Room-Temperature Alane Dehydrogenation for Visible-Light-Driven Photocatalytic Hydrogen Supply System.

ABSTRACT: Solar-driven hydrogen supply systems filled with high-density hydrides can overcome the traditional limitations of external heating and power sources. However, these systems commonly rely on photothermal effects to elevate the hydride surface temperature, significantly restricting their photon-to-chemical conversion efficiency. Therefore, exploring hydrogen supply systems driven by visible-light photocatalysis offers immense potential for achieving enhanced photon-to-chemical conversion. In this study, a non-thermodynamic regulation mechanism based on the dehydrogenation of alane and driven by the broadband-responsive photocatalysis of AlH₃-MOF is investigated. The dehydrogenation rate under visible-light irradiation reaches 30.8 µmol g^-1 min^-1, achieving a
