WebFe-based catalytic sites for the reduction of oxygen in acidic medium have been identified by 57 Fe Mössbauer spectroscopy of Fe/N/C catalysts containing 0.03 to 1.55 wt% Fe, which were prepared by impregnation of iron acetate on carbon black followed by heat-treatment in NH 3 at 950 °C. WebLa masa atómica es la masa de un átomo, más frecuentemente expresada en unidades de masa atómica unificada. 1 La masa atómica es usada a veces incorrectamente como un sinónimo de masa atómica relativa, masa atómica media y peso atómico; estos últimos difieren sutilmente de la masa atómica. *La masa atómica está definida como la ...
