Photocatalytic degradation of pollutants in petroleum refinery wastewater by TiO2- and ZnO-based photocatalysts: Recent development

Abstract

Abstract Environmental pollution by Petroleum refinery wastewater (PRW) raises vital call for attention to scientist and industrialists due to its impact on human and eco-system. This manuscript reviews methods on modification of semiconductors, effect of operating parameters, reusability/stability, along with recent development on TiO2- and ZnO-based photocatalysts towards degradation of PRW pollutants. TiO2 and ZnO can be successfully modified to visible/solar light responsive photocatalysts. In-depth knowledge of reaction mechanism between photocatalysts and sorbates, structure formation in modified photocatalysts with respect to generation/mobilization of photo-charged carriers, informs the choice of composition of photocatalysts. Petroleum refineries are yet to benefit from heterogeneous photocatalysis due to some setbacks such as: recovery of photocatalysts for reuse, inability of the catalyst to degrade high concentration of pollutants, inability to handle the complex nature of PRW, and its reusability. Thus, a multifunctional and cost effective photocatalyst with reusability/stability needs more exploration to enable commercialization of the photocatalysts.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
