Solar‐Driven Hydrogen Production from Methanol Decomposition Catalyzed by High‐Entropy Spinel Oxides

. The performance is significantly higher than that under thermocatalytic conditions at the same temperature and surpasses the activity of the state-of-the-art catalysts. The catalyst exhibits long-term stability over 80 h through in situ removing deposited carbon, and thus HEOs show great promise for efficient hydrogen production from methanol decomposition under mild conditions.
