Abstract

This patent proposes a kind of brand-new Ag/Cu based on redox reaction2The liquid phase reactor preparation method of O composites.Its component and compositional system can be regulated and controled by thermodynamics and material ratio.The Ag/Cu prepared based on such a method2O composites have potential application in terms of photocatalysis and fax sense.

Description

A kind of brand-new Ag/Cu based on cell reaction2O composite material and preparation method thereofs
Technical field
The invention belongs to preparing technical field.From AgNO3Set out, based on cell reaction principle, lead to for raw material with Cu Cross to thermodynamic (al) control, so as to Ag/Cu2The preparation and regulation and control of O composites provide a kind of brand-new technological process.At present The compound has good anti-microbial property and light-catalysed performance,
Background technology
Semi-conducting material wide application, there is more research and development potential quality at present.The composite mixed of semi-conducting material is still to carry The conventional method of high material property.Current synthesis technique is also a lot, but new synthesizing mean, the research of synthetic technology route Also the basic research for the smooth application for exploring high performance composite is turned into.This method is set using the method based on cell reaction The synthesis of composite is counted, is synthesized in the way of one-step synthesis, this simple highway route design and the technique stream simplified Journey can provide solid theoretical research foundation for the application of composite.
The content of the invention
It is an object of the invention to provide a kind of new synthesis Ag/Cu2The preparation method of one synthesis of O composites.
The present invention is achieved by the following technical programs：Pass through thermal chemical reaction AgNO3+ Cu=Ag+Cu2O design stock and The synthesis of material, the Ag/Cu of different proportion composition is synthesized by the silver nitrate and copper needed for addition2O composites, Shown in following example：
Example one：AgNO3Powder is dissolved in distilled water, is placed in constant temperature blender with magnetic force, adds PVP, is stirred at 5min, 60 DEG C NaOH stirrings are added, 60 DEG C of 5 hours of stirring of addition Cu powder continuation obtain product, centrifuge, wash drying, finished product.
Example two：AgNO3Powder is dissolved in distilled water, is placed in constant temperature blender with magnetic force, 70 DEG C of stirring 5min, adds NaOH 3min is stirred, PVP is added, 5min is stirred for, 70 DEG C of 3 hours of stirring of addition Cu powder continuation obtain product, centrifuged, washing is done It is dry, finished product.
Example three：AgNO3Powder is dissolved in distilled water, is placed in constant temperature blender with magnetic force, adds PVP, is stirred at 5min, 80 DEG C NaOH stirrings are added, 80 DEG C of 3 hours of stirring of addition Cu powder continuation obtain product centrifugation, wash drying, finished product.
Example four：AgNO3Powder is dissolved in distilled water, is placed in constant temperature blender with magnetic force, adds PVP, is stirred at 5min, 70 DEG C NaOH stirrings are added, 70 DEG C of 2 hours of stirring of addition Cu powder continuation obtain product centrifugation, wash drying, finished product.
Example five：AgNO3Powder is dissolved in distilled water, is placed in constant temperature blender with magnetic force, adds PVP, is stirred at 5min, 75 DEG C NaOH stirrings are added, 75 DEG C of 2.5 hours of stirring of addition Cu powder continuation obtain product centrifugation, wash drying, finished product.
Example six：AgNO3Powder is dissolved in distilled water, is placed in constant temperature blender with magnetic force, adds PVP, is stirred at 5min, 65 DEG C NaOH stirrings are added, 65 DEG C of 3.5 hours of stirring of addition Cu powder continuation obtain product centrifugation, wash drying, finished product.
