“…Optimization of the electrodeposition method usually focuses on the usage of different aqueous and/or organic electrolyte solutions (Hallstadius, 1984;Ingelbrecht et al, 1997;Jobbágy et al, 2013;Kressin, 1977;Lee and Lee, 2000;Puphal and Olsen, 1972;Talvitie, 1972;Torrico et al, 2015) or on the improvements made on the system itself (e.g. the usage of rotating disc cathodes (Tsoupko-Sitnikov et al, 2000), semipermeable membranes to prevent platinum precipitation (Ferrero Calabuig et al, 1998), introduction of external equipment to improve the stirring of the electrolyte solution in a conventional electrodeposition cell (Jobbágy et al, 2013;Panta et al, 2010)). All the parameters that influence the electrodeposition yield and the source quality (chemical composition of the electrolyte solution, applied current/voltage, electrodeposition time, pH of the electrolytic solution, distance between the electrodes, electrolyte volume) need to be adjusted whenever such modifications are made.…”
