Here we presented a new facile strategy to fabricate ultrathin two-dimensional (2D) metal oxide nanosheets, by using polydopamine-coated graphene (rGO@PDA) as a template under simply wet-chemical conditions. Based on the strategy, graphene-like CeO-TiO mesoporous nanosheet (MNS-CeO-TiO) was prepared and was loaded with dispersive Ag nanoparticles (AgNPs) to obtain effective electrocatalysts (denoted as Ag/MNS-CeO-TiO) for electrochemical detection of superoxide anion (O). Characterizations demonstrated that MNS-CeO-TiO exhibited ultrathin thickness, larger specific surface area, and pore volume in comparison with its bulk counterpart. Read More
