The development of heterogeneous catalysts is one of the pillars of modern material
science. Among all supports, carbonaceous ones are the most popular due to their high …

Microplastics (MPs) pose an emerging threat to soil ecological function, yet effective
solutions remain limited. This study introduces a novel approach using magnetic biochar …

Traditional wastewater treatment plants are not suitable for removing potentially hazardous
compounds released daily into effluents, resulting in their accumulation in the environment …

Transition metal iron and persistent free radicals (PFRs) both affect the redox properties of
biochar, but the electron transfer relationship between them and the coupling reduction …

In this study, a set of comprehensive experiments were conducted to explore the effects of
temperature on the biodegradation, bioavailability, and generation of reactive oxygen …

Cr (VI) released into the environment inevitably co-exists with other contaminants, such as
heavy metal ions, thus altering the performance of bacteria for Cr (VI) reduction; however …

In order to fully exploit the potential of magnetic biochar-based persulfate (PS) systems, Mn
was utilized to modify the magnetic biochar-based catalysts through impregnation-pyrolysis …

In addition to the adsorption and immobilization capacities of iron-modified biochars, these
materials produce persistent free radicals (PFRs) that can carry out metal [ie, Cr (VI)] redox …

For an exhaustive removal of Cr (VI), three different types of biochar were prepared,
modified and evaluated for Cr (VI) removal from wastewater. Magnetic eucalyptus biochar …

Much chromite ore processing residue (COPR), which is defined as hazardous solid waste
due to virulent Cr (Ⅵ), is produced from chromium salt industry. C-bearing dust from steel …
