Capacitance of MnO2 Micro-Flowers Decorated CNFs in Alkaline Electrolyte and Its Bi-Functional Electrocatalytic Activity toward Hydrazine Oxidation

Ji, Seong-Min; Ghouri, Zafar Khan; Elsaid, Khaled; Ko, Yo Han; Al-Meer, Saeed; ... more authors ... less authors ( ESG , 2017 , Article)

Well-dispersed MnO2 micro-flowers were grown directly on carbon nanofibers via a simple hydrothermal technique without any template. Structure and morphology were characterized by X-ray diffraction (XRD) and field-emission ...

ZnO@C (core@shell) microspheres derived from spent coffee grounds as applicable non-precious electrode material for DMFCs

Ghouri, Zafar Khan; Al-Meer, Saeed; Barakat, Nasser A. M.; Kim, Hak Yong ( Nature Publishing Group , 2017 , Article)

Although numerous reports have introduced non precious electrocatalysts for methanol oxidation, most of those studies did not consider the corresponding high onset potential which restricts utilization in real fuel cells. ...

Synthesis and Physicochemical Studies of Perovskite Manganite La0.8Ca0.2Nn1−xCoxO3 (0 ≤ x ≤ 0.3)

Turki, D.; Ghouri, Zafar Khan; Al-Meer, Saeed; Elsaid, Khaled; Ahmad, M.I.; ... more authors ... less authors ( The Korean Magnetics Society , 2017 , Article)

The physicochemical properties of La0.8Ca0.2Mn1−xCoxO3 nanopowders as a function of Co content (x) have been investigated. La0.8Ca0.2Mn1−xCoxO3 nanopowders were synthesized by sol-gel method and morphologically and ...

Critical Behavior of La0.8Ca0.2Mn1−xCoxO3 Perovskite (0.1 ≤ x ≤ 0.3)

Turki, Dorra; Ghouri, Zafar Khan; Al-Meer, Saeed; Elsaid, Khaled; Ahmad, M.I.; ... more authors ... less authors ( MDPI , 2017 , Article)

The critical properties of La0.8Ca0.2Mn1−xCoxO3 (x = 0, 0.1, 0.2 and 0.3) compounds were investigated by analysis of the magnetic measurements in the vicinity of their critical temperature. Arrott plots revealed that the ...

Applicable anode based on Co3O4–SrCO3 heterostructure nanorods-incorporated CNFs with low-onset potential for DUFCs

Ghouri, Zafar Khan; Elsaid, Khaled; Al-Meer, Saeed; Barakat, Nasser A.M. ( Springer , 2017 , Article)

Besides the high-current density, lower onset potential of urea electrooxidation is key parameter which influences the direct urea fuel cell performance. In the present article, low-onset potential has been reported for ...

Engineering of magnetically separable ZnFe2O4@ TiO2 nanofibers for dye-sensitized solar cells and removal of pollutant from water

Al-Meer, Saeed; Ghouri, Zafar Khan; Elsaid, Khaled; Easa, Ahmed; Al-Qahtani, Muneera Th.; ... more authors ... less authors ( Elsevier , 2017 , Article)

Abstract In this study, magnetic Zinc Ferrite (ZnFe2O4)@TiO2 nanofibers were prepared by low cost and nontoxic route; hydrothermal technique followed by electrospinning process. The prepared magnetic ZnFe2O4@TiO2 nanofibers ...
