A highly efficient and robust heterogeneous photocatalytic hydrogen evolution system was established for the first time by using the CoP/CdS hybrid catalyst in water under solar irradiation. The H2-production rate can reach up to 254,000 μmol h(-1) g(-1) during 4.5 h of sunlight irradiation, which is one of the highest values ever reported on CdS photocatalytic systems in the literature.

Differently modified TiO2 nanotubes were used to achieve a drastic change in the selectivity of a photocatalytic reaction. For the photocatalytic oxidation of toluene, depending on the electronic properties of TiO2 (anatase, rutile, Ru-doped), a strong change in the main reaction product (namely benzoic acid versus benzaldehyde) can be achieved, and certain undesired reaction pathways can be co...

UiO-66-X (X = H, NH2, NO2, Br) have been successfully synthesized and tested for their photocatalytic activity in water treatment. Results show that electronic effect of the ligand substituents greatly affects the photocatalytic activity of UiO-66. The rates obtained by different substituents are linearly correlated with their Hammett coefficients.

Novel disinfection methods are being sought to provide additional means of protection in a number of areas where disease outbreaks could lead to illness or fatalities. For example, the risk of contamination arising from contact with surfaces and medical devices has received much attention due to the rise in incidence of healthcare acquired infections. It is possible that reducing bio-burden on ...

Photocatalytic activity in the reduction of CO(2) with H(2)O to CH(4) was significantly enhanced by simply adding MgO to TiO(2) loaded with Pt. A positive correlation between CH(4) formation activity and basicity was observed. The interface between TiO(2), Pt and MgO in the trinary nanocomposite played a crucial role in CO(2) photocatalytic reduction.

For the first time, one-pot solution-phase selective-etching to create cuboctahedral Cu2O crystals enclosed by both stepped {111} surfaces and smooth {100} surfaces has been demonstrated. Investigation of photocatalytic performances indicates that the stepped cuboctahedral Cu2O crystals have higher photocatalytic activities than those of the common smooth ones.

Novel etched Cu2O cubes with exposed {110} facets are synthesized via an oxidative etching method at room temperature. The photocatalytic performance indicates that these architectures show higher photocatalytic activity than that of the normal Cu2O cubes in the degradation of methylene orange.

A g-C3N4/nanocarbon/ZnIn2S4 (CN/C/ZIS) nanocomposite with enhanced photocatalytic H2 production performance has been successfully synthesized. Based on the experimental results, for the first time, it has been demonstrated that nanocarbon could be integrated into a Z-scheme photocatalytic system and acted as an excellent solid electron mediator.

structural properties and chemical composition change the photocatalytic activity in tio2-sio2 nanopowder composite. the sio2-tio2 nanostructure is synthesized based on sol–gel method. the nanoparticles are characterized by x-ray fluorescents (xrf), x- ray diffraction (xrd), tunneling electron microscopy (tem), field emission scanning electron microscopy (fe-sem), uv-vis. spectrophotometer and ...

in the present work, zno/bi2o3, sno2/bi2o3/bi2o4 mixed oxide, bi2o3 rod-like and sno2 nanoparticle have been synthesized. the obtained samples were characterized by field emission scanning electron microscopy (fe-sem) and x-ray diffraction (xrd). the optical properties of samples were evaluated by uv-vis spectrophotometer. the photocatalytic activity of samples was evaluated by decolorization o...
