Peanut shell biotemplate to fabricate porous magnetic Co3O4 coral reef and its catalytic properties for p-nitrophenol reduction and oxidative dye degradation

The biotemplate assisted synthesis route is environmentally friendly, cost effective and easy. It employs a biomaterial like fruit waste, vegetable waste, bio-macromolecule, etc. for attaining a specific morphology of the as-synthesized product. Herein, we report the novel synthesis of magnetic, coral-reef like spinel-Co3O4 nanoparticles (m-Co3O4 NPs) by the immersion-calcination technique using peanut peel as a biotemplate. The as-synthesized...
