Rituraj Borah

Research Expertise:The broad area of interest is materials and processes related to the current energy and healthcare challenges. Thus, my research activities encompass functional material development for photocatalytic, photoelectrochemical, electrochemical, light harvesting, and sensing applications as well as design of reactor systems/devices for their optimal performance. My research strategy is the combination of fundamental insights gained through theoretical investigations with experimental research. For the fabrication of functional interfaces, the focus is the colloidal synthesis and self-assembly techniques due to their cost effectiveness, sometimes combined with other thin film deposition techniques. For system design, I exploit FEM models of the relevant physics (Maxwell's equations, Navier-Stokes equations, Nernst-Planck equations, and so on). My current focus is the development of scalable photoelectrochemical cells for sustainable hydrogen production, CO2 capture and other (photo)electrochemical processes.
