Abstract
and an overpotential reduction of 120 mV against bare CNTs. Fe-Cu electronic interactions and CNT-mediated mass transport resulted in a 4.3-fold increase in exchange current density that the catalyst achieved relative to its monometallic counterparts. This work presents a transforming solution for scalable green hydrogen generation using a creative dual-engineering approach, molecular-scale metal anchoring, and a nano-architecture conductive support, thus solving major obstacles in catalyst durability and activity.
