SEM images of ZnO nanowire networks with and without a TiO2 protection layer after photoelectrochemical experiments. (a) After one hour of reaction, the nanowires decay and recrystallization of ZnO occurs. (b) After three hours of photocorrosion, the network coated with TiO2 shows no or only small corrosion effects. From L. Movsesyan et al., ©Nanomaterials 8, 693 (2018)
