barrier significantly decreased after Pt coating. The Pt shell with atomic monolayer
thickness showed the lowest CO oxidation energy barrier.
Elam et al. have fabricated Ru/Pt alloyed catalysts by alternately dosing Ru and
Pt precursors during ALD as shown in Fig. 3.6c [76]. The Ru/Pt ratio in the NPs
was tuned by controlling the ALD cycles of Ru and Pt precursors during ALD
process (Fig. 3.6d). Compared with Pt, Ru, as well as the physical mixture of Ru and
Pt nanoparticles (Fig. 3.6e), the Ru/Pt alloy was reported to have higher methanol
decomposition activity due to the electronic interaction between two elements. The
