A rationally designed crystalline Ti 3+ core/amorphous Ti 4+ shell configuration can reverse the population disparity between holes and electrons reaching the surface of microsized rutile TiO 2 photocatalyst, thus significantly enhancing its photocatalytic activity by two orders of magnitude in terms of the hydrogen production rate under the irradiation of UV–vis light.
