The Work Function of Catalyst Films Deposited on Solid Electrolytes

The Work Function of Catalyst Films Deposited on Solid Electrolytes 

It has been found recently both theoretically and experimentally that  

Solid electrolyte cells can be used to alter significantly the work function e0 of the gas-exposed (i.e., catalytically active) catalyst-electrode surface by polarizing the catalyst/solid electrolyte interface. 

Solid electrolyte cells are work-function probes for the gas-ex-posed, catalytically active catalyst-electrode surfaces that is, the change A(e0) in catalyst surface average work function e0 is equal to eAVwR-The catalyst potential Vwr with respect to a reference electrode can be varied both by changing the gaseous composition and/or by polarizing the catalyst/solid electrolyte interface. 

We then concentrate on the meaning of that is, of the (ohmic-drop-free) potential difference between the catalyst film (W, for working electrode) and the reference film (R). The measured (by a voltmeter)
