Supported NI-M Materials for Electrooxidation of Hydrazine

CTCN Keyword Matches

Nickel and its intermetallics/alloys with other metals are well known materials for electrooxidation of hydrazine. Nickel is unique element that has an electronic structure that allows it to behave as “noble” element for example to be active in the reaction of electrooxidation of different fuels. However in fuel cell operations unsupported nickel based materials possess a number of disadvantages in electrooxidation of hydrazine. The main drawbacks are low catalytic surface utilization small amount of active sites and high rate of ammonia production. Thus there is a need for a process that supports nickel based materials and addresses these issues to enable effective use in fuel cell operations. Technology Description: Researchers at the University of New Mexico have developed methods of preparation by different synthetic approaches of highly active supported Ni-M catalysts. The metals or alloys can be either solid solutions or single phases or mixture of phases. Supported Ni-M catalysts are highly active in reaction of electrooxidation of hydrazine durable and inexpensive to manufacture. Applications: Fuel cell applications


1) Durable 2) Inexpensive to manufacture 3) Highly active in reaction of electrooxidation of hydrazine 4) Increased stability and activity
