Constructing Ag-based photocatalysts by the incorporation of Ag(+) ions into metal/nonmetal oxides for removing organic pollutants is a recently developed strategy, but overcoming their own photocorrosion is still a tremendous challenge. In this work, an advanced Ag-based photocatalyst Ag2Ta4O11 is obtained by this strategy, which exhibits improved photocatalytic activity compared with Ta2O5 an...

Photocatalytic conversion of carbon dioxide (CO(2)) to hydrocarbons such as methanol makes possible simultaneous solar energy harvesting and CO(2) reduction, two birds with one stone for the energy and environmental issues. This work describes a high photocatalytic conversion of CO(2) to methanol using graphene oxides (GOs) as a promising photocatalyst. The modified Hummer's method has been app...

Physical adsorption and photocatalytic reduction of Cr(VI) in magnetic separable beads were investigated. In order to elucidate the kinetics of photocatalytic process, operating parameters such as catalyst dosage and the initial concentration were examined in detail. It was observed that the reduction rate of Cr(VI) increased with an increase in the catalyst loading, as this translated into an ...

The photocatalysis of phenol was studied using Fe3O4/ZnO core/shell magnetic nanoparticles (MNPs). The photocatalysts were synthesized by coating of ZnO onto the magnetite by precipitation method and characterized by XRD, SEM and FTIR measurements. Using the Taguchi method, this study analyzes the effect of parameters such as calcinations time, calcinations temperature and molar ratio of Fe3O4:...

In this study, magnetically separable ZnO/CuFe2O4 nanorod particles were synthesized by the green synthesis approach, using rambutan peel extract (Nephelium lappaceum L.) as a capping agent. The samples evaluated photocatalyst for degradation of Rhodamine B dye driven solar light irradiation. XRD patterns represented specific peaks ZnO and CuFe2O4 in composite. SEM TEM images showed rod-like sh...

The radical addition of thiols to alkenes is reported under photoredox conditions, using visible light and TiO2 as a cheap and readily available photocatalyst.

photocatalytic membranes exhibit great potential for water treatment since they combine the filtration and photo degradation in a single unit. although blending photocatalytic nanoparticles into polymeric thin film remains the simplest method to prepare the photocatalytic membrane, the entrapped photocatalyst showed less catalytic activity due to the agglomeration and shielding effects in the p...

A novel oxygen catalyst is prepared via the photodeposition of ruthenium(IV) oxide on a titania photocatalyst derived from a perruthenate precursor.

A reconstituted myoglobin with a synthetic cofactor having anionic binding sites effectively works as a photocatalyst for hydrogen generation in the presence of monomethylated bipyridinium.

BiVO₄/Mn1-xZnxFe₂O₄ was prepared by the impregnation roasting method. XRD (X-ray Diffractometer) tests showed that the prepared BiVO₄ is monoclinic crystal, and the introduction of Mn1-xZnxFe₂O₄ does not change the crystal structure of BiVO₄. The introduction of a soft-magnetic material, Mn1-xZnxFe₂O₄, was beneficial to the composite photocatalyst's separation from the liquid solution using an ...
