Abstract

The invention discloses a bifunctional MoS 2 / ZnO composites in the application of bisphenol A trace detection, the MoS 2 / ZnO composites prepared by ①MoS 2 Preparation, ②MoS 2 / ZnO is prepared in two process steps. The method of the invention has simple operation process, low cost and good reproducibility, and the obtained Raman enhanced signal has high sensitivity and good stability, and has important research value and good application in the field of preparing composite materials. Application prospects, and the MoS prepared by this method 2 The / ZnO composite material has a very good photocatalytic effect on MB and can also realize the trace detection of BPA.

Description

technical field [0001] The invention belongs to the field of bifunctional material preparation, and in particular relates to a bifunctional MoS with both photocatalytic and surface-enhanced Raman properties 2 Preparation method of / ZnO composite material. Background technique [0002] Methylene blue is a commonly used dye, widely present in industrial production wastewater, causing serious pollution and damage to the ecological environment, and serious harm to humans and animals, which can cause nausea, abdominal pain, precordial pain, dizziness, headache , sweating and confusion and other adverse reactions. Therefore, the wastewater containing methylene blue dye is a difficult problem faced by the current water treatment technology. [0003] Currently commonly used treatment methods are physical, biological and chemical methods. The physical method is a method of treating insoluble suspended pollutants in the wastewater containing methylene blue by physical action. This ...
