Influence of feedstocks and modification methods on biochar’s capacity to activate hydrogen peroxide for tetracycline removal
TLDR
H2O2 could either enhance or decrease the TC removal by biochar, depending on biochar type, H2O1 concentration and solution pH, but the removal efficiency was still quite low under optimum conditions.About:

Co-catalysis of trace dissolved Fe(iii) with biochar in hydrogen peroxide activation for enhanced oxidation of pollutants
TL;DR: In this paper , the activation efficiency of H2O2 can be enhanced through co-catalysis of trace dissolved iron (Fe) with biochar, which is a sustainable and low-cost approach for advanced oxidation of organic pollutants, but faces the challenge of a low yield of hydroxyl radical (˙OH).

Key Role of Persistent Free Radicals in Hydrogen Peroxide Activation by Biochar: Implications to Organic Contaminant Degradation
TL;DR: It was found that H2O2 can be effectively activated by biochar, which produces hydroxyl radical ((•)OH) to degrade 2-CB and the activation mechanism was elucidated by electron paramagnetic resonance (EPR) and salicylic acid (SA) trapping techniques.
