TL;DR: In this paper, the photo-degradation mechanisms of persistent organic pollutants (POPs) and the recent progress in ZnO nanostructured fabrication methods including doping, heterojunction and modification techniques as well as improvements of ZnOs as a photocatalyst are reviewed.

TL;DR: In this article, a simple sol-gel method at low temperature was used to prepare zinc oxide (ZnO) nanoparticles, which were characterized with different techniques such as X-ray-diffraction (XRD), Brunauer-Emmett-Teller (BET), ultraviolet-visible (UV-vis) spectrometry and field emission scanning electron microscopy (FESEM).

TL;DR: In this article, a low temperature sol-gel method was used to synthesize ZnO/rGO nanocomposites (NCs) for degradation of perfluorooctanoic acid and methyl orange in aqueous solution under solar irradiation.

TL;DR: The objective of this study is to evaluate the feasibility of setting up an integrated recirculating aquaculture system using the membrane technology, which possibly utilizes microfiltration, ultraFiltration, nanofiltration or reverse osmosis modules, to improve the quality of aquacultural water while minimize the wastewater discharge and increase the water reuse.

TL;DR: In this work, synergistic effect of solar photocatalysis integrated with adsorption process towards the degradation of Congo red (CR) was investigated via two different approaches using a photocatalytic membrane reactor and it was observed that Fe-doped ZnO could enhance the photoactivity of ZNO under solar light.
