The overpotential of thermodynamic voltage (1.23V) is used for the decomposition (2H of water2O→H2+1/2O2), the process that electro-catalysis generates oxygen is
Process (the acidic environment 2H slowly occurred on mechanics2O→4H++O2+4e-, 4OH under alkaline environment-→2H2O+O2+4e-).Therefore,
We need a kind of effective electro-catalysis to produce the catalyst of oxygen to promote water decomposition to react, and reduce and react required overpotential,
Thus the energy source efficiency enhanced.Currently, it is based on IrO2Or RuO2Elctro-catalyst can it is most effective acid or
Catalysis production oxygen reaction under person's alkaline environment, still, these precious metal material reserves are low and expensive, hinder their reality
Using.In this case, there is Development of Novel the novel electro-catalytic production oxygen of the rich reserves of high activity while price economy to urge
Agent is necessary.
Currently, VPO catalysts are produced in the electro-catalysis based on 3d transition metal, and it is cheap due to rich reserves, it is environmental-friendly
And the advantages that good active, is as the most possible material for substituting noble metal base electro-catalysis and producing VPO catalysts.They are good
Electro catalytic activity can pass through single or mixed oxide, hydroxide, phosphate, the embodiments such as bromide and sulfide.
Layered double hydroxide (LDH) therein, general. formula is [M2+ 1-xM3+ x(OH)2]x+[An-x/n]x-.mH2O, i.e., by one
The anion of the balancing charge of the layers of metal hydroxides and interlayer by positive charge of serial stratiform forms.Many researchs are
It confirms the importance of different transition metal combinations, however, their performance still needs further to be promoted to meet
The needs of practical application.Simultaneously with the extensive research of two-dimensional ultrathin nanometer sheet, they are in electricity, optics, the fields such as magnetism
Advantage all gradually embodies, and in terms of oxygen is produced in electro-catalysis, the electro-catalysis production VPO catalysts based on ultrathin nanometer piece equally have very big
Advantage.For example, there is two-dimensional ultrathin piece high specific surface area, theoretical value to reach 1000m2/g.At this point, surface exposure is all
The electronics conductive process that is coupled due to quick proton of transition metal atoms and the diffusion of quick intermediate, can effectively promote
Into redox reaction.Simultaneously compared to more reactivity sites of bulk material exposure, reaction can be effectively promoted
Catalytic activity.The more extensive double-metal hydroxide such as NiFe-LDH of research at present, the binary such as NiCo-LDH, NiV-LDH
Material can be used for electro-catalysis production oxygen reaction, however their performance also need to further promoted meet electro-catalysis production oxygen it is anti-
The needs answered.Ternary layered hydroxide materials are formed to adjust its electronic structure by the doping of third element as a result,
Its electro catalytic activity can further be optimized, obtain the elctro-catalyst with superior electrocatalysis characteristic.
