Products Features

Noble Metal Composite Catalytic Coating: Employs a nanoscale composite coating of ruthenium and platinum with precise thickness control at 0.5 microns. Ruthenium provides superior water oxidation activity, while platinum enhances hydrogen evolution stability and electron conduction. Their synergistic effect significantly lowers the activation energy barrier for overall water splitting.

3D Nano-Porous Conductive Architecture: The coating fully covers titanium fiber surfaces, forming a multi-level conductive network from macro-pores down to the nanoscale. This provides immense electrochemical active area while ensuring efficient mass transport of reactants and products within the three-dimensional space.

Exceptional Interfacial Stability: The ruthenium-platinum coating forms a robust interface with the titanium substrate through strong adhesion, effectively resisting catalyst layer delamination, corrosion, and active component dissolution under harsh conditions including acidic/alkaline electrolytes, high potential, and frequent start-stop cycles, ensuring long-term durability.

Optimized Gas-Liquid Transport Kinetics: Precisely tuned porosity and pore channel structure, combined with adjustable hydrophobic/hydrophilic coating surface properties, achieve balanced management of water, gas, and ion three-phase flow within the reaction zone. This effectively prevents gas blockage and facilitates rapid bubble detachment.
