Atomically dispersed Ni-N-C electrocatalysts, studied by Ni L-edge spectro-ptychography
Abstract
Soft X-ray spectro-ptychography of nickel-nitrogen-carbon electrocatalysts containing atomically dispersed Ni-based active sites were measured at the Ni L3 edge. Samples prepared with two different loadings of Ni precursors were investigated and compared to the results of an earlier study using scanning transmission X-ray microscopy (STXM) [Zhang et al., ACS Catalysis 12 (2022) 8746]. The ptychography data sets were measured using a defocused …
