Abstract
The paper concerns the production of a hybrid material based on the precipitation of Zn/Al hierarchical structures onto cellulose surface through urea hydrolysis method. The assessment of the morphological, spectroscopic and sorption properties is carried out. Morphological and spectroscopic analyses proved the deposition of inorganic structures onto cellulose. The improvement of thermal stability of hybrid material was even evaluated by TGA analysis. Besides, band gap energy of 3.71 eV was evaluated through Kubelka-Munk theory. Water sorption isotherms are investigated demonstrating the reduction of sorption coefficient after the surface modification of cellulose (4.60 and 8.23 g/g*1/atm for Cellulose and Zn/Al Cellulose). Oil adsorption tests were finally carried out by using different oils while the potential antioxidant activity (15.3% for Zn/Al Cellulose and 0.15% for Cellulose) was demonstrated by performing DPPH antioxidant assay.
