Factorial Design and Performance of a Hierarchical Floret-like Triplex LDH Composite in Facilitating the Oxygen and Hydrogen Evolution Reactions

. Despite the fact that NCF-LDH/GCN4/CDs demonstrate a commendable overpotential of 230 mV for the HER and 250 mV for the OER, their diminished activity emphasizes the superior catalytic synergy in GCN5-based systems, which may be attributed to enhanced electronic transfer and active site availability. Furthermore, the chronoamperometric studies for overall water splitting reflect the good stability and catalytic activity of NCF-LDH/GCN5/CDs, with no significant loss over 50 h. This result signifies an interface engineered between triplex-LDH and GCN5, enabling significant charge migration and tunable electronic properties. The factorial design and function of the floret-like 2-fold electrocatalyst offer an innovative strategy to meet the critical demands in producing green hydrogen during the water electrolysis process.
