Author:Motsoeneng, RG; Modibedi, Remegia M; Mathe, Mahlanyane K; Khotseng, LE; Ozoemena, KIDate:Sep 2015Surface-limited redox replacement reactions using the electrochemical atomic layer deposition (EC-ALD) technique were used to synthesize PdPt bimetallic electrocatalysts on carbon paper substrate. Electrocatalysts having different Pd:Pt ratio ...Read more
Author:Matseke, Mphoma S; Zheng, Haitao; Wang, YDate:Jun 2020Since 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 ...Read more
Author:Matseke, Mphoma S; Luo, Hongze; Wen, L; Zheng, HaitoDate:Jun 2022NiFe2O4 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
