WebAug 30, 2024 · Abstract. Bismuth-based solar absorbers have recently attracted attention as a result of the similarities between the bismuth halides and lead hybrid perovskites [ 1, 2, 3 ]. Both bismuth and lead adopt oxidation states two lower than their group valence, resulting in a stable d^ {10}s^2p^0 electronic configuration. Download chapter PDF. WebThe Bi–Ni catalyst required overpotentials of 56 mV and 183 mV at 10 mA cm −2 for the hydrogen evolution reaction (HER), which were close to that of commercial Pt/C in 1.0 M KOH and 1.0 M PBS (pH 7.0), respectively. The electrocatalyst maintained a steady current density during 20 h electrolysis in 1.0 M KOH and 1.0 M PBS (pH 7.0).
