In this paper, solid wood with superior self-photodegradation of formaldehyde (HCHO) under visible-light was realized through a facile method at room temperature. Spherical Fe-doped WO nanostructured materials deposited on the wood substrate with diameters ranging from 100 to 150nm were mainly responsible for the self-photodegradation of formaldehyde. Fe-doped WO nanostructured materials were strongly adhered to wood surface through electrostatic and hydrogen bonding interactions. Additionally, the dimensional stability and the inherent anisotropic thickness swelling of wood were greatly improved and eliminated, respectively. Interestingly, a wood rabbit craft was also designed and showed a good visible-light-driven photocatalytic performance in a relatively larger area for different concentrations of HCHO. The research result would both fabricate a novel catalyst for the degradation of the hazardously gaseous pollutants and basically improve the wood intrinsic performance.
本文通过简便的室温方法实现了具有优异可见光下甲醛（HCHO）自降解性能的实木。在木质基材上沉积的直径为 100 至 150nm 的球形 Fe 掺杂 WO 纳米结构材料主要负责甲醛的自降解。Fe 掺杂 WO 纳米结构材料通过静电和氢键相互作用牢固地附着在木材表面。此外，还极大地提高和消除了木材的尺寸稳定性和固有的各向异性厚度膨胀。有趣的是，还设计了一个木制兔子工艺品，并在相对较大的区域内展示了良好的可见光驱动光催化性能，可用于不同浓度的 HCHO。研究结果将为危险气体污染物的降解制造一种新型催化剂，并从根本上改善木材的内在性能。
