Palladium Based Catalyst For Co2 Reduction With High Co Tolerance

Brief Description

An innovative Palladium hydride catalyst that significantly enhances the electroreduction of carbon dioxide (CO2) to formate with exceptional tolerance for carbon monoxide (CO).

Full Description

This technology introduces a hydrogen-rich Palladium (Pd) hydride catalyst, synthesized through a one-step solvothermal process for the electrocatalytic reduction of carbon dioxide (CO2). This catalyst surpasses commercial Pd catalysts in its efficiency and lifetime, setting a new benchmark for Pd-based catalysts in CO2 capture and conversion. The superior performance of this catalyst is attributed to its high carbon monoxide (CO) tolerance, which is crucial for maintaining long-term activity and selectivity.

Suggested uses

• Environmental technology for CO2 capture and conversion. 
• Manufacture of formic acid, acetate, oxalate, and other valuable chemicals. 
• Renewable chemical synthesis and green energy storage solutions. 
• Industrial processes requiring high-efficiency CO2 conversion technologies.

Advantages

• Exceptional faradaic efficiency of 93.1% towards formate production. 
• Record-setting working lifetime of 4 hours, surpassing current commercial catalysts. 
• High tolerance to CO, overcoming a common limitation of Pd-based catalysts. 
• Derived from a straightforward one-step solvothermal synthesis. 
• Applicable for a wide range of CO2 electroreduction products beyond formate.
