Pyrolysis of pharmaceutical sludge (PS) is a promising way of safe disposal and to recover
energy and resources from waste. The resulting PS biochar (PSBC) is often used as …

Nitrogen-doped biochar (HT NBC) was prepared from sewage sludge via hydrothermal
route-enabled carbonization, and the optimized HT NBC was found to efficiently activate …

Active sites on the surface of heterogeneous catalysts accounted for the generation of
reactive oxygen species (ROS) from peroxymonosulfate (PMS) toward organic degradation …

In this study, we first comprehensively studied peroxymonosulfate (PMS) and
peroxydisulfate (PDS) activation mechanisms using N, O codoped sludge biochar (NOSB) to …

The treatment and management of excess sludge is a huge challenge for environmental
protection and resource utilization. In this study, the sludge-based biochar containing iron …

As a recycling use of waste activated sludge (WAS), we used high-temperature pyrolysis of
WAS to support bimetallic Fe–Mn with nitrogen (N) co-doping (FeMn@ N–S), a customized …

This study shows that the simple pyrolysis of mixed sawdust, FeCl 3 and dicyandiamide can
produce Fe/N co-doped biochar (Fe-NC) with great catalytic and separation performances …

The efficient removal of sulfamethoxazole (SMX) from swine farming wastewater is a major
emerging environmental issue. This study successfully developed Fe-rich sludge biochar …

A novel approach of ball milling and oxalic acid was employed to modify sludge-based
biochar (BOSBC) to boost its activation performance for peroxymonosulfate (PMS) towards …

The pollution problem of livestock manure generated by the rapid development of farming
industry is becoming more and more serious, and its conversion into functional materials …
