FeS_𝟐-Quantum-Dot Sensitized Metal Oxide Photoelectrodes: Photoelectrochemistry and Photoinduced Absorption Spectroscopy

Figure 4

IPCE spectra of FeS₂ modified TiO₂-np (filled triangle), ZnO-nr (filled square), and ZnO-np (filled circle). Inset is a band gap determination from square root of IPCE spectra of FeS₂-modified metal oxide electrodes: (a) ZnO-np, (b) TiO₂-np, and (c) ZnO-nr electrodes.
