Activation of peroxymonosulfate by biochar-based catalysts and applications in the degradation of organic contaminants: A review
Abstract
Abstract Sulfate radical-based advanced oxidation processes (SR-AOPs) have received intensively attention due to the ability and adaptability. Biochar-based catalysts have been regarded as the effective catalysts for activating peroxymonosulfate (PMS) to generate sulfate radicals (SO4•-). This article discussed the advance of the PMS activation by biochar-based catalysts. Firstly, the sources and synthesis methods of biochar-based catalysts have been discussed. Secondly, the different activation mechanisms (including radical pathways and non-radical pathways) of pristine biochar, heteroatom doping biochar and biochar composites catalysts for PMS activation are reviewed, respectively, which includes (i) the significant role of persistent radical (PFRs) and the special structures (defects and graphitization) of pristine biochar, (ii) the effects of element doping (especially N atom) and metal species on the biochar catalysts, (iii) the production mechanisms of reactive oxygen species (ROS) and special non-radical mechanism. Thirdly, the influences of PMS and catalysts concentration, temperature, pH, anions and natural organic matter (NOM) on the contaminants degradation process have been presented. Finally, the conclusion and prospects section discussed the challenges and possible future directions for the degradation of contaminants by biochar/PMS systems. This review is expected to provide new ideas for the application of biochar-based catalysts and broaden the ways for the removal of organic contaminants.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
