摘要
The influence of hydrogen on the microstructure of Pt films electrodeposited from a dinitrosulfatoplatinate(II) solution was investigated with thermal desorption spectroscopy, X-ray diffraction, transmission electron microscopy, and scanning electron microscopy. Two pronounced desorption peaks were observed in the thermal desorption spectrum of hydrogen from the Pt films. The total amount of desorbed hydrogen in the range from 300 to 1100 K in the atomic ratio (H/Pt) was 0.1. The deposited Pt film consisted of fine grains (similar to 10 nm) and many nano-voids. The lattice parameter of the Pt grains was lower than that of bulk Pt. Drastic grain growth and reduction in the lattice contraction occurred from heat treatment at a temperature corresponding to the first hydrogen desorption peak of 500 K.
