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

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 1.23 V vs. RHE with high IPCE and stability, which makes them highly attractive candidate photoanodes for hydrogen generation.
