Ba(PO) Photocatalyst for Efficient Photocatalytic Application.

Barium phosphate (Ba(PO)) is a class of material that has attracted significant attention thanks to its chemical stability and versatility. However, the use of Ba(PO) as a photocatalyst is scarcely reported, and its use as a photocatalyst has yet to be reported. Herein, Ba(PO) nanoflakes synthesis is optimized using sol-gel and hydrothermal methods.

Boosting the photocatalytic properties of NaTaO by coupling with AgBr.

AgBr/NaTaO composites, with different molar % of NaTaO (Br/NTO(X%)), have been synthesized by simple precipitation methods; bare NaTaO was synthesized by hydrothermal procedure, while AgBr was synthesized by a precipitation procedure using cetyl-tri-methyl-ammonium bromide (CTAB) and AgNO. Samples have been characterized by X-ray diffraction (XRD), N adsorption, UV-vis diffuse reflectance spectroscopy (DRS), Fourier-transform infrared spectroscopy (FT-IR), Transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). Photocatalytic activity of the as-prepared photo-catalysts was evaluated through photocatalytic degradation of rhodamine B (RhB), methyl orange (MO) and caffeic acid (CAFA) under UV and visible illumination.

Polyaniline coated tungsten trioxide as an effective adsorbent for the removal of orange G dye from aqueous media.

In this work, the core-shell PANI@WO composite was obtained from the reaction of aniline monomer polymerization with WO particles; sodium persulfate was used as an oxidant. Various analytical techniques such as scanning electron microscopy (SEM-EDS), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Brunauer-Emmett-Teller (BET), and X-ray photoelectron spectroscopy (XPS) were used to characterize the as-prepared PANI@WO adsorbent, which well confirmed that the WO particles were coated by polyaniline polymer. The PANI@WO composite was tested as an adsorbent to remove reactive orange G (OG) for the first time.

Z-scheme WO/PANI heterojunctions with enhanced photocatalytic activity under visible light: A depth experimental and DFT studies.

A WO@PANI heterojunction photocatalyst with a various mass ratio of polyaniline to WO was obtained via the in situ oxidative deposition polymerization of aniline monomer in the presence of WO powder. The characterization of WO@PANI composites was carried via X-ray diffraction (XRD), scanning electron microscopy (SEM-EDS), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), ultraviolet-visible diffuse reflection spectroscopy (DRS), X-ray photoelectron spectroscopy (XPS) and photoluminescence spectroscopy (PL). The photocatalytic efficiency of WO@PANI photocatalysts was assessed by following the decomposition of the Rhodamine B (RhB) dye under visible light irradiation (λ >420 nm).

Influence of Water on the Oxidation of NO on Pd/TiO Photocatalysts.

Two series of new photocatalysts were synthesized based on modification with Pd of the commercial P25 photocatalyst (EVONIK). Two techniques were employed to incorporate Pd nanoparticles on the P25 surface: photodeposition (series Pd-P) and impregnation (series Pd-I). Both series were characterized in depth using a variety of instrumental techniques: BET, DRS, XRD, XPS, TEM, FTIR and FESEM.
