Biomass-derived Activated Carbon with Nickel Ferrite Nanocomposite for Broadband Microwave Absorption

Abstract

This study presents a novel approach using a composite material consisting of Biomass-derived Activated Carbon and Nickel Ferrite Nanocomposite as an advanced option for achieving effective microwave absorption over a wide range of frequencies. The use of biomass, which is a sustainable and easily accessible resource, serves as the fundamental basis for this methodology. This approach effectively tackles the need for enhanced electromagnetic interference shielding in communication and radar systems by integrating activated carbon generated from biomass with nickel ferrite nanoparticles. Traditional approaches often encounter challenges related to the limited absorption of bandwidth and environmental considerations. The utilization of Biomass-derived Activated Carbon for Broadband Microwave Absorption (BMAC-BMA) presents a significant advancement, characterized by a noteworthy Absorption Coefficient of 14.25 Np/m, Return Loss of -20.37 dB, specific surface area of 580.25 m²/g, pore size distribution of 2.8 nm, Saturation Magnetization of 1.35 A/m and Reflection Coefficient of 0.1. These characteristic holds promise for driving breakthroughs in technology and communication systems. This study demonstrates the significant impact of using sustainable biomass resources in producing advanced materials for various applications.
