A　novel　strategy　for　the　synthesis　of　sintering-resistant　Pt/Ce-Ti-T　catalyst　with　high　activity　and　stability　for　water-gas　shift　(WGS)　reaction　is　demonstrated.　By　adding　dopamine　followed　by　thermal　treatment　under　an　inert　atmosphere,　the　Pt/Ce-Ti-T　catalyst　was　obtained　after　the　removal　of　sacrificial　dopamine　through　oxidation.　For　a　Pt/Ce-Ti　catalyst　subjected　to　ageing　but　without　the　participation　of　dopamine,　it　showed　a　sharp　decrease　of　CO　conversion　from　ca.　90%　to　48%　at　400　°C　within　12　h,　while　the　similarly　aged　Pt/Ce-Ti-T　catalyst　displays　a　CO　conversion　of　ca.　82%　and　no　obvious　sign　of　deactivation.　It　was　found　that　in　the　case　of　Pt/Ce-Ti,　there　was　increase　of　Pt　nanoparticle　size　from　7.25　to　20.72　nm,　while　there　was　no　significant　increase　in　the　Pt/Ce-Ti-T　case　(from　7.80　to　8.55　nm).　The　observation　can　be　associated　with　the　strengthening　of　metal-support　contact　as　a　result　of　dopamine　mediation.　The　outcome　is　enhanced　interfacial　bonding　between　Pt　nanoparticles　and　the　Ce-Ti　support,　making　the　Pt/Ce-Ti-T　catalyst　highly　resistant　to　sintering　and　has　commendable　durability　for　WGS　reaction.　©　2019
