Recent advances on photoelectrochemical water splitting

DESCRIPTION:

The combustion of fossil fuels has significantly contributed to environmental pollution and a substantial increase in atmospheric CO2 and other greenhouse gases. This phenomenon has played a major role on escalating global warming and climate change, adversely impacting on ecosystems worldwide. In this sense, one of the primary objectives of the European Union is to convert solar energy into added-value chemicals and fuels, aiming at reducing imported fossil fuels and minimizing greenhouse gas emissions. Artificial photosynthesis by photoelectrochemical water splitting stands out as one of the most promising approaches. Oxygen evolution takes place at the anode, to provide the protons and electrons for the complementary cathodic reaction (e.g.: hydrogen evolution, CO2 reduction, or nitrogen reduction). However, there are several issues, related to conversion efficiency, stability and scalability, which limit large-scale technological deployment of this technology.

Efforts to overcome such limitations include the design of novel materials and devices, as well as understanding carrier dynamics in the system. In this webinar, we will discuss the recent advances on photoelectrochemical water splitting from these three different perspectives: novel materials, mechanistic analysis and device design and scalability. This will include invited speakers from different European projects (OHPERA, SUN2CHEM, SUNGATE, SOLAR2CHEM, FLOWPHOTOCHEM and A-LEAF). The speakers will have 20 min presentation, followed by 5 min of questions. The webinar will culminate with the forum “Perspectives on photoelectrochemical production of solar fuels” moderated by Prof. Sixto Gimenez, dedicated to exploring the most promising strategies and future outlook in this field.
