[0029] Example 1. Preparation of carbon hollow spheres
[0030] (1) Preparation of silica balls
[0031] Prepare the ethanol solution of ethyl orthosilicate (the volume ratio of ethyl orthosilicate to ethanol is 1:4) at 25°C and the ethanol solution of 30 mL and ammonia (the volume ratio of ammonia and ethanol is 1:4) 60mL (in this system, the volume ratio of ethyl orthosilicate, ammonia water and ethanol is 1:2:12), under vigorous stirring (stirring rate 1000r / min), 2mL of ethyl orthosilicate prepared above The ethanol solution was added to the ethanol solution of ammonia water prepared above, and stirred vigorously (stirring rate 1000r / min) for 10 minutes, and then at a lower speed (stirring rate 800r / min) the remaining ethyl orthosilicate prepared above The ethanol solution was added to the above-prepared ethanol solution of ammonia water, and stirring was maintained (agitating rate 800r / min) for 4h. After the reaction, the powder was collected by centrifugal water washing 3 t...

[0038] Example 2. Preparation of carbon hollow spheres
[0039] (1) Preparation of silica balls
[0040] Prepare the propanol solution of ethyl orthosilicate (the volume ratio of ethyl orthosilicate and propanol is 1:5) at 30℃ and the propanol solution of 30 mL and ammonia (the volume ratio of ammonia water and propanol is 1:4) 90mL (in this system, the volume ratio of ethyl orthosilicate, ammonia and propanol is 1:3.6:19.4), under vigorous stirring (stirring rate 1000r / min), 5mL of the above-prepared normal The propanol solution of ethyl silicate was added to the propanol solution of ammonia water prepared above, and stirred vigorously (stirring rate 1500r / min) for 20 minutes, and then at a lower speed (stirring rate 600r / min). The remaining propanol solution of ethyl orthosilicate was added to the above-prepared ammonia solution in propanol, and stirring was maintained (stirring rate 600r / min) for 6h. Afterwards, the powder was collected by centrifugal washing 5 times and dryin...
