Thin Film Catalyst

In this study, aged Co–Mo (3:10) alloy film has been demonstrated as an efficient and durable catalyst for hydrogen evolution reaction (HER) in acidic solution. The Co–Mo alloy films with varying Co/Mo atomic ratios have been deposited by magnetron sputtering. The catalytic activity of Mo film is outperformed by the Co–Mo alloys, among which the Co–Mo (3:10) alloy exhibits the highest HER activity with an overpotential of 310 mV at 10 mA cm[Formula: see text] current density, exchange current density of 1.74 × 10[Formula: see text] A cm[Formula: see text] and a Tafel slope of 61 mV dec[Formula: see text]. Combined with the good stability provided by the surface oxide layer, the aged Co–Mo (3:10) alloy is a promising catalyst for HER in acidic solutions.

Методами поляризационных и импедансных измерений изучена кинетика реакции выделения водорода на MnSi-электроде в сернокислых растворах с различной концентрацией ионов водорода. Сделано предположение о механизме выделения водорода на силициде. Отмечено влияние тонкой оксидной пленки на кинетику выделения водорода на MnSi при невысоких катодных поляризациях.       REFERENCES Rotinyan A. L., Tikhonov K. I., Shoshina I. A.
