(a) Representation of the TiOx/ML support for XSW characterization. (b) Schematic of the spark ablation method for Co NP deposition on TiOx/ML. High voltage (HV) is applied to two Co electrodes in the presence of a carrier gas to induce spark discharge. The spark vaporizes some of the Co, forming an NP aerosol which is deposited on the sample by diffusion. AFM images of Co/TiOx/ML (c) in the pristine state and (d) after reduction at 600°C for 1 h. (e) Box charts showing the grain diameter distribution in the xy plane for the two model catalysts' surfaces.
