Synergy effect between tetracycline and Cr(VI) on combined pollution systems driving biochar-templated Fe3O4@SiO2/TiO2/g-C3N4 composites for enhanced removal of pollutants
Abstract Biochar-coupled Fe3O4@SiO2/TiO2/g-C3N4 composites were successfully constructed through simple sol–gel and calcination methods. The composites efficiently removed high-concentration toxic tetracycline (TC) by means of ·OH and ·O−2O2−, whose removal rate exhibited 91.88% during 3 h, and the degradation rate constant reached up to 0.0068 min−1. The excellent performance can be attributed to the high specific surface area, enhanced […]

Advances in preparation, application in contaminant removal, and environmental risks of biochar-based catalysts: a review
Abstract As a carbon-rich material produced by pyrolysis of biomass, biochar features low cost, large specific surface area, and widely available feedstocks based on the functional diversity and environmental-friendly properties, it has received increasing attention in the fields of pollutant removal due to three win–win effects of water remediation, carbon sequestration and reutilization of wastes.
