Each batch of nanoparticles is extensively characterized using techniques including SEM or TEM, XRD, COA, etc. In addition to ensuring that every batch of nanoparticles meets our stringent quality control requirements, customers are provided with batch-specific specification sheets containing representative SEM/TEM images,Coatings,dispersions, and solution pH. Nano Graphene Powder, Colloidal Gold Liquid , Hydrophobic Silicon Dioxide Nanoparticles , 20-30nm Iron Oxide Nanoparticles ,70nm Tin Nanoparticles . Nano-material can provide a huge ratio of the surface area, increase the molecular adsorption of the liquid interface, thereby greatly accelerating the speed of electrochemical or photoelectric chemistry; second, the width of the micro-regulation of nano-semiconductor materials can greatly increase the light of solar cell light, which Absorption efficiency. In addition, the nano -porous structure can help electronics and ions to transfer and diffuse inside the material, thereby ensuring the incidence of efficient electrochemical and photoelectric chemical reactions. It is precisely because of these special properties of nanomaterials that it is widely used in the field of new energy materials, such as solar cells, photoelectric catalysis, lithium -ion batteries, hydrogen storage materials, etc. The superior catalytic performance of nanomaterials also makes it many applications in terms of car tail gas treatment and sewage treatment.
