Abstract

Strained metal oxides are known to exhibit improved activity for redox and photocatalytic reactions. Here, we intentionally introduced tensile strain into rutile-type TiO₂ by utilizing the difference in thermal expansion coefficients between TiO₂ and Au and applied it as a solid acid catalyst. It was demonstrated that its acid catalytic activity in the acetalization of furfural was enhanced by increasing the degree of the strain introduced.
