In this study, N, Scodoped titania photocatalyst was synthesized through an efficient and straight forward method using a single source, ammonium sulfate, as modification agent of titanium isopropoxide (TTIP) precursor. The catalyst was characterized by X-ray powder diffractometer (XRD), element Analysis of carbon, hydrogen, nitrogen (CHN), scanning electron microscopy (SEM), diffuse reflectanc...

in this study, the photocatalytic degradation of methyl orange and congo red dye was investigated inaqueous solution using c,n,s-tridoped sno2 nanoparticles as a nano photocatalyst. the degradationwas carried out under different conditions including the photocatalyst amount, initial concentrationand ph of the solution. the results indicated that the degradation of methyl orange and congo redwas...

s-doped and bare mesoporous tio2 were prepared using titanium tetraisopropoxide and thiocarbamide as raw materials. prepared materials were characterized by means of fourier transform infrared spectroscopy ft-ir, thermogravimetry-differential scanning calorimetry (tg-dsc), x-ray diffraction (xrd), uv–vis absorption spectroscopy, brunauer–emmett–teller (bet) specific surface area and barrett–joy...

Sulfur doped titanium dioxide anatase nano-photocatalyst with different copper loadings (5, 10, 15, and 20 w/w %) was synthesized by hydrothermal method. The fabricated nanocatalysts were found to have high surface area, high aspect ratio, good surface morphology and high metals dispersion. The synthesized nanocatalysts were characterized by X-ray powder diffraction (XRD), Scanning electron mic...

Overall water splitting was achieved on a simple perovskite oxynitride photocatalyst, CaTaO2N, with an absorption edge at 510 nm. This photocatalyst, modified with a Rh-Cr bimetallic oxide cocatalyst, produced stoichiometric H2 and O2 steadily under UV and visible light irradiation after coating of the photocatalyst particles with amorphous Ti oxyhydroxide.

This study examined the antimicrobial/antifungal ability of a tissue conditioner containing a photocatalyst for Escherichia coli, Streptococcus mutans, Staphylococcus aureus and Candida albicans. The photocatalyst was mixed with tissue conditioners powders at concentrations of 0, 10, 15, and 20 wt%. Tissue conditioners powders containing a photocatalyst were mixed with liquid to make test speci...

A Co3O4/Fe2O3 composite nanofiber-based solar photocatalyst has been prepared, and its catalytic performance was evaluated by degrading acridine orange (AO) and brilliant cresyl blue (BCB) beneath solar light. The morphological and physiochemical structure of the synthesized solar photocatalyst was characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), X-...
