Embodiment 1

[0020] Use a pipette to pipette 8mL of 0.36mmol / L glucose solution into a 50mL polytetrafluoro-lined hydrothermal kettle, then put 1.0mmol basic copper carbonate powder into the above hydrothermal kettle, and use a glass rod to After stirring evenly, tighten and seal the hydrothermal kettle, place it in an oven at 190°C, and after reacting for 20 hours, wash the product obtained by the reaction with distilled water for 3 to 5 times, centrifuge and dry at room temperature at 20°C for 24 hours to obtain the size Cu assembled into nanosheets of 3-5 μm 2 O-CuO composite oxide. The SEM characterization of the synthesized complex was as follows figure 1 shown by figure 2 The XRD crystal structure shown shows that the synthesized product is Cu 2 O-CuO composite oxide.

Embodiment 2

[0022] Use a pipette to pipette 8mL of 0.06mmol / L glucose solution into a 50mL polytetrafluoro-lined hydrothermal kettle, then put 1.0mmol basic copper carbonate powder into the above hydrothermal kettle, and use a glass rod to After stirring evenly, tighten and seal the hydrothermal kettle, place it in an oven at 160°C, and after reacting for 5 hours, wash the product obtained by the reaction with distilled water for 3 to 5 times, centrifuge and dry at room temperature at 15°C for 10 hours to obtain the size Cu assembled into nanosheets of 2.5-4 μm 2 O-CuO composite oxide.

Embodiment 3

[0024] Use a pipette to pipette 8mL of 0.60mmol / L glucose solution into a 50mL polytetrafluoro-lined hydrothermal kettle, then put 1.0mmol basic copper carbonate powder into the above hydrothermal kettle, and use a glass rod to After stirring evenly, tighten and seal the hydrothermal kettle, place it in an oven at 220°C, and after reacting for 10 hours, wash the product obtained by the reaction with distilled water for 3 to 5 times, centrifuge and dry at room temperature at 30°C for 20 hours to obtain the size Cu 2 O-CuO composite oxide.

Abstract

The invention discloses a preparation method of a Cu2O-CuO composite oxide. The preparation method comprises the following steps: adding a glucose solution with certain concentration and a certain amount of basic copper carbonate powder into a hydrothermal kettle, fully stirring, placing the hydrothermal kettle in an oven with a preset temperature, taking out a product after reacting for a period of time, and carrying out vacuum drying on the product to obtain the Cu2O-CuO composite oxide. According to the preparation method, the glucose content, the reaction temperature and the reaction time are adjusted to control the preparation, and no surfactant or acid-base reagent is added, so that the whole process is environment-friendly, the reaction condition are mild, the operation is convenient and efficient, the controllability and repeatability are good, and a high-yield spherical Cu2O-CuO composite oxide assembled by nanometer pieces can be prepared.

Description

technical field [0001] The invention belongs to the technical field of preparation methods of two-component metal oxides, in particular to a Cu 2 The preparation method of O-CuO composite oxide. Background technique [0002] In recent years, semiconductor materials have received extensive attention and applications due to their remarkable development potential in the fields of energy and environment. Among many semiconductor materials, copper oxide is one of the most concerned semiconductor materials because of its narrow bandwidth, non-toxic characteristics, and low price. Cu 2 O and CuO, as two types of oxides in different valence states of copper, have special properties in light, electricity, and magnetism, so they are widely used in the fields of environmental catalytic purification, photocatalytic degradation, magnetic materials, and sensing. Immeasurable application value. [0003] As a semiconductor functional material, its chemical composition and microstructure...
