Abstract
Disclosed is a method of manufacturing carbonized fine cellulose, which enables the formation of carbonized nano-sized cellulose by subjecting cellulose to drying, carbonization, and pulverization by means of shock waves using ultrasonic waves and microbubbles, thus realizing mass producibility, making it possible to fabricate a carbonized nano-sized material having uniform quality, and reducing the manufacturing costs. The carbonized fine cellulose is in the form of a nano-sized uniform carbon powder, and can thus be utilized as a catalyst support in various forms, such as fuel cell electrodes, electrodes of energy storage devices such as supercapacitors or secondary batteries, catalyst supports for micro-nano hybrid reactors, etc.
