About Prof Omotayo A Arotiba

Teaching Duties:

Physical chemistry across all the levels in the department

Research Interests:

I am an electrochemist (Physical Chemistry) by training and my core research interest is the use of electrochemistry as a tool to solving problems/challenges in material, biomedical and environmental spheres. These include (but not limited to):

  • electrochemical biosensors and sensors based on dendrimer nanocomposites
  • photoelectrochemical reactors for water treatment
  • electro-synthesis and characterisation of novel materials/compounds in chemical research
  • nano-electrochemistry – synthesis and application of nanomaterial-based electrodes
NRF Rating:

C1
