Figures of Merit for Photocatalysis: Comparison of NiO/La-NaTaO<sub>3</sub> and <i>Synechocystis</i> sp. PCC 6803 as a Semiconductor and a Bio-Photocatalyst for Water Splitting

While photocatalysis is considered a promising sustainable technology in the field of heterogeneous catalysis as well as biocatalysis, figures of merit (FOM) for comparing catalytic performance, especially between disciplines, are not well established. Here, photocatalytic water splitting was conduc...
