The sun is a renewable and clean natural resource. Harvesting its energy offers a sustainable alternative to the current fossil fuel-based society for powering many industrial and consumer sectors. Photoelectrochemical (PEC) water splitting is an emerging field for directly storing solar energy in chemical bonds. Semiconductor materials acting as light absorbers must meet a vast number of requirements (bandgap, band edge position, charge transfer kinetics, earth abundance, low cost, …) to efficiently convert water into hydrogen and oxygen especially on a large scale. Although extensive research is conducted world-wide, there is yet a material to be discovered that satisfies all of the stringent conditions. In this light, high-throughput (HT) methods in synthesis and characterization present a promising route to accelerate material discovery in this field.
My research is centered around the automated synthesis of photoelectrocatalyst libraries suitable for solar fuel applications coupled with stability measurements under photoelectrochemical operation. Here, a scanning flow cell (SFC) coupled to an inductively coupled plasma mass spectrometer (ICP-MS) aides in the detection of dissolution products during irradiation and electrochemical experiments. This can help unravel degradation mechanisms occurring under real-world conditions.
