DFT Investigation of the Electronic and Catalytic Effects of Ni–Co–V Alloy Structures on the Theoretical Hydrolysis of NaBH₄

Öz

This study presents a density functional theory (DFT) investigation of Ni–V, Co–V, and Ni–Co–V alloy clusters (Ni₇V₂, Co₈V₂, Ni₆Co₄V₃, and Ni₄Co₄V₄) toward sodium borohydride (NaBH₄) hydrolysis for hydrogen generation. The catalytic behavior was analyzed by comparing bare clusters and their NaBH₄ + H₂O adsorbed reaction complexes. Structural optimizations reveal pronounced B–H bond elongation and metal–metal bond flexibility upon adsorption, particularly on Ni-rich surfaces. Electronic structure analyses indicate a systematic reduction in the HOMO–LUMO energy gap following NaBH₄ adsorption, confirming enhanced surface reactivity. Löwdin population analyses show significant charge transfer from borohydride to the metal framework, accompanied by a loss of hydride character and effective activation of hydrogen atoms. Thermodynamic calculations demonstrate that all reaction complexes are highly stable in aqueous media, with strongly negative enthalpy and Gibbs free energy values, indicating spontaneous and exergonic complex formation. Overall, Ni-rich and synergistic Ni–Co–V clusters exhibit superior electronic adaptability and structural stability, making them promising candidates for efficient NaBH₄ hydrolysis.
