The goal of this group is to make hydrogen/carbon-based fuels by utilizing solar energy and H2O/CO2. This technology is considered a promising approach to reducing CO2 emissions and achieving the goal of carbon neutrality.
The photocatalytic reaction
is driven by solar energy directly.
PV-EC reactions involve two parts: one is converting solar energy into electricity through a photovoltaic (PV) module, and the other is using this photogenerated electricity to drive an electrocatalytic cell producing fuels.
A typical PEC cell consists of (photo)cathode,
(photo)anode, and a supporting electrolyte. The HER and CO2R happen on the (photo)cathode side, while the OER happens on the (photo)anode side.
