Description
Technical field
The invention belongs to photocatalysis technology field, is related to a kind of Pd-Ni-P ternarys non-crystaline amorphous metal and nano titanium oxide
The preparation method of composite photo-catalyst and its application in light decomposes aquatic products hydrogen.
Background technology
(1) non-crystaline amorphous metal has excellent mechanical property, electric property, magnetic performance and chemical property.Research shows,
Amorphous alloy has obvious catalytic action to some chemical reactions.Pd-Ni-P alloys can shape in very wide compositing range
Into amorphous structure, its excellent physical-chemical performance all has a good application prospect in machinery, electro-catalysis etc..This
Invention prepares Pd-Ni-P ternary non-crystaline amorphous metals using electroless plating method, and its process is simple, and equipment requirement is simple.
(2) as expanding economy and the growth of population, traditional fossil fuel result in a series of pollution problem, sternly
The sustainable development of human society is threaten again.Therefore, facing mankind huge energy crisis and environmental problem.Hydrogen is not only
With cleaning, reproducible advantage, at the same also have the characteristics that to have good burning performance, energy conversion rate it is high, be considered as optimal
Clean energy resource.In recent years, photocatalytic hydrogen production by water decomposition increasingly by researcher is paid close attention to.The invention provides a kind of new light
The preparation method of catalyst, obtain the nano composite photo-catalyst of a kind of better performances.
(3) nano titanium oxide is a kind of new high-performance inorganic nanometer materials, is both had with general nano material
Standby skin effect, quantum size effect and macro quanta tunnel effect, there is the unique photocatalytic of semi-conducting material, light again
The premium properties such as electric transformational and photocatalysis stability, so nano titanium oxide is the conductor photocatalysis material of most study
Material.Novel photocatalyst is developed, it is all possessed good photocatalysis Decomposition aquatic products hydrogen under ultraviolet light and radiation of visible light
Performance, tool are of great significance.Ternary non-crystaline amorphous metal/nano titania that the present invention is prepared using low-temperature solid-phase method is multiple
The speed that closing light catalyst decomposes aquatic products hydrogen is higher.
The content of the invention
It is an object of the invention to provide a kind of Pd-Ni-P ternarys non-crystaline amorphous metal/titanic oxide nano compound photocatalyst
Preparation method.Ternary non-crystaline amorphous metal is obtained by electroless plating method, then ternary non-crystaline amorphous metal/dioxy is prepared using low-temperature solid-phase method
Change titanium nano composite photo-catalyst.This method is simple to operate, and can be realized by adjusting technological parameter to ternary non-crystaline amorphous metal
The accurate control of non-crystaline amorphous metal content in component and nano composite photo-catalyst.
The preparation method of novel photocatalyst of the present invention comprises the following steps：
(1) 0.5~10g hypophosphites is added into 10~200mL to go from obtained solution A in water；
(2) 0.1~5.0mL concentrated hydrochloric acids are slowly added dropwise in the inorganic palladium salts of 0.01~0.2g, after stirring 10~60min, drop
Add 0.5~10 mL ammonia spirits, after continuing 10~60min of stirring, solution becomes colorless, obtained solution B；
(3) after l0~200mL deionized waters being heated into 40~80 DEG C in water-bath, 0.5~10g boron is sequentially added
Solid is treated in acid, 0.5~10g inorganic nickels, 0.5~10g sodium citrates, 0.5~5g ammonium chlorides, 0.5~5g ammonium sulfate, stirring
Material is completely dissolved rear obtained solution C；
(4) solution B and solution C are mixed, by add sodium hydroxide solution adjust the pH value of mixed solution for 7.0~
9.0 scopes, obtained solution D；
(5) solution A is added in solution D, reacts 1~12h at room temperature, solid matter is put into 60 DEG C of baking after filtering
