“…Pt nanothorns (Pt NT) were electrodeposited on a piece of carbon fiber paper (CFP, 1 cm × 1 cm) according to the method reported by Sun group and our previous work. , CFP was chosen as a substrate due to their high conductivity and large area. , Prior to electrodeposition, CFP was cycled ten times using cyclic voltammetry (CV) treatment ranging from −0.25 to 0.6 V at a scan rate of 50 mV/s. Electrodeposition was subsequently conducted in an aqueous solution of 2 mM H 2 PtCl 6 and 0.5 M H 2 SO 4 .…”

Valorization of biomass-derived carboxylic acids into drop-in fuels with the input of renewably sourced electricity is promising for a clean and sustainable energy future. Herein, self-supporting core–shell Pt@Ir nanothorns on 3D porous carbon fiber paper anodes have been employed for the electrocatalytic upgrading of carboxylic acids into fuel-range hydrocarbons. The core–shell anode is synthesized by electrodepositing Pt nanothorns on carbon fiber paper followed by galvanic deposition of a thin layer of Ir nanothorns on the surface. Pt@Ir exhibited a remarkably higher yield (49.5%) and Faraday efficiency (62.3%) for hydrocarbon production as compared to that of benchmark commercial Pt/C. The anode also has good recyclability with little activity loss after five successive runs.
