TiO2 is a promising photocatalyst with limited use in practical applications owing to its wide bandgap, narrow light response range, and rapid recombination of photoexcited carriers. To address these limitations, novel 1D/2D TiO2/ZnIn2S4 heterostructure was designed according the principles S-scheme heterojunction. The (TZISx) hybrids prepared via hydrothermal method afforded significant improv...

It has been shown that the photocatalytic activity of doped semiconductor with some nonmetals is higher than a pure semiconductor. Hence, with an attempt to achieve higher photocatalytic activity, doped ZnO with C, N, and S was prepared by a sedimentary process and used for the photocatalytic degradation of Fluocinolone Acetonidin as a drug in aqueous solutions.  ...

A novel Ag-based photocatalyst Ag2Nb4O11 has been obtained, which exhibits universal high-efficiency photodegradation activity for rhodamine B (RhB), methylene blue (MB) and methyl orange (MO) organic dyes. The cycling ability (40 times) and recovery characteristics indicate that the Ag2Nb4O11 photocatalyst has high stability, durability and regeneration ability.

A flower-like S-scheme BP/BiOCl photocatalyst has been successfully prepared via a simple co-precipitation method, which shows high photocatalytic activity and good stability.

a floating polymer-supported photocatalyst based on polystyrene impregnated with titaniumdioxide particles was developed using a facile solvent-cast method at ambient temperature. the preparedphotocatalysts were characterized by x-ray diffraction, scanning electron microscopy and fourier transforminfrared spectroscopy. the photocatalytic activity of the developed photocatalysts was investigated...

H photocatalysis is of broad interest in materials chemistry and materials science, particularly with the rapid growth of research attention being directed toward energy-related applications, pollution mitigation, and other related areas of environmental impact. A literature survey reveals more than 9000 papers with the word photocatalyst or photocatalysis in the title published during the last...

The highlight summarizes Cheng et al .’s work on fabricating CdS/polymer S-scheme photocatalyst for efficient H 2 production. intimate CdS-polymer binding forms a sturdy heterojunction and the photocatalytic mechanisms are profoundly investigated by in-situ characterization.

Metal sulfides-based nanomaterials have been used as a class of efficient solar driven photocatalysts. However, the H₂-production rate observed over these photocatalysts remains problematic. Here, the AgInS₂-xAg₂S-yZnS-zIn₆S₇ (x, y, z = 0 or 1) nanocomposites with controlled compositions have been successfully prepared by a simple hydrothermal method with AgI polyhedrons as silver source. The o...

A novel photocatalyst based on TiO2-PANI composite supported on small pieces of cork has been reported. It was prepared by simple impregnation method of the polyaniline (PANI)-modified TiO2 on cork. The TiO2-PANI/Cork catalyst shows the unique feature of floating on the water surface. The as-synthesized catalyst was characterized by X-ray diffraction (XRD), scanning electron micrograph (SEM), t...

Spectral sensitization of a mesoporous graphite carbon nitride (mpg-C(3)N(4)) photocatalyst was investigated by depositing magnesium phthalocyanine (MgPc) to expand the absorption to wavelengths longer than those of the principal mpg-C(3)N(4). The obtained sample, MgPc/Pt/mpg-C(3)N(4) (Pt as a cocatalyst) showed stable photocatalytic evolution of hydrogen from aqueous solution in the presence o...
