WebRice straw has been chosen, because it is rich in carbon-based compounds and can therefore be used for graphene production. Rice straw consists of four major components, namely hemicellulose (35.7%), cellulose (32%), lignin (22.3%), and small portions of lignocellulose material that account for ~ 10% of the total weight. The pre-treatment, or ...
