« Electrochemistry in sensing and water treatment: exploiting nanomaterials and semiconductors »
Health and water are global challenges and thus part of the Sustainable Development Goals 3 and 6 respectively. Simple and low-cost diagnostic sensing tools are important in health, food and environmental monitoring. Furthermore, sustainable and more robust complementary and/or alternative water treatment methods are needed to meet the challenges of providing usable water from polluted water or wastewater. The application of electrochemistry to meeting these challenges cannot be overemphasised. Electrochemistry is a core science behind technologies such as sensors, biosensors, fuel cell, solar cell, water splitting, hydrogen generation, non-conventional water treatment and other low cost/sustainable industrial methods. In this seminar, I present an overview of my research contribution in electrochemistry for sensors and water treatment. I will place emphasis on the use of nanomaterials such as dendrimer in sensor design and the use of semiconductors in the design of photoelectrocatalytic (PEC) systems for the removal of organics pollutants from water. I will share my research progression in materials electrochemistry with semiconductors and heterojunctions especially for water treatment. I look forward to meeting you all for an interesting discussion and contributions towards solving our global challenges together.
