Application of 1D/2D carbon material supported metal nanoclusters for electrochemical conversion

“…76 Next, the strong interaction between the metal and GDY results in a uniform distribution of the metal and prevents aggregation, which contributes to the long-term stability of the electrocatalytic reaction. 77–79 Finally, the presence of two acetylene bonds in GDY leads to doubling of the length of the carbon chain connecting the six-membered ring, 80–82 and this large pore formed by six acetylene bonds is very favorable for the loading of metal nanoclusters. 83…”

Theoretical Computation for In-Depth Insights into Structure, Properties, and Energy-Storage/Conversion Application of Graphdiyne

“…With the challenge of the global energy crisis, energy storage devices are becoming an important part of daily life, which makes energy storage materials and catalysts the focus of research. Carbon materials have been widely studied as excellent energy field materials in the past decade. − As an allotrope of carbon, GDY has a unique porous structure and excellent electronic properties, making it particularly suitable for energy applications. However, due to the limitations of its experimental synthesis, there is still a gap between the ideal GDY structure and the actual one, which makes it difficult to carry out an in-depth theoretical study on it.…”

Heteroatom Modified TiO2/Graphene Aerogel Composites by Electron Beam Irradiation in Supercapacitors

“…The supercapacitor, as one of the frontier technologies in the energy field, with ultrahigh energy density, ultralong cycle life, and ultrafast charge/discharge rates, can meet the urgent needs of energy storage devices and is a hot research topic currently. − Carbon-based materials play a very important role in the design of electrode materials for supercapacitors due to their good electrical conductivity, excellent stability, and large surface area. , Among them, graphene has attracted a lot of attention as a carbon material with excellent mechanical, chemical and thermal properties, and a theoretical capacitance of up to 520 F g –1 . − However, due to the strong π–π interaction and van der Waals interaction, graphene sheets undergo stacking, resulting in a decrease in specific surface area and low electrical conductivity, which limits their practical application in energy storage. , …”

“…Currently, heteroatom doping (N, S, P, B, etc.) produces a certain pseudocapacitive behavior and is proven to be an effective way to further improve the capacitive properties of the material. , For example, Sharavath et al, synthesized N-doped TiO 2 /graphene nanocomposites (N-TiO 2 /NG) by hydrothermal method and achieved a specific capacitance of 205.1 F g –1 at 1 mV s –1 and cycling stability of 78.8% after 5000 consecutive charges and discharges at 1 A g –1 , which have more excellent electrochemical properties. In addition, the codoping of two or more elements with different electronegativity (e.g., N, S) causes unique electron distribution and induces structural distortions, resulting in a synergistic effect that can more effectively improve the electrochemical properties of the material. ,, So far, many methods have been used to prepare N, S codoped carbon materials (e.g., hydrothermal/solvothermal reaction, high-temperature calcination, etc.…”
