Oxygen-vacancy enhanced CoO/CeO₂ heterojunction for synchronous regulation of sulfur resourcing and selenium adsorption separation from flue gas desulfurization wastewater

Abstract

Synchronously catalytic oxidation of sulfite (SO32-) and separation of selenium (Se) to achieve wastewater detoxication and sulfate purification from flue gas desulfurization wastewater is a desirable circular economy method but...
