abstract = {Electrocatalysis is at the heart of our future transition
to a renewable energy system. Most energy storage and
conversion technologies for renewables rely on
electrocatalytic processes and, with increasing availability
of cheap electrical energy from renewables, chemical
production will witness electrification in the near
future1,2,3. However, our fundamental understanding of
electrocatalysis lags behind the field of classical
heterogeneous catalysis that has been the dominating
chemical technology for a long time. Here, we describe a new
strategy to advance fundamental studies on electrocatalytic
materials. We propose to ‘electrify’ complex oxide-based
model catalysts made by surface science methods to explore
electrocatalytic reactions in liquid electrolytes. We
demonstrate the feasibility of this concept by transferring
an atomically defined platinum/cobalt oxide model catalyst
into the electrochemical environment while preserving its
atomic surface structure. Using this approach, we explore
particle size effects and identify hitherto unknown
metal–support interactions that stabilize oxidized
platinum at the nanoparticle interface. The metal–support
interactions open a new synergistic reaction pathway that
involves both metallic and oxidized platinum. Our results
illustrate the potential of the concept, which makes
available a systematic approach to build atomically defined
model electrodes for fundamental electrocatalytic studies.},
