Preparation and Characterization of Cellulose Nanocrystal Extraction From Pennisetum hydridum Fertilized by Municipal Sewage Sludge via Sulfuric Acid Hydrolysis

This research focuses on the preparation of cellulose nanocrystals (CNCs) from Pennisetum hydridum fertilized by municipal sewage sludge (MSS) through sulfuric acid hydrolysis in different acid concentrations (40–65%), temperature (room temperature ∼55°C), and reaction time (50–120 min). The results...
