New catalysts could turn ammonia into clean energy more cheaply
Researchers have mapped a promising route to convert ammonia directly into usable energy using molecular catalysts—potentially offering a cheaper, more practical alternative to hydrogen for fuel cells. The approach could reshape how industries think about energy storage and transportation, opening a new market for ammonia-based power systems.
Originaltitel: The Potential of Molecular Electrocatalysis for Ammonia-to-Dinitrogen Conversion
<p>Electrochemical ammonia oxidation reaction (eAOR) regains interest due to ammonia being an interesting alternative to hydrogen for fuel cell technologies. In the present review, we first discuss some of the most important findings on eAOR with solid catalysts, including mechanistic and feasibility aspects for practical implementation. We then examine the reports on molecular catalysis of eAOR that have recently emerged. We finally discuss immobilization strategies of these molecular catalysts, and discuss intrinsic advantages of those strategies, so as to guide the design of efficient catalytic systems able to compete with heterogeneous, solid catalysts.</p>
