technical field [0001] The invention belongs to the field of synthesis and preparation of nanomaterials, and in particular relates to a method for preparing copper oxide nanofibers. Background technique [0002] As a p-type narrow bandgap (1.2eV) semiconductor material, copper oxide is mainly used as the basic raw material for catalysts, gas sensors, high-temperature superconducting materials, etc. High catalytic activity, especially the catalytic activity of perchloric acid decomposition is in the forefront of metal oxides; it can effectively improve the carbon monoxide selectivity and detection sensitivity of the sensor; it can also be used as a model compound to explain the spectral characteristics of complex oxides. Nano-scale copper oxide nanofibers have infrared spectrum broadening, blue shift and splitting due to quantum size effect and surface effect. It has broad application prospects in fields such as emission, gas sensitive and humidity sensitive sensors. [000...

AI Technical Summary

Problems solved by technology

Usually, the size distribution of copper oxide nanofibers prepared by the dry method is narrow, and has high purity and good dispersibility, but the preparation process requires high equipment requirements, low total output per batch, and long synthesis and preparation cycle. The energy consumption is often huge, and it is difficult to meet the requirements of industrial scale production

However, the preparation of copper oxide nanofibers by wet method requires simple equipment, readily available raw materials, high purity and good uniformity of the product, but the preparation process is complicated, requires high operating experience, and the total output of a single batch is low. The preparation cycle is long, and it is often necessary to clean the final product or intermediate product, discharge a large amount of polluting waste liquid, and mostly stay in the stage of laboratory research and development or small-scale low-yield pilot production
