Materials development for artificial photosynthesis, in particular, CO2 reduction, has been under extensive efforts, ranging from inorganic semiconductors to molecular complexes. In this report, we demonstrate a metal-organic framework (MOF)-coated nanoparticle photocatalyst with enhanced CO2 reduction activity and stability, which stems from having two different functional units for activity e...

This study synthesized nanocomposite photocatalyst materials from a mixture of Cu2O nanoparticles, ZnO and graphene oxide (GO) through coprecipitation hydrothermal methods. aims to determine the optimum composition Cu2O/ZnO/GO nanocomposites in degrading methylene blue. The was two steps: 1 synthesis nanoparticles method preparation GO modified Hummer method. 2 mixtures with form nanocomposites...

This study investigates the properties and potential application of Mg-PKS biochar composite for methylene blue solution (MB) adsorption. The was developed from palm kernel shell via steam activation followed by MgSO4 treatment carbonization. effect process parameters such as pH (4-10), contact time (30-90 min) adsorbent dosage (0.1-0.5 g) were investigated central design, response surface meth...

To enhance photocatalytic degradation of organic pollutants, coral-like TiO2 nanostructured thin films were chemically synthesized through the sol-gel method. The fabricated thin films were characterized by Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), nitrogen sorption isotherms, mercury porosimetry measurements, and UV-Vis Diffuse Reflectance Spectrum (DRS). The ...

Stibnite (Sb2S3) semiconducting material was successfully synthesized by a rapid and facile microwave route using antimony chloride (SbCl3) and sodiumthiosulfate (Na2S2O3) dissolved in propylene glycol (PG) containing different hydroxyethyl cellulose (HEC) masses. The phase identification, morphology, and elemental composition of products were characterized by X-ray diffraction (XRD), transmiss...

We have synthesized closely packed hexagonal 2D plates and clustered nanoparticle morphologies of Ba(Sb/Ta)2O6 (BSTO) perovskite via the polymerizable complex method for photocatalytic dye degradation activities. The BSTO crystallized in a structure. presence Ba2+, Sb5+, Ta5+, O2− chemical states identified from XPS confirmed formation mixed phase accompanied with minor amount TaOx. Furthermore...

This study investigated the photo-degradation of methyl orange (MO) as a type of azo dye using a CuO/α-Fe2O3 nanocomposite. A CuO/α-Fe2O3 powder with a crystalline size in the range of 27-49 nm was successfully prepared using simple co-precipitation along with a sonication method. The characterization of the synthesized sample was done via XRD, FE-SEM, EDS, FTIR and DRS analyses. The Tauc equat...

The aim of this study is to obtain optimal decolourization conditions for Acid blue-7 (AB7) wastewater treatment by Ti/TiO2 photoelectrocatalysis using response surface methodology (RSM). On the basis of a three-variable Box-Behnken design (BBD), RSM was used to determine the effect of pH values (ranged from 3.2 to 6), light intensity (ranged from 10 to 20 ×10 2 μW/cm 2 ) and bias potential (ra...

Two-dimensional (2D) metal-organic frameworks (MOFs) are fascinating photocatalytic materials because of their unique physical and catalytic properties. Herein, we report a new (E)-4-(3-carboxyacrylamido) benzoic acid [ABA–MA] ligand synthesized under facile conditions. This ABA–MA is further utilized to synthesize copper-based 2D MOF via the solvothermal process. The resulting characterized fo...
