Title: | Chemical solution synthesis of copper-based photocathode materials towards photoelectrochemical reduction of CO2 | Authors: | DEBUSSCHERE, Nele JOOS, Bjorn ELEN, Ken VAN BAEL, Marlies COOL, Pegie HARDY, An |
Issue Date: | 2022 | Source: | CRF-ChemCys, Blankenberge, België, 12/10/2022-14/10/2022 | Abstract: | Recently, there has been an interest in photoelectrochemical (PEC) conversion of CO 2 into fuels and chemical building blocks. To design such a system, we need appropriate semiconducting photoelectrodes. PEC limitations 1 : • Limited light absorption • Charge separation and transport • Photocorrosion • Selectivity Aqueous Cu precursor Conclusion: CuFe 2 O 4 confirmed with Raman and XRD Outlook: Material ready for CO 2 reduction tests Multi-metal precursor Bandgap 2 : 1.4 eV Natural p-type Photochemical stability Low onset potential Bandgap 3 : 1.5 eV Natural p-type High stability High conductivity High photovoltage possible for CO 2 reduction Conclusion: CuFeO 2 confirmed with Raman and XRD Outlook: Material ready for CO 2 reduction tests Aqueous Cu precursor Aqueous Fe precursor Multi-metal precursor Gel Multi-metal precursor CuFe 2 O 4 powder | Document URI: | http://hdl.handle.net/1942/39511 | Category: | C2 | Type: | Conference Material |
