A scientific workshop of the TELEGRAM project has been held at the fall meeting of the European Materials Research Society (E-MRS) in Warsaw, Poland, from 18 to 21 September 2023. We showed our research within the symposium B titled “Advanced catalytic materials for (photo)electrochemical energy conversion IV”. In addition, we presented a poster to address the widest possible audience and give an anchor point for further discussions. The workshop has given the opportunity to present the whole project in a cohesive way, drawing the attention of the scientific community to the multifaceted approach we have taken to address the topic.
