| Abstract Scope |
Platinum black is a nanostructured catalytic material with exceptional electrocatalytic activity and high surface area, making it ideal for enhancing electrochemical processes. However, its high cost limits widespread use in bulk form. A promising and cost-effective alternative involves modifying titanium surfaces through the electrodeposition of platinum black, combining the catalytic performance of platinum with the durability and chemical resistance of titanium. This work presents a thermodynamic and kinetic study of platinum black electrodeposition onto titanium substrates using PtCl₄ as a precursor. The objective is to understand the nucleation and growth mechanisms, and to optimize the deposition parameters to obtain uniform, adherent, and nanostructured coatings. The findings provide valuable insight into the formation process of platinum black films and contribute to the development of efficient and stable Pt/Ti electrodes. These electrodes have potential applications in aggressive electrochemical environments and support the advancement of sustainable electrochemical technologies. |
