Interests: photochemical reaction engineering including photocatalysis, UV/hydrogen peroxide, Fenton/photo-Fenton, etc.; integration of advanced oxidation technologies and biological processes for wastewater treatment; effects of climate change on the quality and quantity of groundwater
Recent studies have been devoted to the use of advanced oxidation processes (AOPs) for the destruction of organic materials from wastewater, mainly because AOPs can entirely eradicate organics. Depending on the applications, different AOPs have been studied. Among AOPs, photocatalysis is a promising process of eradicating almost all types of organics in wastewater. Despite all advantages of TiO2, there are two major limitations in its photocatalytic activity, its activation in the ultraviolet range and a high rate of electron-hole recombination, leading to its low efficiency. Therefore, the photocatalytic efficiency depends on how well a photocatalyst can prevent electron-hole pair recombination. There have been many studies on photocatalysis including doping metals and non-metals as well as mixing different photocatalysts. This Special Issue will focus on the latest developments in photocatalysis including photochemical reaction engineering, photoreactor design, photocatalyst development, or combining photocatalysis with other processes to enhance organic degradation in water and wastewater.
This Special Issue strives to provide an overview on state-of-the-art photocatalytical technology in North America.

Abstract: Metal-organic frameworks (MOFs) have attracted substantial research attention owing to their tunable pore size, high pore volume, high specific surface area, and highly ordered crystalline porous networks. Previous studies have mostly focused on sensing, drug delivery, batteries, and selective catalysis; however, their application as photocatalysts has not been thoroughly reported. It is well known that bulk MoS2 is unsuitable for photocatalytic applications due to the insufficient reduction and oxidation ability for the photocatalysis. However, exfoliated MoS2 exhibits a direct band gap of 2.8 eV resulting from quantum confinement, which enables it to possess suitable band positions and good visible-light absorption ability. As a result, it is considered to be a promising candidate for photocatalytic applications. Encapsulating exfoliated MoS2 into MOF (MoS2@MOF) can lead to enhanced absorption in the visible light range compared with pure MOF and the highest hydrogen production rate could reach 68.4 μmol h-1g-1, which is much higher than that on pure MOF. With suitable band structure and improved light-harvesting ability, exfoliated MoS2@MOF can be a promising photocatalyst for hydrogen production.
