Technical Field

Background
How to effectively regulate, explain, design and apply chemical reactions so that the reactions are most rapidly and maximally converted and carried out in the direction of human needs has been the goal of green chemistry. The processing characteristics of electric fields, photocatalysis and the like which are commonly used physical processing means show high adaptation phenomena in the aspect of chemical synthesis and strengthening.
