| description | The invention provides a gold-urea complex nanosphere, a preparation method thereof, and a preparation method and an application of porous nano-gold. Compared with the prior art, the method for one-step preparation of the gold-urea complex nanosphere having a uniform size through a hydrothermal synthesis reaction has the advantages of no surfactant, no adjustment of the pH value, simplicity, and controllable conditions. The time is short, so the experiment efficiency is higher than that in the prior art; and amplification experiments are carried out, the gold-urea complex nanosphere is obtained at the same proportion in a first-step reaction in a multiplied manner, and a characterization result shows the uniformity of the spheres is same to the previous uniformity. Raw materials are simpleand clean, only chloroauric acid and urea are reacted in an aqueous solution, and no surfactants or other substances are added. The gold-urea complex prepared in the invention undergoes calcination,shady heating or electron |
