The solar-driven transformation of alcohols into hydrogen and value-added products is a promising strategy for the green synthesis of fuels and fine chemicals. However, achieving these reactions via photocatalysts with efficient photo-adsorption and charge‑separation is challenging. Herein, a novel all-solid-state Z‑scheme catalyst was constructed. In this system, ZnIn₂S₄ nanosheets were grown in situ on the surfaces of CeO₂ nanorods. Such 2D/1D composites showing intimate contact can form solid Z-scheme heterostructures that combine the excellent visible-light absorption of ZnIn₂S₄ nanosheets, and the fast charge transport of CeO₂ nanorods, while retaining the strong reducibility of electrons in the CB of ZnIn₂S₄ nanosheets and the oxidizability of holes in the VB of CeO₂ nanorods. These synergistic advantages enhanced the photocatalytic performance, and the benzaldehyde and hydrogen yields reached 664.1 and 1496.6 μmol g_cat⁻¹. h⁻¹ respectively. Moreover, a high benzaldehyde selectivity was achieved. These findings provide new opportunities for application of hierarchical Z-scheme metal-oxide-based photocatalysts.

由太阳能驱动的将酒精转化为氢气和增值产品的方法，是绿色合成燃料和精细化学品的有前途的策略。但是，通过具有有效的光吸附和电荷分离功能的光催化剂实现这些反应具有挑战性。本文中，构建了一种新型的全固态Z型催化剂。在该系统中，ZnIn ₂ S ₄纳米片在CeO ₂纳米棒的表面上原位生长。这种显示紧密接触的2D / 1D复合材料可以形成固体Z型异质结构，结合了ZnIn ₂ S ₄纳米片的出色可见光吸收能力和CeO ₂的快速电荷传输能力纳米棒，同时保留ZnIn ₂ S ₄纳米片的CB中电子的强还原性和CeO ₂纳米棒的VB中的空穴的氧化性。这些协同优势增强了光催化性能，并且苯甲醛和氢气的产率分别达到664.1和1496.6μmolg _cat ^-1。h ^-1。此外，获得了高的苯甲醛选择性。这些发现为应用基于分层Z方案金属氧化物的光催化剂提供了新的机会。
