Abstract

The invention discloses amorphous Sb-doped zinc tartrate micro-nano spheres. The diameters of the micro-nano spheres are 300-1200nm, and the atom percent of Sb and Zn is 0.06-15.0%. The preparation method comprises the following steps: (1) dissolving zinc nitrate and hexamethylenetetramine in water, adding equal mol of antimony ions and tartrate, and evenly stirring to obtain growth mother liquor for hydrothermal reaction; and (2) putting the growth mother liquor into a reaction kettle, keeping the temperature of 80-120 DEG C for 0.5-5 hours, standing, taking the precipitate, repeatedly flushing, centrifugalizing and drying. The invention has the advantage of simple preparation technique, and the particle sizes and the doping amount of the Sb-doped zinc tartrate micro-nano spheres can be regulated within a certain range.

Description

technical field [0001] The invention relates to amorphous Sb-zinc tartrate-doped micro-nanospheres and a preparation method thereof, belonging to the technical field of doped organic metal salts. Background technique [0002] Organometallic salts have become a research hotspot in recent years because of their broad application prospects in the fields of light, electricity, magnetism, adsorption and catalysis. The organometallic salt prepared by Jung Soo Seo et al. using D-tartaric acid and zinc ions has good catalytic activity (Jung Soo Seo et al. Nature 404(2000) 982). At the same time, zero-dimensional organometallic micro-nanostructures have many novel properties and can be used as building blocks of nanodevices such as molecular recognition, chemical sensing, and heterogeneous catalysis; using doped organometallic micro-nanostructures as precursors, after high temperature After heat treatment, micro-nano-sized doped oxide semiconductors can be obtained, so organometalli...
