GL thanks Newton Advanced FellowshipA rationally designed crystalline Ti3+ core/amorphous Ti4+ shell configuration can reverse the population disparity between holes and electrons reaching the surface of microsized rutile TiO2 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.PostprintPeer reviewe
