a useful nanophotocatalyst (la,s-tio2) was prepared by a sol-gel method and characterized by uv–vis diffuse reflectance spectroscopy (drs), x-ray diffraction (xrd), photoluminescence emission spectroscopy (pl) and scanning electron microscopy (fesem). the results showed that the la,s-tio2, which calcined at 550 °c, contained only anatase phaseand its crystal size was 23 nm. in addition, the fes...

A well-designed scaffold that allows the full exposure of nanophotocatalyst to reactants is equally important with an efficient catalyst material in realizing a high-performance photocatalytic reaction. In this work, we develop three-dimensional (3D) bandgap tunable perovskite quantum dots (PQDs)/polyethersulfone (PES) monolithic film maximize specific area and enhance light harvesting, thereby...

Bleaching of Congo red catalyzed by ZrO2 nanoparticles was study under UV and sunlight irradiations. The nanoparticles of ZrO2 have been synthesized by controlled precipitation method. The concentration of ZrOCl2 and ammonia reactants and the calcinations temperature of ZrO2 were optimized for the control of nanoparticles size. Characterization of the prepared nanoparticles was studied by using...

The present research aimed to evaluate the photocatalytic activity of reduced graphene oxide and manganese ferrite nanocomposite supported on eucalyptus wood ash waste (WA) from industrial boilers, for decolorization methylene blue (MB) solutions, using sunlight as an irradiation source. For this, photocatalyst named MnFe2O4-G@WA was synthesized by a solvothermal method characterized analyzes s...
