High-Entropy Alloy Catalysts for Ammonia Decomposition
JHU Ref #: C15595
Value Proposition:
Unmet Need
Hydrogen storage and transportation remains a challenge for chemical transformation and energy-conversion systems. Ammonia has been utilized as a liquid fuel for storing hydrogen due to the decomposition of ammonia leading to carbon-free hydrogen. Ruthenium-based catalysts are the main element used for ammonia decomposition. However, Ruthenium is a scarce and costly metal thereby limiting its large-scale use. Therefore, there is a strong need for alloy catalysts made of Earth-abundant elements to be developed for ammonia decomposition.
Technology Description
Researchers at Johns Hopkins have developed high-entropy alloy nanoparticles that function as a catalyst for ammonia decomposition. This class of catalysts is made of the Earth abundant elements Fe, Ni, and Cu, with bimetallic Co-Mo catalytic centers for highly efficient decomposition of ammonia. In addition to high catalytic activity for ammonia decomposition these alloys remain stable when compared with Ruthenium and conventional Co-Mo catalysts.
Stage of Development
The technology has succeeded in proof-of-concept stages in lab-scale studies. The researchers are ready to scale up production.
