Biochar has shown large potential in environmental remediation because of its low cost,
large specific surface area, porosity, and high conductivity. Biochar-assisted advanced …

Abstract Hexavalent chromium (Cr (VI)) contamination has gained interest from regulatory
authorities due to its high toxicity and carcinogenicity. Different approaches have been …

Olive stones have been widely used as a renewable energy biowaste source. As they are
rich in elemental carbon (40–45 wt%), much research focussed on effectively converting …

The pollution of heavy metals and organic compounds has received increased attention in
recent years. In the current study, a novel biochar-based iron oxide composite (FeYBC) was …

The difficulty of separating the powdered biochar from the environmental medium may lead
to secondary pollution and hinder the large-scale application of biochar as an adsorbent. An …

The limitation of low efficiency and complicated separation after adsorption make the
practical application of biochar a huge challenge. Here, one pomelo peel-derived magnetic …

Chromium originates from geogenic and extensive anthropogenic activities and significantly
impacts natural ecosystems and human health. Various methods have been applied to …

With the rapid growth of new-energy batteries and metallurgical industry, water pollution
caused by toxic heavy-metals from these sectors has increased to a new level, which is …

As we all know, environmental protection and sustainable energy utilization are significant
challenges for us. Due to their many excellent characteristics, carbon materials have been …

Peracetic acid (PAA)-based advanced oxidation processes (AOPs) were increasingly
identified as the alternative scheme in wastewater treatment. Cost-effective and easily …
