摘要

本文介绍了高硅多孔玻璃（pg）孔空间内表面各种酸碱位点（Brønsted碱、Brønsted酸、Lewis碱）含量的测定结果。高硅多孔玻璃（pg）是由双框架结构的碱硼硅酸盐玻璃在120-750℃的不同温度下通过等温暴露改性而获得的。分析了不同热处理温度下，所考虑的中心含量的变化与PG表面羟基化和去羟基化过程的关系。

Functional Composition of the Surface of Thermally Modified Porous Glasses

This paper presents the results of determining the content of various acid-base sites (Brønsted basic, Brønsted acid, Lewis basic) on the inner surface of the pore space of high-silica porous glasses (PGs), obtained as a result of the through leaching of alkali borosilicate glass with a two-frame structure and modified by isothermal exposure at various temperatures in the range of 120–750°C. The relationship between changes in the content of the centers under consideration and the processes of hydroxylation and dehydroxylation of the PG surface is analyzed depending on the heat treatment temperature.
