摘要: Abstract Photoemission electron microscopy (PEEM) was used as spatially resolving method to explore the effect of electrochemical pumping with a positive voltage porous platinum electrodes interfaced working electrode yttrium stabilized zirconia (YSZ). The experiments were conducted under UHV conditions (p ≈ 10−9 mbar). In PEEM uniform rapid darkening Pt surface observed during anodic polarization followed by appearance bright spots on dark background. in images are due reduction around electrically isolated islands.
