The TiO 2 /wood (TW) based on fast-growing poplar wood was in situ synthesized through one-step solvothermal method and then Ag-doped TiO 2 /wood (ATW)was also prepared via the solvothermal method. The morphologies, crystal structure, and chemical characteristics of the composites were carried out by SEM, XRD, XPS and FTIR. The results of XPS and FTIR showed that the nanoparticles (TiO 2 and Ag) were chemically bonded to the wood surface through the combination of hydrogen groups. Spherical-like Ag nanoparticles (Ag-NPs) was about 66 nm diameter. What’s more, the TW and ATW showed excellent antibacterial against Gram positive and negative bacterium under visible light irradiation and mould-resistance properties, which illustrated a significance and practical value in high added-value of wood.
