Over the past decade, biochar-supported nZVI composites (nZVI/biochar) have been
developed and applied to treat various pollutants due to their excellent physical and …

This literature review explores the assessment of biochar quality and its impact on soil
properties using diffuse reflectance spectroscopy. Biochar, a product of biomass pyrolysis, is …

Electroactive Fe-biochar has attracted significant attention for As (III)/Cr (VI) immobilization
through redox reactions, and its performance essentially lies in the regulation of various …

The interpretation of C1s XPS spectra from disordered oxygenated carbons remains
uncertain despite a variety of schemes reported in the literature. Here, a thermoseries of …

The complex heterogeneous nature of chars has confounded the complete analysis of the
Raman spectra of these materials. The additional shoulders observed on the defect (D) …

Despite the exotic electromagnetic properties have been demonstrated in metamaterials to
date, how to effectively adjust negative electromagnetic parameters remains a challenge …

Redox processes mediated by biochar (BC) enhanced the transformation of Cr (VI), which is
largely dependent on the presence of PFRs as electron donors. Natural or artificial dopants …

Sewage sludge biochars were obtained at different pyrolysis temperatures from 300° C to
900° C and their macro-and microscale properties were analyzed. The biochar's plant …

This work reports an innovative route for biomass upgrading via hydrodeoxygenation (HDO)
reactions which avoids external high-pressure hydrogen supply and harsh conditions (such …

In recent years, sulfite (S (Ⅳ)), as an alternative to persulfates, has played a crucial role in
eliminating antibiotics in wastewater, so there is an urgent need to develop a cheap …
