A physical and chemical experiment was designed to prepare silicon doped carbon quantum dots and detect mercury ions in aqueous solutions.Silicon carbon quantum dots(Si-CQDs)were synthesized by one-step microwave heating of the mixture of 3-aminopropyl trimethoxysilane(APTMS)and sulfuric acid(H_(2)SO_(4))to prepare silicon carbon quantum dot colloid.A series of characterization was performed to researching the physical and chemical properties of silicon carbon quantum dots.Finally,the specific applications of silicon carbon quantum dot colloids were introduced through mercury ion detection experiments.The implementation of this experiment integrates frontier scientific research achievements into the teaching of physical chemistry experiments,which helps to stimulate students'interest in learning and improve their awareness of environmental protection.
