Linear combination of time-resolved XANES data: (a) linear combination of the curve measured at t = 6.3 s using a linear combination of Pt4+ (μ4+) and Pt0 (μ0) XANES spectra. (b) The resulting temporal evolution of the Pt0 fraction during Pt NP synthesis. The inset shows the same curve plotted on linear–log scale, and the solid line corresponds to the best algebraic fit to 0.538 (1) + 0.044 (2) log(t). |
