dc.description.abstract |
In the present work we investigate the utilization of Pt nanoparticles produced by atomic layer deposition (ALD) within anodic TiO2 nanotube (NT) layers for photocatalytic H2 production. By varying numbers of ALD cycles, Pt nanoparticles with different diameters, uniformly decorating the tube walls were produced. The Pt nanoparticle size (2-15 nm), the Pt mass loading and areal density were strongly dependent on the number of Pt ALD cycles. The deposited Pt nanoparticles turned out to be highly effective as co-catalyst for photocatalytic H2 generation. A most effective performance for solar light photocatalysis was reached after 26 ALD cycles (yielding an optimal areal coverage with particles of a diameter ≈ 7 nm). For UV light optimum photocatalytic efficiency was reached after 40 ALD cycles. |
