• the poor separation efficiency and migration ability of the photo-excited charge carriers. A variety of effects have been made to enhance the photocatalytic performance of ZnIn2S4. For example, by size control on ZnIn2S4 [20], doping with transition metals [21] and incorporation of metal sulfides [22

• distributions of the final Au NP. Experimentally, a size window of 2 nm ≤ diameter ≤ 12 nm for Au NP can be realized if the monomer number especially of the P2VP block is properly adjusted [6]. Thus, size control as required in 1) above is principally given by the micellar approach. In practice, however, with
