Three-Dimensional Macroscopic Assemblies of Low-Dimensional Carbon Nitrides for Enhanced Hydrogen Evolution

摘要

Nanomaterials feature unique surface, optical, and electronic properties that are often superior to their bulk counterparts. These properties are often interpreted as surface effect and dimensional confinement, which forms the basis to design the nanoscale building blocks or devices for catalysis, electronics, or optics.As these properties are primarily determined by crystallinity, shape, and size of the material, great research efforts have been devoted to the synthesis of nanostructures with well-defined composition and morphology. To date, metals, metal oxides, metal chalcogenides, and organic materials based on molecules and macromolecules have been reported in the form of various nanostructures, ranging from zero-dimensional (0D) nanoparticles, through one-dimensional (1D) nanowires and nanotubes to two-dimensional (2D) nanosheets.
