Preparation method of large-size block porous TiO2 with high specific surface area
The invention discloses a preparation method of large-size block porous TiO2 with a high specific surface area, which comprises the steps of firstly, smelting pure Ti and pure Cu metals into an alloy ingot by adopting a vacuum arc smelting technology, obtaining a large-size micron porous Ti structure with centimeter-level length and width, millimeter-level thickness and certain mechanical properties by utilizing a solid-phase dealloying method, then heating in a muffle furnace, oxidizing, and keeping the temperature for a period of time to finally obtain the large-size porous TiO2 with a macroscopic large size and good mechanical properties. The preparation method of the large-size block porous TiO2 with the high specific surface area is simple in preparation principle, easy to operate and low in cost.
本发明公开的是一种高比表面积的大尺寸块体多孔TiO2制备方法，首先是将纯Ti和纯Cu金属采用真空电弧熔炼技术熔炼成合金铸锭，利用固相去合金的方法，得到长、宽为厘米级，厚度为毫米级，且具有一定力学性能的大尺寸微米多孔Ti结构，然后再在马弗炉中加热，进行氧化，保温一段时间，最终得到具有宏观大尺寸，且力学性能良好的大尺寸多孔TiO2。本发明一种高比表面积的大尺寸块体多孔TiO2制备方法的制备原理简单，易操作且成本低。
