The Inside Back Cover image shows the photo‐oxidation of water using silver phosphate/carbon nitride (Ag 3 PO 4 /g‐C 3 N 4 ). While tremendous efforts into the development photocatalytically active materials afforded highly efficient H 2 evolution catalysts, the complementary, water oxidation reaction (mechanistically more demanding) remains the major obstacle for overall water splitting. The composite material is superior in both efficiency and stability compared to pristine Ag 3 PO 4 and C 3 N 4 . A detailed analysis of the reactions mechanism strongly implies the in situ formation of an effective Z‐scheme (mimicking photosynthesis in nature) through formation of Ag nanoparticles at the material interface under illumination, which is different to the conventional charge transport through the interface; this opens a method for the preparation of catalysts for full water splitting systems and other uphill energy conversion reactions. More details can be found in the Full Paper by Yang et al. on page 1350 (DOI: 10.1002/cssc.201403168 ).
