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 WO3 nanostructured materials deposited on the wood substrate with diameters ranging from 100 to 150 nm were mainly responsible for the self-photodegradation of formaldehyde. Fe-doped WO3 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. (C) 2017 Elsevier B.V.
