In recent years, semiconductor photocatalytic process has shown a great potential as a lowcost, environmental friendly and sustainable treatment technology to align with the“zero” waste scheme in the water/wastewater industry. The ability of this advanced oxidation technology has been widely demonstrated to remove persistent organic compounds and microorganisms in water. This paper presents the...

The efficiency of solar heterogeneous TiO2 photocatalysis and homogeneous photo-Fenton reaction for removal of Lambda Cyhalothrin, Chlorpyrifos and Diazinon from pesticide wastewater industry was investigated. The effluent quality was not complying for discharge into sewerage network. Therefore, adsorption of the remaining portions of pesticides using powdered activated carbon (PAC) was assesse...

This study investigates the performance of ultrafiltration (UF) by membranes coated with titanium dioxide (TiO2) photocatalyst under ultraviolet (UV) illumination in removing natural organic matter (NOM) and possibly in reducing membrane fouling. Experiments were carried out using heat-resistant ceramic disc UF membranes and humic acids as model substances representing naturally occurring organ...

Titanium dioxide (TiO2) is a well-studied photocatalyst that is known to break down organic molecules upon ultraviolet (UV) irradiation. Cellulose nanofibers (CNFs) act as an attractive matrix material for the suspension of photocatalytic particles due to their desirable mechanical and optical properties. In this work, TiO2-CNF composite films were fabricated and evaluated for photocatalytic ac...

We present an ab initio embedded cluster study of the ground and excited states for the rutile (1 1 0) surface with adsorbed water molecule. The calculated adsorption energies and geometries are compared with available experimental data. Upon photoexcitation, an electron–hole pair is created. We found that the electron is localized in the subsurface and thus cannot be directly involved in surfa...

The paper reports the preparation and photocatalytic activity of ZnO/SnO2 and SnO2 nanoparticles. These nanoparticles were synthesized by hydrothermal method. The products were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Their grain sizes are about 50-100 nm. The photocatalytic activities of these materials were investigated for congo red removal from aqueou...

Titanium dioxide (TiO2) is one of the most widely used photocatalysts due to its physical and chemical properties. In this study, hydrogen energy production using TiO2- titanate-based discussed along with pros cons. The mechanism photocatalysis has been elaborated pinpoint photocatalyst for better performance. chief characteristics limitations TiO2 have assessed. Further, TiO2-based modified a ...

With a distinct electronic structure and unsaturated coordination centers, supported single-atoms (SAs) have shown great potential in heterogeneous catalysis due to their superior activity, stability, selectivity. Over the last few years, fascination of SA-use spread also over photocatalysis, i.e., particular case which chemical reactions are activated by charge transfer from an illuminated sem...

There have been many articles on the degradation of pollutants by binary and ternary nanocomposites in field photocatalysis. However, there has no research comparing photocatalytic performance Rhodamine B (Rh B) between (M(M=Pt, Ag Au)-TiO2)@MoS2 nanocomposites. To this end, we prepared studied compared their efficiency with composites parent materials for B. We concluded that best polymer nano...
