The Cover Feature shows the photoelectrochemical activation of C−H bonds with mesoporous SnO2 electrodes sensitized with a quinacridone dye (pigment violet 19, used in paints). The key feature of quinacridone is the possibility to operate through a proton‐coupled electron transfer mechanism, generat...
