Electrode Design for Durable and Energy-Dense Rechargeable Zinc-Air Batteries
(University of Waterloo, 2020-01-21)Zinc-air batteries have been proposed as a low-cost and energy-dense candidate to replace or supplement lithium-ion batteries in electric vehicles. This thesis explores the viability of zinc-air batteries in electric ... -
Embellished hollow spherical catalyst boosting activity and durability for oxygen reduction reaction
(Elsevier, 2018-09)Transition metals hybridized to heteroatom doped carbon material can be regarded as the most promising non-noble candidate for boosting the sluggish kinetics of oxygen reduction reaction (ORR). However, it has always been ... -
Nanostructured oxygen reduction catalyst designs to reduce the platinum dependency of polymer electrolyte fuel cells
(University of Waterloo, 2015-07-24)Polymer electrolyte fuel cells (PEFCs) are electrochemical devices that efficiently convert hydrogen and oxygen into electricity and water. Their clean point of operation emissions and fast refueling times have resulted ... -
Nitrogen-Doped Carbon Nanotubes and their Composites as Oxygen Reduction Reaction Electrocatalysts for Low Temperature Fuel Cells
(University of Waterloo, 2011-05-03)The extensive amount of platinum required in order to facilitate the oxygen reduction reaction (ORR) occuring at the cathode of low temperature fuel cells provides cost limitations to the sustainable commercialization of ...
