Abstract
Production of cuprous oxide nano-column array is carried out by washing Cu pieces in hydrochloric acid and acetone for 10-15 mins separately, washing by de-ionized water, blow drying for Cu pieces, putting clean Cu pieces into horizontal tube furnace, inducing into air by 3-5 ml/min, raising temperature to 335-345 degree by 8-10 degree /min, keeping temperature for 120-150 mins, and naturally cooling to obtain final product. It's simple, cheap and has no environmental pollution.
Description
Technical field
The invention belongs to the nano material preparation technical field, a kind of method for preparing cuprous nano-column array especially is provided.
Background technology
Red copper oxide (Cu
2O) be a kind of p N-type semiconductorN, the about 2.0eV of energy gap, be rare can be by the semiconductor material of excited by visible light, being widely used in fields such as solar cell, gas sweetening, wastewater treatment, sterilization, deodorizing, agricultural chemicals and anti-fouling ship paint, also is catalyzer commonly used in the petroleum chemical industry.Work as Cu
2The size of O is reduced to after the nanometer scale, because of it has bigger specific surface area and good Surface Physical Chemistry character makes it have great application prospect at aspects such as solar cell, microelectronic device, gas catalysis, gas sensors.Had much about Cu at present
2The report of O nanostructure goes out the Cu of different diameter as employing electrochemical production such as Nikesh
2O nano particle [V.V.Nikesh, A.B.Mandale, K.R.Patil, Shailaja Mahamuni, Materials Research Bulletin, 40 (2005) 694-700], M.Z.Wei etc. adopt hydro-thermal synthetic method to obtain Cu
2O nano-pillar [M.Z.Wei, N.Lun, X.C.Ma, S.L.Wen, Materials Letters, 61 (2007) 2147-2150], employing chemical precipitation methods such as Yu Ying are prepared stable Cu
2O whisker [Yu Ying, Du Feipeng, Yang Shengjun, Li Jialin, the patent No.: 03128315.2], Wang Wenzhong etc. adopt reduction method to obtain Cu
2O nano wire [Wang Wenzhong, Wang Guanghou, the patent No.: 02137806.1].But, so far, do not see about Cu as yet
2The report of O nano column array, the present invention adopts first in the world and extremely simply the method for copper sheet low temperature thermal evaporation is successfully prepared big area Cu
2The O nano column array.The present invention does not need complicated processing unit, only need simple tube furnace to get final product, and operating procedure is simple, and cost is also very low.
Summary of the invention
The object of the present invention is to provide a kind of method for preparing cuprous nano-column array, adopt the Cu substrate preparation to go out Cu
