Abstract: The hydrogen storage/release system based on sodium borohydride (NaBH 4) is the most practical chemical hydrogen storage and release method. But it requires efficient, reusable and inexpensive catalysts to drive the reaction under ambient condition. Coupling photocatalysis with traditional thermal catalysis is an ideal strategy to enhance the reaction efficiency. Inspired by the photosensitive nature of polydopamine (PDA), PDA-coated CoFeAl layered double hydroxides (CoFeAl-LDH@PDA) have been designed by in-situ polymerization for photothermal co-catalysis of H 2 production from NaBH 4 under visible light. The close contact between PDA and CoFeAl-LDH creates a heterogeneous structure, which accelerates the photogenerated charge transfer and the efficiency of electron-hole partitioning, resulting in the photocatalytic activity greatly enhanced. Moreover, the addition of PDA enhanced the absorption of visible light by the catalyst, which made the system have higher heat in the photothermal conversion, and promoted the photothermal synergistic catalytic hydrogen production. In addition, the cycling stability of CoFeAl-LDH@PDA was significantly improved by the protective layer of PDA, and 89 % of the initial yield could be maintained after 5 cycles. The structure design provides a new idea to further promote the practical application of NaBH 4 photothermal catalysis for hydrogen production. [Display omitted] • Self-polymerizing PDA layer was In-situ encapsulated onto CoFeAl-LDH. • PDA layer presents multifunction: Rapid photothermal conversion, building heterojunction, corrosion protection. • The mechanism of photothermal co-catalyzed sodium borohydride hydrogen production is discussed in detail.
