Description

A kind of porous nano NiFe2O4Preparation method
Technical field
The present invention relates to a kind of porous nano NiFe2O4Preparation method, belong to field of photocatalytic material.
Background technology
With the quickening of process of industrialization, energy crisis and environmental crisis getting worse, the exploitation of renewable new energy is standby It is concerned.Solar energy is inexhaustible, nexhaustible, pollution-free, cheap, world community can as a kind of clean energy resource The energy freely utilized peacefully, and various regenerative resources for example biomass energy, wind energy, ocean energy, water can etc. other energy it This.National governments all attach great importance to the exploitation of regenerative resource, and regenerative resource is the hot research field that various countries invest energetically.
Photochemical catalyst is the semi-conducting material of a kind of utilization solar energy indispensability.At present, by scientists study Semiconductor light-catalyst species is various, such as TiO2、CdS、SrTiO3、RuO2, ZnO and Fe2O3Deng.NiFe2O4Partly led as one kind Body photochemical catalyst, has the characteristics that good stability, indissoluble, environmental-friendly, band gap is narrow, aboundresources and application cost are low, especially When being with other semiconductors couplings, photocatalytic activity can be effectively improved, is one of the photochemical catalyst that application prospect is had an optimistic view of.
The structure of material and performance are closely related, structures shape performance, and the controllable preparation of material structure is material science neck The hot research direction in domain, is the important means for preparing high performance material.Grinding on nano material controllable method for preparing at present It is many to study carefully report.Since Penner in 1987 et al. proposes the template synthesis method of nano material, template is because having work Skill is simple and convenient to operate, low power consumption and other advantages, is had received widespread attention.Using template, by varying template diameter and Other technological parameters can obtain the controllable nano material of shapes and sizes.Nanocrystalline, nano thin-film is had been used at present, is partly led The preparation of the materials such as body, nanotube and nano wire, has consequence in field of nano material preparation, becomes preparation high-performance The important means of nano material.
NiFe2O4Nanosizing and porous are to improve NiFe2O4One of effective ways of photocatalysis efficiency.Prepare porous receive Rice NiFe2O4Can use template, template mainly have microemulsion template, emulsion template, ionic surfactant template, it is non-from Subtype surfactant templates, block copolymer template, composition template (such as polyoxyethylene lauryl ether and polyethylene glycol) With monodisperse polymer particles template etc..Pass through solgel reaction, NiFe2O4Colloidal sol forms bone with secondary bond and template action Frame structure, then takes solvent extraction or high-temperature roasting method to remove template, so as to obtain the hole suitable with template size.But It is to prepare porous nano NiFe using above-mentioned traditional template2O4When, template is either removed using roasting method or extraction All there are major defect.When roasting method removes template, since the temperature of template to be eliminated is high, caving in for duct can be caused, makes system Into porous nano NiFe2O4Semiconductor light-catalyst surface defect is too many, becomes the complex centre of electron-hole, reduces light and urges Change efficiency.Extraction rule is difficult to thoroughly eliminate template so that porous nano NiFe2O4The purity of semiconductor light-catalyst reduces, and leads Photocatalysis performance is caused to decline.Therefore, how to prepare duct without cave in, surface zero defect, template noresidue and high-specific surface area Porous nano NiFe2O4Semiconductor light-catalyst is an important topic.
Easily removed since sublimate easily distils, the present invention is by using the appropriate compound of sublimation temperature Template prepares NiFe2O4Colloidal sol, reheating make template distillation removing can be prepared by porous nano NiFe2O4.With traditional template Compare, the present invention use sublimate for template can preparation structure is controllable, duct without cave in, surface zero defect, template noresidue and The big porous nano NiFe of specific surface area2O4Semiconductor light-catalyst.At present, on being prepared by template of sublimable compound Porous nano NiFe2O4The method of semiconductor light-catalyst is there is not yet document report, is porous nano NiFe2O4Preparation open up One new way, has an important practical significance.
The content of the invention
A kind of porous nano NiFe of the present invention2O4Preparation method, there is provided it is a kind of with molysite, nickel salt, alkali, go from Sub- water is raw material, and NiFe is prepared by stirring reaction2O4Colloidal sol;NiFe2O4Colloidal sol is after ultrasonic disperse, by certain ratio Example adds organic solvent and sublimable compound template, and after the hot method reaction of water-organic solvent mixed solvent, product is through steaming Distillation removes mixed solvent, heats removing sublimable compound template, cooling, washing, drying and grinding technics process, i.e., Obtain porous nano NiFe2O4
A kind of porous nano NiFe of the present invention2O4Preparation method, obtained porous nano NiFe2O4, can Light and sunlight are seen under conditions of light source, to can be directly used for photocatalysis degradation organic contaminant and photocatalytic hydrogen production by water decomposition, Also the photochemical catalyst of active higher by the method with other semiconductors couplings, can further be made, in visible ray and sunlight Under conditions of light source, for photocatalysis degradation organic contaminant and photocatalytic hydrogen production by water decomposition;
