Rational design of all-solid-state Z-scheme heterojunction with advanced structure is essential for boosting photocatalytic efficiency. Herein, we design and fabricate a novel Z-scheme photocatalyst with leaf architecture (named artificial leaf) via a simple dipping-calcination (DC) process followed by a successive ionic layer adsorption and reaction (SILAR) strategy. The prepared artificial leaf, composing of CdS, InVO, and BiVO, holds advanced leaf-like structure and Z-scheme electron transfer pathway. As a result, this novel artificial leaf exhibits outstanding capability for the harvesting of visible light and superior efficiency for the separation of photogenerated electron-hole pairs, as well as remarkably enhanced photocatalytic performance and stability for H evolution (with the rate of 5033 μm g∙h) and pollution degradation (46% pollution can be degraded within 3 h).
合理设计具有先进结构的全固态 Z 型异质结对于提高光催化效率至关重要。本文通过简单的浸渍-煅烧（DC）工艺和随后的连续离子层吸附和反应（SILAR）策略，设计并制备了一种具有叶状结构（命名为人工叶）的新型 Z 型光催化剂。所制备的人工叶由 CdS、InVO 和 BiVO 组成，具有先进的叶状结构和 Z 型电子转移途径。因此，这种新型人工叶具有出色的可见光捕获能力和优异的光生载流子分离效率，以及显著增强的光催化析氢性能和稳定性（速率为 5033 μm g·h）以及污染降解（在 3 h 内可降解 46%的污染）。
