TY - T1 - The Effect of Atomic Layer Deposited Overcoat on Co-Pt-Si/gamma-Al2O3 Fischer-Tropsch Catalyst SN - / UR - http://hdl.handle.net/10138/332760 T3 - A1 - Heikkinen, Niko; Keskivali, Laura; Eskelinen, Patrik; Reinikainen, Matti; Putkonen, Matti A2 - PB - Y1 - 2021 LA - eng AB - Atomic layer deposition (ALD) was used to prepare a thin alumina layer on Fischer-Tropsch catalysts. Co-Pt-Si/gamma-Al2O3 catalyst was overcoated with 15-40 cycles of Al2O3 deposited from trimethylaluminum (TMA) and water vapor, followed by thermal annealing. The resulting tailored Fischer-Tropsch catalyst with 35 cycle ALD overcoating had increased activity compared to unmodified catalyst. The increase in activity was achieved without significant loss of selectivity towards heavier hydrocarbons...
