Effect of atomic-layer-deposited TiO2 on carbon-supported Ni catalysts for electrocatalytic glycerol oxidation in alkaline media |
| 초록 |
Thin TiO2 layers were deposited onto carbon supported Ni catalysts (Ni/C) through atomic layer deposition (ALD) and the resulting TiO2-coated Ni/C (ALD(TiO2)-Ni/C) was utilized for electrochemical glycerol oxidation in alkaline media. X-ray photoelectron spectroscopy analysis demonstrated that the Ni surface phase of ALD(TiO2)-Ni/C mainly consisted of Ni(OH)2 while that of uncoated Ni/C was a mixed phase of NiO and Ni(OH)2. The ALD(TiO2)-Ni/C exhibited at least 2.4 times higher electrocatalytic activity than that of Ni/C. Density functional theory calculations were applied to investigate how the modified Ni surface with the TiO2 coating affects the adsorption/desorption properties of glycerol. |
