Removal of water-soluble lignin model pollutants with graphene oxide loaded ironic sulfide as an efficient adsorbent and heterogeneous Fenton catalyst

Recent developments in synthesis of attapulgite composite materials for refractory organic wastewater treatment: a review

“…Supported catalysts are particularly advantageous due to their high surface area and abundance of active sites, which enhance their catalytic efficiency compared to bulk catalysts. 47 Supported catalysts typically utilize porous materials as supports, including carbon, 48,49 graphene and its derivatives, 50,51 oxides such as ZnO, SiO 2 , Bi 2 O 3 , [52][53][54] and clays. 55,56 The active components, which can be metals or metal oxides, are deposited onto the surface of these supports to form the catalysts.…”

Synergistic effect of Fenton pretreatment and hydrothermal carbonization of lignin on the physicochemical properties of the resulting hydrochar

“…44 An et al explored the degradation of iron sulfides by the method of Fenton catalysis by mixing them with lignin model pollutants by making composites by solvothermal method. 45 Ying et al performed sequential Fenton oxidation with sulfomethylation pretreatment on lignin and showed that the synergistic effect of Fenton pretreatment and sulfomethylation pretreatment accelerated the depolymerization of lignin. 46 Although FP and HTC have gradually matured in the treatment of lignin, there are very few reports on their combined effects on the physicochemical properties of lignin.…”
