The size of NiO, Pt, and Ni crystallites was estimated with the Scherrer equation using the full width at half-maximum (FWHM) of the NiO (200), Pt (111), and Ni (111) peaks (see Figure b, Table S3 ). There was a decreasing trend in the NPs’ average crystallite size with increasing milling intensity.
