Embodiment Construction

[0043] The porous poplar microstructure TiO of the present embodiment 2 Ceramic, its preparation method, comprises the following steps:

[0044] (1) Test material preparation

[0045] Three-year-old Populus × Euramericanacv. branches were taken from the forest farm of Anhui Agricultural University. After air drying, saw cut into circular slices. Add deionized water to the test material and boil it on an electric stove for 5 times, each time for 10 minutes. Remove the bark from the 3-year-old poplar branches, and remove some organic matter such as tannins from the branches. Put the test material into an oven and gradually raise the temperature to 103°C, and dry at a constant temperature of 103°C for 10 hours until the test material is absolutely dry.

[0046] (2) Benzyl alcohol extraction

[0047] Remove part of the fat content in the test material. Take out the dried test material, extract in 150ml benzene alcohol solution, the volume ratio of benzene alcohol is 95% CH 3...

Abstract

The invention discloses porous TiO2 ceramic adopting a poplar microstructure. The porous TiO2 ceramic adopting the poplar microstructure has the significance in that the application of poplar crotches is improved, more advanced technical reference is provided for impregnation of wood templates, the porous TiO2 ceramic adopting biological morphology and taking poplar crotches as the template is prepared with a two-step sol-gel impregnation and calcination method, and the porous TiO2 ceramic has lower density.

Description

technical field [0001] The invention belongs to the field of manufacturing milky white heat-resistant metal oxide microporous ceramic vessels, and in particular relates to TiO with porous poplar microstructure 2 ceramics. Background technique [0002] With the transformation of my country's forest resource structure, poplar, a fast-growing broad-leaved wood species with the characteristics of rapid growth, has become one of the preferred tree species for wood processing. However, poplar wood has defects such as soft material, unstable size and shrinkage, which seriously limit its application range. Poplar twigs are generally used as raw materials for biomass fuel, paper pulping and particleboard in wood processing. It has always been one of the goals pursued by wood and material researchers to develop new application fields of twigs and improve the utilization of twigs. one. [0003] Titanium dioxide (TiO 2 ) is a high-performance broadband semiconductor material. There ...
