Abstract Developing bifunctional electrocatalysts from earth‐abundant first‐row transition metals for large‐scale hydrogen production through water electrolysis is both promising and challenging. This study presents a ternary layered double hydroxide (LDH) as electrocatalyst the evolution reaction (HER) benzyl alcohol oxidation (BAOR). The synergy between 2D NiFeCo LDH non‐Ti‐based Nb 2 CT x MXene enhances electrochemical performance. achieves excellent results with low potential of 1.5 V versus RHE at 100 mA cm⁻ BAOR, an overpotential 320 mV 50 HER, stability over h. A solar cell‐powered HER||BAOR system shows faradaic efficiency ≈73.92% benzaldehyde solar‐to‐hydrogen (STH) ≈39.67%. In situ Raman analysis identifies oxyhydroxide group real catalytic active site during BAOR. These findings offer valuable insights linking fundamental research technological innovation to address global challenges.

Water electrolysis represents one of the most environmentally friendly methods for hydrogen production, while its overall efficiency is primarily governed by electrocatalyst. Nickel sulfides, e.g., Ni3S2, are considered to be highly promising catalysts evolution reaction (HER) due their distinctive chemical structure. However, practical application Ni3S2-based electrocatalysts hindered unsatisfactory high overpotential in HER and weakened catalytic performance under alkaline conditions. Therefore, this regard, further research on being carried out tackle these challenges. This review provides a comprehensive survey latest advancements improving electrocatalysts. The may offer some inspiration rational design synthesis novel transition metal-based with enhanced water performance.
