Abstract
Noble metals in form of bulk materials are rarely used as catalysts in industrial applications due to their price and limited accessibility. However, the surface of commonly-used materials can be modified with an exceptionally low amount of platinoids to enhance their electrochemical activity. In this work, the surface of the free-standing nanoconical Ni structures was modified with a thin metallic rhodium layer with a spontaneous galvanic displacement process. It emerged that Rh-decorated Ni nanoconical electrodes exhibited higher catalytic activity in a model hydrogen evolution reaction in an alkaline environment in comparison to the unmodified electrode. Furthermore, the proposed synthesis protocol is high-speed and straightforward, making it promising in application on a semi and industrial scale. Linear Sweep Voltammetry measurements were used to test the catalytic activity in 1 M NaOH electrolyte. The nanoconical structures were highly-hydrophobic, what has been observed by dedicated camera-based equipment. In addition, the electrochemically-active surface area (ECSA) of tested electrodes were estimated and confirmed in atomic force microscope AFM measurements. The durability of coatings was tasted in 1 M NaOH for 14 days.
