Biochar, a carbon-rich material made from the partial combustion of biomass wastes, is an
emerging material of interest as it can remediate pollutants and serve as a negative carbon …

Soil heavy metal contamination caused by mining activities is a global issue. These heavy
metals can be enriched in plants and animals through the food chain, and eventually …

Piezophotocatalytic technology has emerged as a promising wastewater treatment
approach recently. A novel piezoelectric material, the flexible bamboo-like BaTiO 3//ZnO …

In this work, a porous multi-functional biomass carbon was prepared by acid-base
modification method, which realized the reuse of waste cotton material. Then, the modified …

Acid recycling and arsenic recovery from strongly acidic wastewater are goals of the
metallurgical industry to reduce carbon emissions. In this study, arsenic was recovered …

Biochar can remove oppositely charged ionic species of Cd (II) and As (III)/As (V) from water
but the co-adsorption mechanisms of the metal (loid) s are poorly understood. This study …

Combined pollution caused by organic pollutants and heavy metals pose a significant
challenge to the adsorption process. In this study, iron-modified biochar (Fe-BC) was …

Hierarchical porous carbon (HPC) has attracted increasing research interest for energy and
environmental applications. HPC is conventionally fabricated by activated carbon, which …

Iron and manganese oxides are commonly found in nature, such as hematite and pyrolusite,
which strongly affect the migration and transformation of As (III). In this study, a series of …

Herein, Typha angustifolia was used as a charcoal source and chemically modified with a
strong oxidizing agent, potassium permanganate (KMnO 4), to obtain modified Typha …
