Personal profile

Research interests

Frank Marken has in September 2004 been appointed to a Senior Lecturer position at the University of Bath and promoted to Reader in 2008 and to Professor in 2011. General research interests are linked to water, solar energy, and sensing. This includes the development of novel electrochemical technologies including oxide nano-structure electro-catalysis for CO2 reduction, liquid-liquid triple phase junction processes, bio-electrochemical processes, ultrasound and microwave and sunlight-enhanced electrochemistry, solid state electrochemical processing, iontronics and ionic diodes in desalination, paired and self-supported organic syntheses, and industrially relevant electrode reactions (more than 480 publications). In 2009 Frank Marken was awarded the Theophilus Redwood lectureship by the Analytical Division of the RSC and in 2018 he was awarded the RSC Geoffrey Barker medal.


Electrochemical reactions occur when charges move across interfaces (e.g. electrode | liquid or liquid | liquid interfaces or more complicated interfacial structures). The potential applied to the electrode and the material and interfacial design allow processes to be controlled or selected. I am interested in both fundamental and applied aspects of electrochemistry linked to water and to energy and in particular in (i) how energy (light, microwave, ultrasound, etc.) can be used to beneficially modify (or couple into) interfacial processes, (ii) triple-junction processes (electro-insertion, emulsion processes, gas-diffusion cells for CO2), novel electrode designs and materials (e.g. diamond, junctions, and nanoparticle assemblies, polymers of intrinsic microporosity), (iii) catalytic processes, (iv) bioelectrochemical processes, and (v) transport processes at interfaces on micro- and macroscopic level.
