Laser-induced oxygen vacancies in FeCoO nanoparticles for boosting oxygen evolution and reduction

FeCo 2 O 4 nanoparticles with abundant oxygen vacancies were produced by laser fragmentation. The oxygen vacancies can lower the thermodynamic energy barriers as well as accelerate the electron transfer, eventually promoting oxygen evolution and reduction reactions simultaneously. Abundant oxygen va...

Description
Summary:FeCo 2 O 4 nanoparticles with abundant oxygen vacancies were produced by laser fragmentation. The oxygen vacancies can lower the thermodynamic energy barriers as well as accelerate the electron transfer, eventually promoting oxygen evolution and reduction reactions simultaneously. Abundant oxygen vacancies are successfully introduced into NiFe 2 O 4 nanoparticles by laser fragmentation, resulting in dramatic improvement of catalytic activities for oxygen evolution and reduction.
