The present invention relates to a kind of synthetic method of cobalt disulfide nanobelt package assembly in titanium sheet substrate, the steps such as the preparation including cobalt disulfide nanobelt in the preparation of cobaltosic oxide nano band in the synthesis of cobalt hydroxide nanobelt in titanium substrate, titanium substrate, titanium substrate, prepare cobalt disulfide nanobelt package assembly in titanium sheet substrate.Compared with prior art, simple and easy to apply, reproducible, obtained cobalt disulfide nanobelt novel in shape of the invention, is evenly distributed on titanium-based basal surface, Stability Analysis of Structures, and with titanium substrate rigid contact, be conducive to electric transmission and interfacial reaction.This product can be widely used in electro-catalysis field directly as two-dimensional electrode material, with excellent electrolysis water H2-producing capacity.
Description
Technical field
The present invention relates to a kind of synthetic method for producing hydrogen catalyst, received more particularly, to cobalt disulfide in a kind of titanium sheet substrate
Synthetic method of the rice with package assembly.
Background technology
Hydrogen energy source is as a kind of emerging regenerative resource, and its development technique is along with the research and development of production hydrogen catalyst material
Continue to develop.Therefore develop with efficient catalytic performance, cost be low, free of contamination production hydrogen electrode material, have become hydrogen energy source
The focus in field.Nano-electrode material has larger specific surface area and surface-active due to it, and hydrogen field exhibition is produced in electro-catalysis
Good electrochemical applications value is revealed.At present, platinum-group noble metals material is known most efficient electro-catalysis production hydrogen material,
But it is due to that its reserves is limited, cost is too high, causes its application to be restricted, therefore develop base metal production hydrogen and urges
Agent, as metal sulfide, metal selenide, metal carbides etc. are cheap, easily made from new material, be just increasingly subject to
The extensive concern of people.
In electrolysis aquatic products hydrogen system, the main function that production hydrogen catalyst is played is the change for reducing free energy in course of reaction
Dynamic amplitude, so that evolving hydrogen reaction can be carried out smoothly descent.In the first row transition metal double sulfide (FeS2、CoS2、
NiS2) in molecular structure, metallic atom is connected with the sulphur atom of surrounding with octahedral form, this structure with biosystem
Liberation of hydrogen catalyst hydrogenase avtive spot it is similar, it is particularly conductive with metalloid therefore with the performance of catalysis production hydrogen
Property cobalt disulfide, show excellent catalytic activity in electrolysis aquatic products hydrogen field.At present, the growth in situ in conductive substrates
Two dimension or three-diemsnional electrode material, the features such as being in close contact due to it without the fixation of adhesive, electrode material and substrate, from
And the advantages such as transmission are more easy to easy to operate, electronics, it is increasingly becoming the study hotspot of production hydrogen electrode material.
The pattern of cobalt disulfide is grown in conductive substrates includes nano wire, nanometer sheet, pyrometric cone etc., but is due to pure phase
The catalysis H2-producing capacity of cobalt disulfide can not have further lifting, therefore most work depend on and cobalt disulfide is doped
Or synthesis bimetallic sulfide composite, cause that the flow for preparing material is cumbersome, controllability is not strong, product heterogeneity.
Based on above mentioned problem, we have developed a kind of synthetic method of the package assembly cobalt disulfide nanobelt using titanium sheet as substrate, production
Product novel in shape, Stability Analysis of Structures, yield is high and is evenly distributed, and easy to operate controllable, H2-producing capacity has a certain degree of lifting,
And better than the catalytic performance for the non-package assembly cobalt disulfide nanobelt being transformed by solution phase precursor, it is expected to extensive use
In fields such as ultracapacitor, lithium ion battery, full electrolysis aquatic products hydrogen production oxygen.
Chinese patent CN104402065B discloses the preparation method of spherical cobalt disulfide nano-powder, will be analytically pure
CoCl2·6H2O, which is added in deionized water, obtains solution A;Analytically pure thiocarbamide SC (NH are added into solution A2)2, obtain molten
Liquid B;Watery hydrochloric acid is added into solution B or sodium hydroxide solution regulation pH obtains solution C.The solution C of above-mentioned preparation is poured into hydro-thermal
In reactor, reactor is then sealed, reactor is put into warm-pressing double-control microwave oven, selection temperature control mode carries out hydro-thermal
Reaction, is then respectively adopted watery hydrochloric acid, and carbon disulfide, deionized water, absolute ethyl alcohol washing both obtains the spherical CoS of black2Nanometer
Powder.The reaction system of the patent needs to carry out the regulation and calibration of pH value, and needs progress sufficiently clear after product is collected
Wash to remove accessory substance.
The content of the invention
It is controllable it is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind is easy to operate
The synthetic method of cobalt disulfide nanobelt package assembly in the strong titanium sheet substrate of property.
The purpose of the present invention can be achieved through the following technical solutions:
The synthetic method of cobalt disulfide nanobelt package assembly in a kind of titanium sheet substrate, using following steps:
(1) in titanium substrate cobalt hydroxide nanobelt synthesis:Cobalt salt and surfactant are weighed, water and N, N- diformazans is dissolved in
The mixed liquor of base formamide (DMF), is added dropwise hydrogenperoxide steam generator, is then transferred to reactor, the clean naked titanium sheet of input, envelope
Dress, is placed under high temperature and reacts, take out titanium sheet, clean and dry with ethanol and deionized water rinsing successively, obtains self assembly type
Co(OH)3/Ti;
(2) in titanium substrate cobaltosic oxide nano band preparation:Take Co (OH) made from step (1)3/ Ti is placed in tube furnace
