Preparation and characterization of a biochar from pistachio hull biomass and its catalytic potential for ozonation of water recalcitrant contaminants

▸ This work demonstrates the preparation of a biochar from pistachio hull biomass. ▸ The prepared catalyst was very active in catalyzing the dye ozonation process. ▸ The COP mineralized RR198 to a much greater extent than does single ozonation.
