Fig. 13. (a) Yield rate of NH3 at a potential of −0.2 V versus RHE; (b) yield of NH3 (olive) and faradaic efficiency (red) against the catalytic temperature under atmospheric pressure at −0.2 V versus RHE; (c) yield of NH3 (olive) and faradaic efficiency (red) against the catalytic temperature under a N2 flow rate at −0.2 V versus RHE; error bars in (b) and (c) represent the standard deviations of three independent measurements of the same sample; (d) proposed pathway for the NH3 synthesis using the Au/TiO2. catalyst.
