Embodiment 1
[0027] An indium oxide (In 2 o 3 ) The preparation method of cube is to carry out according to the following steps:
[0028] A. Weigh the molar ratio of 1:0.5 indium nitrate (In(NO 3 ) 3 4.5 H 2 O) and urea, dissolved in 100 mL of deionized water, was configured into a uniform colorless and transparent solution after magnetic stirring for 30 min;
[0029]B. Transfer the solution obtained in step A to a quartz container with a capacity of 250mL, place it in a microwave reactor, heat up to 80°C, and heat it for 15min with a power of 600W, then cool naturally and collect the microwave product;
[0030] C, centrifuging the microwave product obtained in step B, washing with deionized water and absolute ethanol three times respectively;
[0031] D, the centrifuged product obtained in step C was dried in the air at 60°C for 6 h to obtain indium hydroxide (In(OH) 3 )Precursor;
[0032] E, the indium hydroxide (In(OH) obtained in step D 3 ) precursors were calcined in a muffle ...
