Electrocatalytic performance of Co-doped NiFe2O4/C nanoparticles towards oxygen reduction reaction in alkaline media

Author: Matseke, Mphoma S ; Zheng, Haitao ; Mallick, Kaushik Date: Nov 2019 Spinel metal oxides with the general formula of AB(sub2)O(sub4) have attracted a lot of attention over the past few decades as promising cathode materials for oxygen reduction reaction (ORR) in fuel cells. This is due to their changeable ... Read more
A green approach for enhancing the electrocatalytic activity and stability of NiFe2O4/CB nanospheres towards hydrogen production

Author: Munonde, Tshimangadzo S ; Zheng, Haitao ; Matseke, Mphoma S ; Nomngongo, PN ; Wang, Y ; Tsiakaras, P Date: Mar 2020 Among the exfoliation processes applied on layered materials, it is the first time to explore the ultrasonic exfoliation in water for improving the catalytic properties of NiFe(sub2)O(sub4)/CB (CB = carbon black) nanospheres towards the ...

Ni-doped CoFe2O4/C nanoparticles as efficient catalysts for ORR in alkaline media

Author: Matseke, Mphoma S Date: Aug 2019 This presentation discusses the Ni-doped CoFe2O4/C nanoparticles as efficient catalysts for ORR in alkaline media. Read more
Oxygen reduction reaction catalyzed by Ni doped CoFe2O4 /C nanoparticles in alkaline media

Author: Matseke, Mphoma S Date: Oct 2019 The main aim of this work was to synthesize carbon supported CoFe(sub2-x) Ni(subx)o(sub4) nanoparticles with high catalytic activity for ORR in alkaline media 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 ...

The upgraded performance of the NiFe2O4 /C electrocatalyst using Co substitution for the oxygen reduction reaction in an alkaline solution

Author: Matseke, Mphoma S ; Luo, Hongze ; Wen, L ; Zheng, Haito Date: Jun 2022 NiFe2O4 is one of the most abundant and inexpensive spinels; however, its activity toward the oxygen reduction reaction (ORR) is relatively low. For the first time, Co-substituted Fe partly of the NiFe2O4 electrocatalyst was studied to improve ... Read more
