Abstract

Glycerol is selectively converted to hydroxyacetaldehyde (HAA) and H₂ in aqueous solution on TiO₂-based photocatalysts. The product selectivity was verified to be strongly dependent on the facets of TiO₂. Rutile with high percentage of {110} facets results in over 90% superior selectivity of HAA, while anatase with {001} or {101} facets gives only 16% and 49% selectivity for HAA, respectively.
