Efficient Solar-Driven CO₂ Methanation and Hydrogen Storage Over Nickel Catalyst Derived from Metal-Organic Frameworks with Rich Oxygen Vacancies.

ABSTRACT: Solar-driven photothermal conversion of carbon dioxide (CO₂ ) to methane (CH₄ ) is a promising approach to remedy energy shortage and climate changes, where highly efficient photothermal catalysts for CO₂ methanation urgently need to be designed. Herein, nickel-based catalysts (Ni/ZrO₂ ) derived from metal-organic frameworks (MOFs) are fabricated and studied for photothermal CO₂ methanation. The optimized catalyst 50Ni/ZrO₂ achieves a stable CH₄ production rate of 583.3 mmol g^-1  h^-1 in a continuous stability test, which is almost tenfold higher than that of 50Ni/C-ZrO₂ synthesized via commercial ZrO₂ . Physicochemical properties indicate that 50Ni/ZrO₂ genera
