Benefits of technology

This patented technology helps create high-quality ceramics with improved properties through methods like hydrocracking or thermal decomposition processes. By adding water at specific temperatures for certain steps during these process stages, we get better quality materials without damaging them themselves.

Problems solved by technology

This patents discuss different ways to develop efficient photosensitive agents used in industry by developing novel structures or studying them chemically based upon specific properties. While current techniques involve expensive processes like sputter coating, laser ablation, solvothermal synthesis, and other approaches, these technical problem addressed through this patented method can lead towards improved photoactive agent designs and development strategies.

Embodiment 1

[0033] A flower-shaped ErBO composed of multi-layered petals 3 The preparation method of photocatalyst is characterized in that, adopts hydrothermal method to synthesize ErBO 3 , including the following steps:

[0034] The first step is to weigh 0.02mol of erbium oxide medicine, put it into a beaker after weighing, then add the magnetic rotor into the beaker, and slowly add 3ml of HNO dropwise with a dropper 3 (w=65%) solution, during the process, a constant temperature magnetic stirrer is heated and stirred, and the heating temperature is 40°C. After the erbium oxide is completely dissolved, a clear solution A is obtained. It should be noted that each drop of nitric acid solution is added dropwise and stirred for five minutes. Add the second drop of nitric acid solution dropwise to ensure that the nitric acid used can just dissolve the erbium oxide, and add too much or too little HNO 3 It will affect the shape of the final powder.

[0035] The second step is to weigh 0.04m...

Embodiment 2

[0040] Synthesis of ErBO by Hydrothermal Method 3 Powder, the specific operation process is as follows:

[0041] The first step is to weigh 0.03mol erbium oxide medicine, put it into a beaker after weighing, then add the magnetic rotor into the beaker, and slowly add 4ml HNO drop by drop with a dropper 3 (w=65%) solution, during the process, a constant temperature magnetic stirrer is heated and stirred, and the heating temperature is 50°C. After the erbium oxide is completely dissolved, a clear solution A is obtained. It should be noted that each drop of nitric acid solution is added dropwise and stirred for five minutes. Add the second drop of nitric acid solution dropwise to ensure that the nitric acid used can just dissolve the erbium oxide, and add too much or too little HNO 3 It will affect the shape of the final powder.

[0042] The second step is to weigh 0.06mol boric acid. It should be noted that the molar ratio of erbium oxide and boric acid should be 1:2. Once the...

Abstract

The invention discloses a preparation method of a flower-ball-shaped ErBO3 photocatalyst composed of multiple lamellar petals, which adopts a hydrothermal method to synthesize ErBO3 powder, and comprises the following steps of S1, slowly adding an HNO3 solution into erbium oxide, and heating and stirring until the erbium oxide is completely dissolved to obtain a solution A, S2, mixing and heatingboric acid and water to obtain a solution B, S3, mixing and heating the solution A and the solution B to obtain a solution C, and slowly adding an alkaline solution into the cooled solution C until the solution C is weakly alkaline, and S4, heating the weakly alkaline solution C to react, separating the precipitate in the solution C from the clear liquid, and drying to obtain the flower-ball-shaped ErBO3 photocatalyst composed of multiple lamellar petals.
