In Situ Synthesis of TiO2 Nanoparticles in Xylem Cell of Living Trees under Ambient Temperature
Titanium dioxide nanoparticles were produced in xylem cell of living tree by in situ hydrolysis of tetrabutyl orthotitanate (TBOT) under ambient pressure and temperature. The specimens were characterized using Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Analysis (EDXA) and X-ray powder Diffraction (XRD) spectroscopy. From these results, spherical and uniform dispersion particles in nanoscale and anatase TiO2 crystalline phase presence in xylem cell wall of Populus ussuriensis. This work demonstrates that it is possible to generate of wood-nano biological composite material in xylem cell of living tree.
