Long-range disordered MoO2 with rich oxygen vacancies for high-rate and durable lithium storage

Rational synthesis of 3D coral-like ZnCo2O4 nanoclusters with abundant oxygen vacancies for high-performance supercapacitors

“…21 Liu et al successfully synthesized the long-range disordered MoO 2 with rich oxygen vacancies, exhibiting an impressive specic capacity of 1631.3 mA h g −1 at a current density of 0.2 A g −1 and demonstrating excellent rate capability (592.6 mA h g −1 at 8.0 A g −1 ). 22 The strategies for inducing oxygen vacancies primarily revolve around hydrogen treatment, 23 post-annealing in oxygen-decient atmospheres, 24 ion doping, 25 or electron irradiation. 26 However, the aforementioned strategies oen exhibit drawbacks such as high risks of hydrogen explosion, elevated temperature conditions, low efficiency, and intricate experimental procedures, thereby impeding the implementation of introducing oxygen vacancies in transition metal oxides.…”
