Über die Stabilität von Anoden(photo-)elektrokatalysatoren in der Solar zu Wasserstoff Verbindung

Autor: Knöppel, Julius

The sustainable production of hydrogen for energy storage and utilization is an important cornerstone to overcome global warming, one of the biggest challenges of our time. One method to produce hydrogen is (photo-)electrochemical water splitting. It

Photocorrosion of WO 3 Photoanodes in Different Electrolytes

Autor: Knöppel, Julius, Kormányos, Attila, Mayerhöfer, Britta, Hofer, André, Bierling, Markus, Bachmann, Julien, Thiele, Simon, Cherevko, Serhiy

Publikováno v: ACS physical chemistry Au 1(1), 6-13 (2021). doi:10.1021/acsphyschemau.1c00004

Photocorrosion of an n-type semiconductor is anticipated to be unfavorable if its decomposition potential is situated below its valence band-edge position. Tungsten trioxide (WO3) is generally considered as a stable photoanode for different photoelec
