Technical field
The invention belongs to bloodstone photocatalyst technology field, and in particular to a kind of bloodstone light with twin structure is urged
Agent and preparation method thereof.
Background technology
Photocatalysis has in the field such as the renewable sources of energy and degraded environmental contaminants due to its high efficiency, high energy source utilization rate
There iss very important and status.Therefore the photochemical catalyst of function admirable is explored, and realizes the degraded of simulated environment pollutant
Process has extensive and profound significance.
Many conductor oxidates, sulfide and nitride is had all to have photocatalytic activity.However, most of oxides
Absorption edge which has limited its use to most of solar spectrum only in ultraviolet region.Although sulfide and nitride have relatively
Low band gap, but stability of these materials in aqueous medium is very poor.For overcoming these inferior positions, bloodstone becomes and enjoys recently
The semiconductor light-catalyst of concern.Bloodstone (α-Fe2O3) be in most of aqueous environment (pH>3) most stable of iron oxidation in
Thing.Due to its narrow band gap about 2.2eV, the absorbent spectral region of bloodstone can reach 600nm, you can be up to utilizing
