| Περίληψη: | This study reports the electrocatalytic characteristics of biochars prepared from Dioscorea bulbifera seed peel for hydrogen evolution reactions (HERs) through the electrochemical and tight binding quantum chemical study. The biochars obtained through pyrolysis at 300 °C and 400 °C, were subjected to chemical activation to obtained DBP@BC_300 and DBP@BC_400 respectively. The physicochemical properties of the activated biochars was evaluated using FTIR spectroscopic and BET surface area measurements. The electrocatalytic performance were evaluated using double layer capacitance values (C (Copyright © 2026 Elsevier Inc. All rights reserved.) |
