Non‐noble metal photocatalysts have received widespread attention with the popularity of photocatalytic hydrogen evolution. Here, a brand‐new series of ZnFe 2 O 4 /Al‐MCM‐41 photocatalysts were synthesized with a simple hydrothermal strategy and analyzed through various characterizations. The results revealed that 40 % loading of Zinc ferrite (ZnFe 2 O 4 ) showed the most remarkable hydrogen evolution effect without noble metal decorated. It has a maximum photocatalytic hydrogen evolution of 4525.4 μmol g −1 in 3 h, which is about 5.4 times higher than that of pure ZnFe 2 O 4 . These results are mainly owing to the loading of Al‐MCM‐41, which can provide more surface reaction sites and delay the recombination of charges and holes. Moreover, the composite shows good cyclability and stability, with a high hydrogen evolution after three repeated cycles.
