ZnO Nanoparticles for Photocatalytic Application in Alkali-Activated Materials

Sunlight activated ZnO mediated photocatalytic degradation of acetophenone in water

Solar photocatalysis is investigated as a potential advanced oxidation process for the removal of small amounts of acetophenone (ACP), a recalcitrant chemical pollutant detected in the effluent water from many petrochemical and other industries. Semiconductor oxide ZnO is used as the catalyst. The influence of various reaction parameters such as initial concentration of ACP, ZnO dosage, pH of t...

Rapid large-scale preparation of ZnO nanowires for photocatalytic application

ZnO nanowires are a promising nanomaterial for applications in the fields of photocatalysis, nano-optoelectronics, and reinforced composite materials. However, the challenge of producing large-scale ZnO nanowires has stunted the development and practical utilization of ZnO nanowires. In this study, a modified carbothermal reduction method for preparing large-scale ZnO nanowires in less than 5 m...

Hydrothermal Synthesis of ZnO/SnO2 Nanoparticles with High Photocatalytic Activity

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...
