Best Practices for Assessing Performance of Photocatalytic Water Splitting Systems

Photocatalytic water splitting has become a very popular research subject in recent years. Consequently, it is important to report appropriately standardized experimental data, so that each researcher can properly understand the results generated by others. However, experimental methods and measures of photocatalytic performance are not yet sufficiently systematic. In the present manuscript, experimental procedures and standardization of photocatalytic performance are described in relation to the basic theory of photocatalytic water splitting.
