BiPO4/Bi2S3 photocatalysts were successfully synthesized by a simple two-step hydrothermal process, which involved the initial formation of BiPO4 rod and then the attachment of Bi2S3 through ion exchange. The as-synthesized products were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), a...

La/Fe/TiO₂ composite photocatalysts were synthesized by Sol-Gel method and well characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), nitrogen-physical adsorption, and UV-Vis diffuse reflectance spectra (UV-Vis DRS). It is interesting that the doped catalysts were in anatase phase while the pure TiO₂ was in rutile phase. In addition, the composites possessed bette...

A series of hydrotalcite (HT) and hydrotalcite modified by the transition metal ion Ni(II) was prepared with a modified coprecipitation method before being loaded with gold nanoparticles. The gold supported on Ni3Al hydrotalcite with a Ni2+/Al3+ molar ratio of 3:1 was investigated. Different techniques such as X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and UV-vis diffuse re...

The symmetric nano morphologies, asymmetric electronic structures, and as well the heterojunctions of developed photocatalytic systems perform a vital role in promoting light absorption, separation electron hole pairs charge carrier transport to surface when exposed near-infrared (NIR) light. In this present work, we synthesized hematite (α-Fe2O3) nanoparticles (NPs) by facile hydrothermal meth...

In the present work, UVA light-driven g-C3N4/TiO2 photocatalyst was synthesized for photodegradation of Carbamazepine (CBZ) in aqueous medium. The morphological, optical properties and structure TiO2, g-C3N4 prepared composites were analyzed using X-ray diffraction (XRD), Nitrogen adsorption–desorption isotherm based on BET, Raman Spectroscopy, Scanning Electron Microscopy (SEM) with EDX, UV–vi...

Extending the absorption range of TiO2 nanofibers to visible light is a great improvement photocatalytic property TiO2. In this study, TiO2/WO3/C/N were prepared by electrospinning using precursors soluble in water then annealing argon. Titanium(IV) bis(ammonium lactato)dihydroxide (TiBALDH) and ammonium metatungstate (AMT) used as precursor for WO3 respectively. Different volume ratios added s...

The present paper reports facile synthesis by simple chemical precipitation method for Zinc Oxide (ZnO) nanoparticles with cerium (Ce) and nickel (Ni) co-doped ZnO nanocrystals. different optimum conditions are analyzed in dual metallic (Ce/Ni) doped nanoparticles. Successful incorporation of is predicted X-ray diffraction (XRD) photoelectron spectroscopy (XPS). Additionally, optical effects we...

Long series of ozone profiles from 6 to 28 km at the Southern Tropics have been obtained from solar occultation measurements at twilight using a SAOZ spectrometer borne by long duration balloons. Two flights have been performed from Bauru in Brazil both in the summer, in February and March 2001 and 2003, from where the balloons 5 are moving westward at almost constant latitude (20 • ±5 • S). Th...

Penelitian ini bertujuan untuk mengetahui aktivitas fotokatalitik TiO2 yang disintesis dalam cairan ion 1-buti-3-metil imidzalium tetrafloroborat terhadap degradasi asam humat. Prekursor digunakan penelitian adalah TEOT (Tetra Etil Orto Titanat). Sintesis dilakukan dengan metode hidrotermal menggunakan sebagai pelarut perbandingan BMIM BF4 : air (3:7v/v). Berdasarkan hasil XRD diperoleh bahwa (...

The photocatalytic removal of water contaminants for ecological systems has become essential in the past few decades. Consequently, commercialization, cost-efficient, earth-abundant and easy to synthesize photocatalysts dye degradation are urgent need. We have demonstrated a simple feasible approach fabricating TiO2–SnO2 nanocomposite via urea-assisted-thermal-decomposition with different mass ...
