Product Overview
DiffuCarb™ E411 · Bi-Based Composite · Carbon Paper Cathode · CO₂ → HCOOH
DiffuCarb™ E411 Bi-Based Composite - Carbon Paper Electrode for three-chamber solid-state formic-acid electrolyzers is a cathode electrode platform developed for electrochemical conversion of CO₂ to formic acid. Accelerate® Bi-based composite material provides the main catalytic interface, while porous carbon paper provides electronic conduction, gas diffusion and mechanical support.
According to the supplied product description, Bi and Bi-based composite materials provide high selectivity and Faradaic-efficiency positioning for CO₂RR toward formic acid. Their larger active surface area and abundant active sites can support CO₂ adsorption, electron transfer and target-product formation. The three-chamber solid-state electrolyzer further helps separate reactants and products, supporting formic-acid purity and overall process stability.
