Oxygen reduction reaction on a highly-alloyed Pt-Ni supported carbon electrocatalyst in acid solution

Author: Zheng, Haitao ; Rohwer, Mark B ; Mathe, Mahlanyane K Date: 31 Aug 2010 Alloyed electrocatalysts such as PtNi/C[1-2], PtCo/C[3], PtCr/C[4], PtFe/C [5-6], and non-alloyed Pt-TiO2/C were reportedly investigated for methanol tolerance during Oxygen reduction reaction (ORR). The high methanol tolerance of these ... Read more
Preparation and characterisation of porous poly(2,5benzimidazole) (ABPBI) membranes using surfactants as templates for polymer electrolyte membrane fuel cells

Author: Zheng, Haitao ; Petrik, L ; Mathe, Mahlanyane K Date: Apr 2010 The first instance synthesis of porous poly(2,5benzimidazole) (ABPBI) membranes using sodium dodecyl sulfate (SDS) surfactants as templates is reported. The membranes were characterised by SEM, TGA, DSC and tensile tests. The tensile test ... Read more
Printed paper–based electrochemical sensors for low-cost point-of-need applications

Author: Smith, Suzanne ; Madzivhandila, Phophi ; Ntuli, Letta ; Bezuidenhout, Petrone H ; Zheng, Haitao ; Land, Kevin J Date: Feb 2019 Paper-based microfluidics is a rapidly developing field with applications for point-of-care disease and environmental diagnostics. In parallel, printed electronics has grown swiftly, particularly for wearable technologies. By combining these ... Read more
Solid coated Li4Ti5O12 (LTO) using polyaniline (PANI) as anode materials for improving thermal safety for lithium ion battery

Author: Mo, L ; Zheng, Haitao Date: Nov 2020 In generally, the thermal behaviour of cathode and electrolyte are the major concerns for the safety of lithium-ion battery, In contrast to rare attention on thermal effects of anode materials. In this work, Li4Ti5O12/polyaniline (PANI@LTO) ... Read more

Thermal conductivity and stability of nano size carbon black filled PDMS: Fuel cell perspective

Author: Chen, H ; Botef, I ; Zheng, Haitao ; Maaza, M ; Vasudeva Rao, V ; Srinivasu, VV Date: 2011 Carbon black filled Polydimethylsiloxane (PDMS) was considered as a prospective bipolar plate material candidate for a Fuel Cell. In this perspective, thermal conductivity and stability of the composites were investigated. Samples with filler ... Read more
The thermal kinetics of methanol oxidation on Pt/MWCNT electrocatalysts in alkaline media

Author: Zheng, Haitao ; Modibedi, Mmalewane Date: Sep 2023 In this study, the thermal electrooxidation of methanol on a Pt/MWCNT catalyst was examined in alkaline media across the temperature range of 298-363 K. The investigation utilized cyclic voltammetry (CV), quasi-state polarization, and ... 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
Ultrasonic exfoliation of NiFe LDH/CB nanosheets/few layered sheets for enhanced oxygen evolution electrocatalysis

Author: Tshimangadzo, Munonde S ; Zheng, Haitao ; Nomngongo, PN Date: Aug 2019 This presentation discusses the ultrasonic exfoliation of NiFe LDH/CB nanosheets/few layered sheets for enhanced oxygen evolution electrocatalysis. 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 ...
