I've noticed that a common technique for creating a layer of oxide onto palladium or iridium is to dip it into high concentrated NaOH prior to putting it in a furnace for ~800C.

I've been reading numerous papers and it leads me to a textbook that I can't find accessible: Kauko, Y. and Knappsberg, L. (1939) Z. Elektrochem. 45, 760

The papers that I've been reading are W. T. Grubb and L. H. King, Analytical Chemistry 1980 52 (2), 270-273 DOI: 10.1021/ac50052a013



if anyone can help me solve this problem, I would be eternally grateful!
