Highly important research significance.
Up to the present, copper-based delafossite material, including high temperature solid-state method, collosol and gel can be prepared there are many method
Method, pulsed laser deposition, sputtering method, chemical vapour deposition technique, hydro-thermal method etc..In the method that these prepare target product,
Hydro-thermal method is a kind of relatively green simple preparation method, crystalline oxides can be directly obtained from aqueous medium, it is considered to be ring
Border is polluted less, cost is relatively low, is easy to a kind of commercialized method with stronger competitiveness.With traditional solid phase high-temperature sintering process
Prepare delafossite structure CuCoO2Crystalline material compares, hydro-thermal method reactant is placed under special environment (closed, low temperature,
High pressure etc.) synthetic reaction occurs, two complicated experimental implementations of high-temperature calcination and ball milling are avoided, also prevention introduces impurity and makes
At fault of construction.Meanwhile by adjusting hydrothermal reaction condition, such as reactant presoma component, reaction time, temperature, pressure
And solution ph etc., it is easy to get to high purity, crystal form is good, pattern and size tunable delafossite CuCoO2Material.
Currently, the research report about the copper-based delafossite material of hydrothermal reaction at low temperature synthesis series focuses mostly in CuAlO2,
CuGaO2, CuCrO2And CuFeO2On, it does not find temporarily any using hydrothermal reaction at low temperature synthesis delafossite structure CuCoO2Material
Research report.Therefore, it is badly in need of stepping up to carry out the copper-based delafossite CuCoO of hydro-thermal method synthesis2The basic research of semiconductor material, system
Hydro-thermal preparation process is optimized and revised, its hydrothermal growth mechanism is inquired into, regulates and controls its characteristic of semiconductor comprehensively, it is various novel to be suitable for
In photoelectric functional device.
