Synthesis of Carbon Quantum Dots The synthesis of carbon quantum dots can be mainly divided into two categories: top-down method and bottom-up method. Through the pre-treatment, preparation, and subsequent processing, carbon quantum dots can be controlled in size, passivated on the surface, doped with heteroatoms, and nanocomposites to meet the requirements. Top-down approach Top down method: lase...

The specific surface area of a powder is an important physical property, which refers to the total surface area (in square meters) of an oxide powder per unit mass (in grams). The size of the specific surface area is related to factors such as particle size, shape, and porosity of the powder. Generally speaking, the smaller the particles and the higher the porosity, the larger the specific surface...
