In-situ structural modification on spinel oxide to achieve efficient removal of refractory organics: Triple optimisation of degradation performance.

Spinel oxide has attracted interest in wastewater treatment, owing to its visible light (VIS) adsorption properties and bimetallic synergism. However, owing to the inefficient separation of photogenerated carriers and poor redox property, there is an urgent need to develop appropriate modification strategies to address these bottlenecks. This study aimed to develop CuFeO/CuFeSx (CFO/CFSx) heterojunction with oxygen vacancies (OVs) via an in-situ structural modification to trigger the generation of more radicals with low oxidant consumption for the efficient degradation of refractory organics.

Immobilization of Pb in waste water and soil by tourmaline-biochar composites (TBs): Characteristics and mechanisms.

Novel tourmaline-biochar composites (TBs) were synthesized by introducing tourmaline (TM) into pomelo peel biochar (BC). The surface properties of TBs and BC were studied and the adsorption performances for Pb were investigated. Compared to pristine BC, the adsorption ability for Pb on TBs was enhanced with the increase of TM in TBs, and up to 514.
