| description | Abstract The manipulation of polymeric micelles across extended-length scales is a key challenge in the design of integrated mesoporous materials with well-defined geometry and advanced functions. Herein, we demonstrate a modular assembly strategy to construct metal nanoparticle functionalized mesoporous carbon two-dimensional (2D) nanosheets by organizing zero-dimensional (0D) spherical monomicelle modules on the 2D supporting blocks. The modular assembly process involves two key steps: the “modularization” step is used to synthesize highly uniform metal–catecholamine (MC) complex functionalized monomicelle “modules” that can be conveniently assembled on the 2D supporting blocks (graphene oxide (GO), WS2, and MXene) in the following “assembly” step. After an annealing process, the resultant composites possess a single-layered 2D nanosheet surrounded by two single-layered mesoporous carbon at both sides and exhibit highly ordered mesostructures with large surface areas (~385 m2 g−1), tunable pore sizes (16–25 nm) and highly dispersed metal-containing nanoparticles. Due to the modularity of this assembly process, a range of metal species (Co, Fe, Ni, V, Cu, Pd, FeCo, CoNi, and FeCoNi) can be in-situ incorporated into the 2D mesoporous frameworks, which are partially embedded in the pore walls with the remaining part exposed in the pore channels. Benefiting from the unique textual structures, the resultant GO-derived functional mesoporous carbon nanosheets (Co as the functional species and being annealed at 850 °C) exhibit excellent electrocatalytic activity, long-term stability, and superior methanol tolerance for oxygen reduction reaction, which holds great potential as a catalyst for fuel cells. |
