This study focuses on using the thermal explosion method to synthesize intermetallic compounds (IMC) as precursors for dealloying, offering a straightforward, cost-effective approach to electrode material production. The rapid synthesis ensures uniform composition and structure, crucial for high-performance supercapacitors. We successfully synthesized porous CoAl IMC precursors, leading to Co₃O₄ materials with various nanostructures through combined chemical and electrochemical dealloying. These materials demonstrated exceptional pseudocapacitive performance, highlighting the potential of this synthesis approach for advanced energy storage solutions.
