Dr Opoku Francis received his BSc and MPhil degrees from the Kwame Nkrumah University of Science and Technology (KNUST) in 2010 and 2014, respectively. Dr Opoku obtained his PhD in Chemistry from the University of Johannesburg (UJ) in 2019. Prior to his appointment at Kwame Nkrumah University of Science and Technology, Dr Opoku was a Postdoctoral Fellow at the University of Johannesburg for adsorption of small molecules research.

He has served as a continuous reviewer of prestigious science journals, namely; New Journal of Chemistry and Physical Chemistry Chemical Physics (which publishes under Royal Society of Chemistry), and the International Journal of Environmental Analytical Chemistry (published by Taylor & Francis Ltd).

Dr Opoku Francis has devoted his research to the computational simulations, synthesis, characterization, functionalization and advanced applications of semiconductor nanomaterials in energy, environmental monitoring and assessment, including two-dimensional electronic devices, energy conversion and storage devices, photodegradation of organic pollutants, gas sensors, optoelectronic devices, thermoelectric, photovoltaic cell, environmental monitoring and contamination assessment. The high quality of his research papers is evidenced by the high number of citations he has received from other researchers (total citation = 2281; h-index = 23; i10-index = 46). https://scholar.google.com/citations?user=dDxltY8AAAAJ&hl =en. I am working on collaborative projects with the Department of Chemical Sciences, University of Johannesburg (Dr Tunde Lewis Yusuf); Institute for Nanotechnology and Water Sustainability, College of Science, Engineering and Technology, University of South Africa (Dr Potlako John Mafa); University of Electronic Science and Technology, China (Prof Hassan Karimi-Maleh) and a German collaborator from Technische Universität Berlin (Dr Mirabbos Hojamberdiev). I have co-supervised three master students.
