Seawater pollution is a significant global environmental problem. Various technologies and methods have been used to remove the contaminants found in saltwater. This experimental study investigates degradation of present seawater using solar photocatalysis, where combination TiO2 ZnO was used. The effects catalyst dosage, pH, reaction duration were assessed percentage removal efficiencies total...

There is growing recognition that cooperative effects exist under dual-mode (photo-thermal) heterogeneous catalytic excitation offer genuine prospects in the transition to a sustainable energy and chemicals economy. Solar beams can act as practical combined source of photons heat (via non-radiative relaxation after optical absorption) lead process intensification. This review provides critical ...

Generating charge carriers with lifetimes long enough to drive catalysis is a critical aspect for photoelectrochemical and photocatalytic systems, key determinant of their efficiency. Metal oxides are widely explored as photoanodes water oxidation. However, application limited by the disparity between picosecond–nanosecond electrons holes photoexcited in bulk metal versus millisecond–second tim...

Photo-thermal catalysis is among the most effective alternative pathways used to perform chemical reactions under solar irradiation. The synergistic contributions of heat and light during photo-thermal catalytic processes can effectively improve reaction efficiency alter design selectivity, even operational instability. present review focuses on recent advances in photo-thermal-driven reactions...

Due to their excellent properties, clays have been widely used in several applications, particularly in catalysis. In this paper, three clays were used as heterogeneous photo-Fenton catalysts for phenol and tyrosol oxidations. Particular attention was given to the effect of the main operating conditions on the process performance. A total conversion was obtained for both organic pollutants with...

ABSTRACT Surface-enhanced Raman spectroscopy (SERS) and tip-enhanced Raman spectroscopy (TERS) were until recently limited in their applicability to the majority of heterogeneous catalytic reactions. Recent developments begin to resolve the conflicting experimental requirements for SERS and TERS on the one hand, and heterogeneous catalysis on the other hand. This article discusses the developme...
