Room temperature hydrogen sensors based on polycarbazole and its derivatives - HYDROSENS

Project summary

The main objective and innovation of the HydroSens project is the exploration of the use of conjugated polymers based on carbazole-derived repeat units as selective receptor layers for hydrogen sensors. In particular, the ability of the sensors to operate at room temperature makes them an energy-efficient and safe (no risk of H2 ignition from the sensor) sensing solution. The HydroSens devices do not require costly high-purity materials or high-temperature processing, instead employing solution-processing methods for the deposition of receptor layers. The results of the project are expected to help minimise greenhouse gas emissions both directly (reduced energy consumption) and indirectly, by promoting the development of an increasingly safe “hydrogen industry”, contributing to a transition from a carbon-based economy to one based on clean and sustainable fuels and energy, such as hydrogen fuel cells.
