Selectively coupling Ru single atoms facilitating methanol oxidation reaction

Direct methanol fuel cells (DMFCs) are highly sensitive to CO poisoning on the current Pt based anode at operating condition. In a paper recently published in Angewandte Chemie International Edition, Kong et al. and coworkers presented a precise position control of single atom via atomic layer deposition (ALD) to synthesis the selective deposition of Ru single atoms (SAs) on the concavities of corrugated PtNi nanoparticles (Ru-ca-PtNi), which exhibited high activity and stability for methanol oxidation reaction (MOR).
