摘要：
The high-temperature electrochemical dealloying of the PdIn intermetallic in the LiCl-KCl eutectic at the temperature of 450 & DEG;C in potentiostatic mode was carried out. The resulting formation of bi-continuous nano-porous structures with different residual indium content was analyzed at time intervals of 40, 120 and 300 min from the start of the dealloying process. Our results demonstrate that specific bi-continuous structures with a pore size of the order of 100 nm are formed while the temperature of electrolysis is maintained close to the temperature of palladium recrystallization. If the dealloying process is continued for 5 h it is possible to obtain a pure intermetallic Pd2In compound in nanoporous state.& COPY; 2022 Hydrogen Energy Publications LLC.
