Scholarcy highlights

  • Commercial and home prepared bare and Pt-supported TiO2 samples were used as the photocatalysts for the aqueous photo-conversion of glucose at ambient pressure and temperature
  • Aerobic and anaerobic conditions were used to study the products of glucose degradation both in the liquid and gaseous phases
  • The distribution of these molecules was different in the presence of the various powders, depending on the structural and physico-chemical properties of the materials, and Pt resulted essential for the anaerobic production of H2
  • The home prepared samples resulted more active than the commercial ones
  • The rutile and brookite polymorphs were the most active samples both for glucose conversion and H2 formation
