The construction of 3D hierarchical CdS/NiAl-LDH photocatalyst for efficient hydrogen evolution

Gaimei Gao et al.

Summary: A novel 3D hierarchical CdS/NiAl-LDH photocatalyst consisting of 1D CdS nanorods and 3D flower-like NiAl-LDH microspheres was successfully fabricated by an electrostatic assembly strategy. The CNA-20 hierarchical photocatalyst exhibited the optimum hydrogen evolution rate of 3.24 mmol g-1 h-1 under visible irradiation, which was 6.23 times higher than that of pure CdS. A type-II charge transfer mechanism was proposed based on energy band structures and first-principles calculation. The designed synergistic 1D/3D interface interaction effectively promoted the rapid separation and migration of photogenerated charges, thus facilitating H2 evolution.

Zhiliang Jin et al.

Summary: The construction of a reasonable interface structure can directionally regulate carrier transference for photocatalyst and improve photocatalytic performance. The formation of p-n heterojunction was accelerated by the opposite surface electronegativity of CoAl-LDH and Cu2O, providing a viable thermodynamic path for the transference of electrons. The strong internal electric field in p-n heterojunction greatly improved the charges separation and diversion, enhancing the number of electrons participating in reduction reactions.
