Product Features

1. Structural characteristics: It has two hybrid states, sp and sp2, as well as rich carbon chemical bonds, large conjugated systems, wide interplanar spacing, and excellent chemical stability.  
2. Physical properties: The interlayer spacing of graphene acetylene is 0.365 nanometers. Theoretically, as the thickness of graphene acetylene decreases, its conductivity gradually increases.  
3. Chemical properties: Graphene acetylene has excellent semiconductor properties, similar to those of silicon, and its unique molecular and electronic structure not only has electron donating properties, but also electron withdrawing properties.

Application of High Purity Graphdiyne Powder:

1. In the field of electronics and semiconductors, graphitic alkynes are expected to be widely used due to their unique electronic structure and excellent semiconductor properties. For example, doping graphene acetylene into the electron transport layer of hybrid perovskite devices can effectively improve the conductivity of the electron transport layer, thereby enhancing the device performance of perovskite cells.  

2. Energy field: Graphene acetylene is an ideal lithium storage material, and its unique structure is more conducive to the diffusion and transport of lithium ions both in-plane and out of plane, endowing it with excellent rate performance. The theoretical capacity of lithium storage in graphite acetylene reaches 744mAh/g, and the theoretical capacity of multi-layer graphite acetylene can reach 1117mAh/g (1589mAh/cm ³). In addition, graphitic acetylene can also be used as an efficient positive electrode material for potassium sulfur (K-S) batteries, improving battery performance.  

3. In the field of catalysis, graphitic acetylene has excellent catalytic performance, such as the efficient catalytic reduction of 4-nitrophenol by loaded metal palladium, with a much higher reduction rate than other carbon based Pd composite nanomaterials. Meanwhile, graphitic acetylene can also serve as a supporting substrate to regulate the catalytic performance of electrochemiluminescence (ECL).  

4. In the field of optoelectronics, perovskite solar cells constructed by combining graphene acetylene and P3HT as modified materials can significantly improve hole transport performance. Based on this composite hole transport layer, the photovoltaic conversion efficiency of perovskite cells has increased by 20%, achieving a high efficiency of 14.58%.  

5. Other fields: Graphene acetylene can also be used to filter out sodium chloride in seawater and as a buffer layer for quantum dot batteries.

Storage conditions:

High Purity Graphdiyne Powder should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time, to prevent agglomeration due to moisture, affecting the dispersion performance and use effect, and should avoid heavy pressure, do not contact with oxidant, and transport according to ordinary goods. Expiry date: Half a year.
