Title: Low-dimensional Carbon-based Catalyst: Design, Synthesis and Application for the fields of Clean Enengy.
With the enormous depletion of fossil fuels and excessive emission of greenhouse gases, the prominent energy crisis and environmental degradation have increasingly attracted humankind’s attention. Carbon-based materials, as noval catalytic materials with advantages of easy preparation, low cost, high stability, non-toxicity, high hydrophilicity and efficient photoelectron conversion ability, have been widely applied in the fields of clean energy catalysis, such as hydrogen evolution reaction, carbon dioxide reduction and nitrogen fixation. The research on carbon-based catalysts has gradually deepended from high-dimensinal to low-dimensial, which is from 3D bulk porous carbon foam, 2D flake graphene, to 1D carbon nanotubes and quantum-scale carbon dots. As the size decreases, quantized low-dimensional carbon materials, especially carbon quantum dots, provide the huge advantages in specific surface area, richer oxygen-containing groups and more defect sites, which are all considered as an efficient active reaction sites in the energy-catalyzed reaction. In addition, low-dimensional carbon materials will be easier to assemble with other traditional semiconductor catalysts (such as Cu2O, TiO2, etc.) into composite materials with the broad contact interface that can provide efficient electron transport capabilities and outstanding interface synergy. Low-dimensional carbon materials benefiting from quantization could provide huge development prospects for photocatalysis and electrocatalytic clean energy applications due to their excellent electrical conductivity and photogenerated electronics.
