Product Application
Catalytic Applications
It acts as an efficient catalyst for multiple chemical reactions. It is commonly used in the Haber process for ammonia synthesis and the industrial water–gas shift reaction. As a heterogeneous catalyst, it is applied in Fenton-type oxidation reaction for degrading rhodamine B. Besides, it can catalyze the oxygen reduction reaction (ORR) in anion exchange membrane fuel cells.
Medical Application
It is widely used as a magnetic resonance imaging (MRI) contrast agent in clinical and medical imaging fields.
New Energy Application
It can be utilized as a promising anode material for lithium-ion batteries, helping to improve the electrochemical performance of battery products.
