Abstract

The invention belongs to the technical field of preparation of nano materials, and discloses a preparation method of an AlOOH nanosheet-based 0D/2D composite material, and the method comprises the following steps: preparing a sea urchin-like copper oxide-boehmite (CuO/AlOOH) nano composite material by using a hydrothermal method; using copper chloride dihydrate and aluminum chloride hexahydrate asraw materials, urea as a precipitator and deionized water as a solvent for perform a constant-temperature reaction at a specific temperature, and preparing a uniformly dispersed urchin-shaped CuO/AlOOH nano material through centrifugal separation, sample washing and drying. The prepared 0D/2D nano composite material efficiently catalyzes sodium borohydride to reduce p-nitrophenol through two processes of adsorption and hydrogenation. The method is simple in preparation process, short in period and low in cost, can be used for large-scale industrial production, and has good economic benefitsand environmental benefits.

Description

technical field [0001] The invention belongs to the technical field of nanomaterial preparation, and in particular relates to a preparation method and application of an 0D / 2D composite material based on AlOOH nanosheets. Background technique [0002] Zero-dimensional (0D) nanomaterials, also known as quantum dots, have broad application prospects due to their ultrafine size (<10 nm), large surface area, fast charge transfer rate, unique optical properties, and excellent catalytic performance. catalyst. However, it is still a great challenge to achieve good dispersion of zero-dimensional (0D) nanomaterials and avoid their intrinsic aggregation, which also limits the practical application of zero-dimensional (0D) nanomaterials in the field of catalysis. Therefore, finding an effective support material to combine with it, which can not only maintain the large surface area and excellent characteristics of 0D nanomaterials, but also solve the above problems, has become a curr...
