Guillermo Díaz-Sainz received his Degree in Chemical Engineering (2015) from the University of Cantabria and his MSc. in Chemical Engineering (2017) delivered from the University of Cantabria (UC) and the University of the Basque Country. In 2021, he completed his Ph.D. in Chemical Engineering, Energy and Processes focused on the development of processes for CO2 electrocatalytic reduction to formate. He is currently integrated into the Research Group DePRO (Development of Chemical Processes and Pollution Control), and at present, he is Assistant Professor in the Chemical and Biomolecular Engineering Department. Currently, the research activity and mid/long term interests of Dr. Diaz-Sainz are mainly focused on the development of an innovative process for the CO2 capture and photo/electrochemical conversion in products of interest, and at the same time, the production of green hydrogen by electrolyzers.
