt/TiO2 (P25) during the initial stages of photocatalytic H2 evolution from aqueous solution that, until now, has gone unnoticed, using a unique combination of in situ photodeposition of Pt with an on-line gas detector system. Utilizing a set of techniques, including highresolution transmission electron microscopy (HRTEM), X-ray photoelectron spectros...

The visible-light response is a necessary condition for titanium dioxide (TiO2) photocatalyst to function as visible light active photocatalyst. This can be solved by investigation of the bandgaps and optimization doping levels multivalency metal-doped TiO2. In this study, pure Cu, Fe, Ni-doped TiO2 photocatalysts were prepared sol‐gel method. characterized using XRD, FTIR, FESEM, EDX, N2 physi...

Blue nano pigments of CoAl2O4 were successfully prepared by polyol method. Two different groups of materials containing chloride and acetate compounds were used to synthesis the nano pigments. The nano pigments were calcinated at 1100 °C. The CoAl2O4 nano pigments were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), diffuse reflectance spectroscopy (DRS), dynamic li...

A highly-efficient graphitic carbon nitride (g-C3N4) photocatalyst for visible light photodegradation of rhodamine B (RhB) and methyl orange (MO) simulating dyeing wastewater was synthesized by the thermal polycondensation melamine. The photocatalysts were characterized TG-DTG-DSC, XRD, EA, XPS, FT-IR, SEM, TEM, BET, PL UV-vis DRS. results showed that photocatalytic performance g-C3N4 at a high...
