A facile nonpolar organic solution process of a nanostructured hematite photoanode with high efficiency and stability for water splitting

Artur Braun, Yelin Hu

We present a facile nonpolar organic solution synthesis and processing method for water splitting photoanodes based on iron oxide with a relatively low sintering temperature (550 degrees C). The photocurrent of these photoanodes can reach 3.3 mA cm(-2) at ...
