Abstract

This study presents a sustainable approach to generating green hydrogen (GH2) by repurposing eggshell membrane (ESM), a common biowaste, as a novel catalyst support in water electrolysis. Utilizing ESM, typically discarded from widely consumed eggs, we developed a method to upcycle this biowaste into valuable electrocatalysts. Through chemical and thermal treatments followed by electrochemical processes, we enhanced ESM with transition metal-based active sites and highly reactive Fe sites, significantly improving electrocatalytic efficiency for GH2 production. The ESM's unique nanofibrous and porous structure, alongside intrinsic chemical elements like P, O, N, and S, facilitated metal ion adsorption and nanoparticle formation, as revealed by X-ray photoelectron spectroscopy. These modifications led to exceptional activity and durability in oxygen and hydrogen evolution reactions. This approach not only leverages biowaste for environmental sustainability but also advances the development of efficient electrocatalysts, highlighting the potential of biomaterials in renewable energy technologies.

Keywords: Bio-waste recycling, eggshell membrane, water electrolysis, green hydrogen, metal-based electrocatalysts
