A microporous structure (<I>d</I><SUB>pore</SUB> < 1 nm) of titanium oxide was synthesized by a salt catalytic sol–gel process of dilute titanium tetra-<I>n</I>-butoxide (Ti(<I>n</I>-C<SUB>4</SUB>H<SUB>9</SUB>O)<SUB>4</SUB>) and H<SUB>2</SUB>O solution without any template molecule. The specific surface area of titanium oxide after the calcinations at 300–350 °C was 310 m<SUP>2</SUP> g<SUP>−1</SUP>. It decreased significantly by calcinations above 400 °C because the microporous structure collapsed with crystallization into anatase.
