Hydrogen embrittlement of high strength steel is seriously concerned and hydrogen visualization techniques in metals are strongly required to investigate the mechanism of hydrogen embrittlement. In this study, an in situ technique for hydrogen visualization in metals using aqua(2,2′-bipyridine-6,6′-dionato)(pentamethylcyclopentadienyl)iridium(III) (hereafter, Ir complex) has been developed. Hydrogen permeated through palladium-plated iron reacted with the Ir complex leading to the color change of the Ir complex. Furthermore, the flux of hydrogen could be quantitatively obtained from the changes in the RGB color values of the Ir complex. These results indicate that the Ir complex can be used for in-situ hydrogen visualization in metals.
