Problems solved by technology

[0003] In recent years, in order to realize the preparation of high-performance materials and the verification of computer simulation optimization results, there are many methods for preparing arrays, such as template method, corrosion method, etc., but many methods are too complicated and not suitable for industrial applications, and our The invented carbon black template method has a wide range of applications and materials, and is easy to control the appearance and size. The equipment is extremely simple and is suitable for industrial applications of high-performance materials.
[0004] So far, no method has been found to use carbon black to make nanoscale templates

Abstract

The invention relates to a preparation method for carbon black, specifically to a preparation method for a size-controllable amorphous carbon array. According to the invention, the characteristic that carbon black is simple and easy to prepare is utilized, and carbon black is very uniform and fine (40 nm) and is allowed to enter a template material to prepare a carbon black array; and the characteristics of a magnet switch are skillfully utilized, so the prepared array is not destroyed. The size-controllable amorphous carbon array prepared in the invention can be applied to the fields of gas-solid reactions, computer-simulated calculation and verification, etc.; and the array is simple and easy to operate.

Description

technical field [0001] The invention relates to a method for preparing carbon black, in particular to a method for preparing a size-controllable amorphous carbon array. Background technique [0002] Catalytic reactions require very high contact between reactants and catalysts, especially gas phase reactions. Exhaust gas treatment of automobiles and other exhaust pipes has higher requirements for this. The gas phase must be in full contact with the catalyst, expose more active sites, and make the products detach quickly, thereby increasing the reaction rate. In addition, the wide application of computer simulations can already optimize the appropriate size, but experimental verification is required. It is very difficult to prepare a micron array of a specific size or the technology is extremely complicated, and many optimization results cannot be actually verified. Therefore, finding and optimizing the size of the pore size of the material is a key technical issue to make a ...
