“…Shi et al [61] compared the form and concentration of phosphorus in solid products of MHTC and HTC at different temperatures and at the same duration using the SMT protocol and P XANES spectrum. The study found no significant difference, except for a slightly better phosphorus promotion and preservation effect observed at a reaction temperature of 443 K. However, previous literature has demonstrated that MHTC offers more efficient energy input, significantly shortens the reaction time, and produces hydrochar with better pore distribution and activity [62]. This suggests that the precursor and reaction medium undergo more drastic changes under microwave conditions [61].…”

In recent years, the utilization of phosphorus-enriched biochar (PBC) has attracted significant attention due to its exceptional stability and surface reactivity. This review systematically summarizes the advancements in research related to the application of PBC as an adsorbent for remediating water contaminated with heavy metals. Initially, the precursors utilized in the production of PBC, encompassing biomass and phosphorus sources, are introduced. Subsequently, the distinct physicochemical properties and adsorption characteristics resulting from phosphorus doping on the biochar surface through various carbonization processes and parameters are elucidated. Additionally, the diverse adsorption mechanisms employed by PBC in removing heavy metals from water are analyzed. Lastly, future research prospects and associated challenges concerning PBC are presented. This paper aims to furnish comprehensive background information for the practical implementation of PBC in the purification of heavy metal-contaminated water environments.

“…Compared with conventional hydrothermal technologies, microwave-assisted hydrothermal processing of biomass can reduce the processing time as a result of the rapid volumetric heating, accelerate the processing rate due to the relatively low residence time, enhance the dewaterability, and lower the energy input. 93–99 Given these advantages of the microwave-assisted hydrothermal technology, a few studies focused on the utilization of microwave irradiation for the hydrothermal processing of biomass into valuable products. 96–98,100–102…”
