The impact of ultrasonic parameters on the exfoliation of NiFe LDH nanosheets as electrocatalysts for the oxygen evolution reaction in alkaline media

Author: Munonde, Tshimangadzo S ; Zheng, Haitao Date: Aug 2021 The ultrasonic process has been examined to exfoliate layered materials and upgrade their properties for a variety of applications in different media. Our previous studies have shown that the ultra-sonication treatment in water without chemicals ... Read more
Ultrasonic exfoliation of NiFe LDH/CB nanosheets for enhanced oxygen evolution catalysis

Author: Munonde, Tshimangadzo S ; Zheng, Haitao ; Nomngongo, PN Date: Dec 2019 The oxygen evolution reaction (OER) is an important reaction in water splitting. Nickel-iron layered double hydroxide (NiFe LDH) has been considered a potential catalyst for OER. Herein, we report a simple/green approach to improve the oxygen ... Read more
The ultrasonication boosts the surface properties of CoFe2O4/C nanoparticles towards ORR in alkaline media

Author: Matseke, Mphoma S ; Zheng, Haitao ; Wang, Y Date: Jun 2020 Since ultrasonication was reported to be used for exfoliation of layered materials in water (Science-ref. 31), the method has never been explored in non-layered materials, in particular, the effect of ultrasonication on the surface property ...
