Nickel aluminum oxide hydrate supports ZIF-67 with different morphologies to achieve the improvement of photocatalytic hydrogen production performance

Abstract

Photocatalysis is an essential branch in chemical catalysis research, in which the coupling of semiconductors to promote hydrogen production is one of the hot spots of photocatalysis. In recent decades, people's research on semiconductor materials has become perfect. Many studies have shown that coupling semiconductor-like materials such as MOFs with traditional semiconductor materials can often significantly improve photocatalysis. ZIF-67 and ZIF-67-L (Leaf) were embedded in Ni5Al4O11·18H2O using an in situ growth method. Nanoflower-hexagonal sheet and nanoflower-leaf hydrogen production systems were constructed, respectively. The results show that both systems have good hydrogen production capacity. ZIF-67 has a better specific surface area and microporous structure, so the hydrogen production performance of the hexagonal sheet structure under nanoflowers is the best, reaching 1629.3 μmol g−1 h−1.
