scanning tunneling microscopy studies of carbonate-induced restructuring of Ag-decorated Cu(100) electrodes.

Ag-decorated Cu electrocatalysts are of great interest for electrochemical CO reduction, because of an increased yield of multi-carbon products. Here, we present studies of well-defined AgCu electrodes by scanning tunneling microscopy. These bimetallic model electrocatalysts are prepared by electrodepositing submonolayer Ag coverages on Cu(100) in 0.

Structure of the (Bi)carbonate Adlayer on Cu(100) Electrodes.

(Bi)carbonate adsorption on Cu(100) in 0.1 M KHCO has been studied by in situ scanning tunneling microscopy. Coexistence of different ordered adlayer phases with ( ×6 )R45° and (4×4) unit cells was observed in the double layer potential regime.

Molybdenum tricarbonyl complex functionalised with a molecular triazatriangulene platform on Au(111): surface spectroscopic characterisation.

Transition metal complexes form the basis for small molecule activation and are relevant for electrocatalysis. To combine both approaches the attachment of homogeneous catalysts to metallic surfaces is of significant interest. Towards this goal a molybdenum tricarbonyl complex supported by a tripodal phosphine ligand was covalently bound to a triazatriangulene (TATA) platform via an acetylene unit and the resulting TATA-functionalised complex was deposited on a Au(111) surface.

The Dynamic Nature of CO Adlayers on Pt(111) Electrodes.

CO adlayers on Pt(111) electrode surfaces are an important electrochemical system and of great relevance to electrocatalysis. The potential-dependent structure and dynamics of these adlayers are complex and still controversial, especially in the CO pre-oxidation regime. We here employ in situ high-speed scanning tunneling microscopy for studying the surface phase behavior in CO-saturated 0.
