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
Interacting CoFe2O4 nanoparticles with different carbon materials for high performance oxygen evolution

Author: Munonde, Tshimangadzo S ; Nomngongo, PN ; Zheng, Haitao Date: Nov 2019 Electrocatalytic oxygen electrochemistry involving the conversion of H(sub2)O into O(sub2) has attracted considerable attention as a greener process for clean energy generation. However, the oxygen evolution reaction (that facilitates this ... 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
