Description
Technical field
The invention belongs to the synthesis technical field of Red copper oxide, be specifically related to a kind of grade cuprous oxide particle and synthetic method thereof.
Background technology
After second industrial revolution, industrial development is rapid, especially chemical engineering industry, and prospect is considerable.In bringing huge economic benefit, environmental pollution also becomes 21 century one of the problem of headache the most gradually.The photocatalysis technology of complying with the epoch and give birth to has brought hope undoubtedly.Announce for the first time Cu from Ikeda in 1998
2o can be after generation of hydrogen by dissociation of water and oxygen as photocatalyst, Cu
2o is taken seriously and becomes in the world the focus of research as the performance of photocatalyst.
Red copper oxide, oxide compound, copper is wherein monovalence, is generally reddish-brown solid, the organic solvent such as water-soluble and alcohol is easily oxidized to cupric under acidic conditions hardly, easily forms colourless title complex in liquor ammoniae fortis.Red copper oxide is a kind of important p-type semiconductor material, and its energy level difference is about 2.2eV, is compared to TiO
23.2eV, much lower, can under the radiation of sunlight, produce electron-hole pair completely, cause light-catalyzed reaction.And diameter is better at the catalytic effect of the Red copper oxide of nanoparticle sub level, because it has quantum size effect, make its valence band and conduction level become discrete energy levels, energy gap will broaden, and valence band current potential can become corrigendum, and that conduction band price can become is more negative.In other words be exactly that Nano semiconductor particles has stronger oxidation capacity and reducing power, therefore a lot of experts think that nano cuprous oxide can replace titanium dioxide and become photodissociation catalyzer of new generation.
Red copper oxide, except being widely used aspect photodissociation catalyzer, also has application prospect at aspects such as antifouling, sterilant, eelctro-catalysts.
The known preparation about grade cuprous oxide at present, mainly contain solid-phase synthesis, hydrothermal method, sedimentation etc., the inadequate environmental protection of ubiquity agents useful for same, cannot regulate and control Red copper oxide size and pattern, because obtaining the grade cuprous oxide of small scale more to such an extent as to cannot bring into play better the technological deficiencies such as its chemical property.
