The goal of the PolyHER project is to design a new type of electrode from porous conductive polymers (CPs) coated with low-cost electrocatalytic material based on transition metal dichalcogenides (TMDC). By varying synthesis parameters, one will maximize the catalytically active site's concentration. Catalytic activity will improve additionally by milling of TMDC with additives. This way, both the conductivity and active surface of the material will increase. To get the electrode, the catalyst will be deposited on the porous conductive polymer carrier. This composite electrode will have attractive mechanical properties and processing advantages of polymers, but also good conductivity. Additionally, porous conductive polymers integrate the properties of the material itself and the benefits of its porous structure. To build up a functional, cheap electrode for HER, superior to the currently available ones, we will carry out a detailed electrochemical analysis, examine possible improvements by varying the electrode design and load of the catalyst, and study its long-term stability.
