Biochar-supported nanomaterials for environmental applications

Abstract

Immobilizing nanomaterials in highly porous, surface active, structurally stable biochar creates novel nanocomposites that combines the well-known advantages of both materials. The exceptional contaminant adsorption and/or catalytic degradation capabilities of these nanocomposites have attracted the attention of the scientific community for possible use in environmental applications. This paper reviews the different methodologies for synthesizing biochar-supported nanomaterials, the key physical and chemical characteristics of these nanomaterials, and their performance in environmental applications, as well as identifies current knowledge gaps and potential directions for further research and development.
