The　selective　immobilization　of　noble　metals　right　at　the　place　where　photogenerated　electrons　migrate　through　the　photodeposition　approach　is　a　unique　strategy　to　load　cocatalysts　on　semiconductors　for　solar　hydrogen　production.　However,　a　poor　metal-semiconductor　interaction　is　often　formed,　which　not　only　hinders　the　interfacial　charge　transfer,　but　also　results　in　the　easy　aggregation　and　shedding　of　cocatalysts　during　photocatalytic　reactions.　Herein,　it　is　demonstrated　that　the　photodeposited　ultrafine　metals,　such　as　nanosized　Au,　can　be　well　stabilized　on　TiO2　nanocrystallines　without　sintering　by　employing　a　sacrificial　carbon　coating　annealing　strategy　to　strengthen　the　metal-support　interaction.　Benefiting　from　the　improved　interfacial　contact　between　Au　and　TiO2　for　fast　charge　transfer　and　the　well-preserved　size-dependent　catalytic　behavior　of　Au　nanoparticles　toward　hydrogen　evolution　reaction,　the　annealed　Au/TiO2　exhibits　a　significant　enhanced　activity　toward　photocatalytic　H-2　production　with　good　durability.
