AI Technical Summary
In existing oil fume purification technologies, catalysts are prone to sintering, coking, and deactivation due to uneven local heating, and low-temperature plasma-catalytic oxidation methods may generate secondary pollutants.
Nickel-iron-based electrothermal catalysts were prepared by electrodeposition. Fe3+, Ni2+ and cyanuric acid were deposited on the surface of nickel foam to form an iron-nickel organic framework material. The three-dimensional network porous structure of NiFe2O4 and Fe1Ni1-CA was generated by air calcination. The catalytic activity was improved by the electrothermal synergistic catalytic mechanism.
It achieves efficient oil fume purification of catalyst, avoids deactivation caused by uneven local heating, and improves catalytic activity through adsorption oxygen and lattice oxygen regulation mechanisms, thereby reducing the risk of secondary pollution.
