A critical review on biochar-based catalysts for the abatement of toxic pollutants from water via advanced oxidation processes (AOPs)

Recent progress in TiO2–biochar-based photocatalysts for water contaminants treatment: strategies to improve photocatalytic performance

“…Biomass contains nearly all of the living things on the planet and the biological material produced, processed, and expelled by them. 116 Its broad existence and plentiful stocks ensure the creation of TiO 2 –biochar composites. Therefore, biochar has a conspicuous advantage in feedstock costs compared to other carbon materials and serves an essential function green energy.…”

Synthesis of an Environmentally Friendly Modified Mulberry Branch-Derived Biochar Composite: High Degradation Efficiency of BPA and Mitigation of Toxicity in Silkworm Larvae

“…It has attracted considerable attention in the remediation of hazardous pollutants in wastewater due to its extremely low cost and environmental friendliness. The conversion of various biomasses to BC has been reported in much of the literature [ 3 , 4 , 5 , 6 ], including activated sludge, animal manure, agricultural wastes, or carbonaceous sources such as bamboo, sawdust, and coconut shells. Currently, a large amount of agricultural waste is discarded every year, which poses a great challenge to the safe disposal and utilization of carbon-rich biomass residues.…”

Synthesis of Pr3+-doped WO3 particles: correlation between photoluminescent and photocatalytic properties

“…The generation of these electron pairs promotes the formation of reactive oxygen species (ROS) such as cOH − and O 2 − , which promote the degradation of organic contaminants. 14,15 However, semiconductors have some limitations such as recombination of photoelectron pairs and e − /h + and a wide bandgap. These difficulties can be overcome by performing some modications such as nanoparticles, doping, heterojunctions.…”
