Atomically controlled thin TiO2 layers were coated onto a carbon-supported Pt nanoparticle (Pt/C) surface using an atomic layer deposition (ALD) technique. Then, the resulting TiO2 coated Pt/C (ALD(TiO2)-Pt/C) was heat-treated at 150 °C under N2 atm

High-temperature calcination and reduction treatments of cobalt particles (17–20 nm) supported on TiO2 create cobalt particles covered with a TiOy layer. The layer thickness ranges from 2.8 to 4.0 nm. These phenomena, commonly called strong metal-s
