QUESTION 1 In a research center, a catalyst for CO2 reduction will be developed with AuCu based alloys. For this study, a device needs to be developed with catalyst material functioning with a certain electrical conductivity range. The researchers developed three different Au-Cu based alloys with compositions 10 at % Au and 90 at\% Cu, 45 at\% Au and 55 at\% Cu, and 65 at\% Au and 35 at\% Cu alloys. If the acceptable electrical conductivity of material is between 3.5106 and 8.5106 S/m, which alloy(s) can be used as a functional catalyst for CO2 reduction? Assume that the Nordheim coefficients are applicable to the given compositions. A) Show all calculations step by step for three of the alloy compositions. (20 points) B) Indicate and explain which alloy(s) can be functional for the selected application (5 points). Only use the necessary information: Resistivity of Gold =22.8nm, Resistivity of Copper =16.2nm, Atomic mass of Gold: 197g/mol, Atomic mass of Copper =63.55g/mol,1ohm.m=1m/S. =matrix+CX(1X) Table 2.3 Nordheim coefficient C (at 20C ) for dilute alloys obtained from I=CX and X
