Abstract

The valorisation of agro-industrial residues as precursors for functional materials represents a sustainable and cost-effective approach for the development of advanced energy storage technologies. In this work, pistachio shells were used as a renewable biomass source to synthesise a hierarchical microporous carbon (denoted as PWC), which was activated using KOH as the porosity promoter. Textural characterisation revealed dual microporosity, with the coexistence of ultramicropores (
