Limestone, a raw material in cement industry, had been reported to be used for sequestrating the CO2. But its efficiency was dramatically reduced after several cycles due to the “sintering” phenomena. Here we have provided a new method to enhance the CO2 sequestration ability of limestone by using small amount of carbon as an additive. A variety of carbon, such as carbon black, graphite, bamboo woods and coconut woods were studied. Our results show that coconut woods is the best carbon source and it has the performance of 13% increasment of efficiency with 2 wt% adding amount.
