It is critical to design and synthesize superior metal-free PMS catalysts, particularly to
optimize the interaction between non-metallic heteroatoms and biochar, facilitating electron …

In this study, B-doped graphitic porous biochar (B-KBC) was prepared and used to activate
peroxydisulfate (PDS) for the removal of sulfamethoxazole (SMX). Experimental and …

A facile and scalable one-pot synthesis method was designed to fabricate N-doped biochar
from wood residue for peroxymonosulfate (PMS) activation. The urea: wood residue w/w …

N-doped biochars (NBCs) were prepared by pyrolyzing corncob biomass and urea in
different proportion which manifested superior catalytic performance of peroxydisulfate …

Biochars are low-cost and environmental-friendly materials, which are promising in
wastewater treatment. In this study, biochars were manufactured from C-phycocyanin …

Herein, hierarchical porous biochar from shrimp shell (PSS-bio) was prepared and applied
for persulfate activation for 2, 4-dichlorophenol removal. The pyrolysis temperature was …

The selection of biomass waste as a raw material for the preparation of metal-free catalysts
for the activation of peroxymonosulfate (PMS) for the degradation of organic pollutants is a …

Despite many studies on single doping (especially N, S) to improve the catalytic
performance of biochar in persulfate-based oxidation process (PS-AOP), the investigations …

Nitrogen (N) doping endows biochar with remarkable catalytic ability to activate
peroxysulfate for degradation of organics. Herein, a new strategy was proposed by creating …

For persulfate-based advanced oxidation process, the non-radical pathway is an important
route due to the selective oxidation of pollutants and its strong tolerance to complex water …
