Published: July 8, 2024

This study sheds light on the synthesis, properties, and application of plant husk-derived biomass into biochar through thermochemical conversion processes. Gasification, pyrolysis, hydrothermal carbonization, torrefaction are processes that have been used in this regard. Investigation production variables revealed temperature, carbonization duration, heating rate significantly influence yield characteristics husk-based biochar, including surface area porosity, with temperature exerting most notable impact. It was observed gave rise to a relatively higher than other processes, which may be due low temperatures usually utilized. The properties typically exhibit carbon content exceeding 45% its total weight. has applied as catalyst, for soil amendment, environmental remediation, water treatment. identification research gaps shows need further exploration intricacies well consequences socio-environmental factors, technical scalability, economic feasibility.

Perfluorinated alkyl substances (PFAS), such as perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic (PFOA), are pervasive organic contaminants that widespread in aquatic environments, posing significant health risks to humans wildlife. Due their persistent nature, urgent removal is necessary. Conventional adsorbents inefficient at removing PFOS PFOA, highlighting the need for alternative materials. Herein, we present a synthetic method quaternary ammonium cation-doped carbon nanoparticles (QACNs) using solution plasma process efficient of PFOA. QACN formed simultaneously through one-step discharge nonequilibrium interface benzene pyridinium chloride. The resulting material exhibited high surface electrical charge enhanced hydrophilicity well an amorphous structure nonporous involving with undefined shape. obtained adsorbent demonstrated adsorption efficiency stability, adsorbing 998.45 889.37 mg g
