Guest lecture prof. dr. Kenneth Ozoemena at MOBI

Prof. dr. ir Noshin Omar invited a special guest lecturer from the University of Witwatersrand, Johannesburg (SA). On Friday, 1 December 2017 (9h00 – 11h00), prof. dr. Kenneth Ozoemena will present his latest research on the next generation materials for batteries.

Entrance to the lecture is open, so you are all welcome to joins us!

The location is VUB Campus Etterbeek, building Z (ETEC), room Z103 (1st flooor).

His research group runs highly multi-disciplinary electrochemistry-related research interests spanning renewable energy, materials science and engineering:

“The aim is to understand the properties of new materials for possible development of energy systems and general electrochemical application. In summary, there are three research areas, viz:

  • Energy storage
  • Fuel cells & electrolyzers

We focus on the next-generation batteries (notably Li-S, Na-ion and Li-ion batteries) and electrochemical capacitors (including micro-supercapacitors) which are critical for the ever-advancing consumer electronics, electric vehicles, micro-grids, and for application in extreme environments such as oil & gas, military and space. One of the major challenges that conspire against the performance of electrode materials for modern batteries and electrochemical capacitors is ‘capacity fading’ (i.e., loss of capacity upon repetitive cycling). We are solving this problem by the adoption of a plethora of synthetic strategies aimed at tuning the redox-chemistry and stabilizing the structure of the materials.

Over the years, we have led the study of some new nanostructured electrocatalysts for fuel cell technologies. We are currently exploring the use of microwave-assisted synthesis to develop Pd-based electrocatalysts for fuel cells. Also, we are exploring the use of MN-4 macrocyclic catalysts for both fuel cells and electrolyzers. For example, one of our new projects involves the development of novel MN-4 macrocyclic catalysts for efficient electrocatalytic conversion of CO2 to useful liquid fuels.

  • Electrochemical sensors

With the collaboration of our local and international colleagues, we will be exploring the development electrochemistry-based sensors for resource-limited environments. The aim is for such electrochemical sensors to meet most (if not all) of the WHO’s ASSURED criteria (Affordable, Sensitive, Specific, User-friendly, Robust and rapid, Equipment-free, and Deliverable to those who need them)”.
