- Аннотация: With the growing demand for fuel and simultaneous pollution caused by the use of traditional fuel sources, the quest for clean energy source is the biggest challenge forward. Thus, has given way to hydrogen economy. Herein, the successful fabrication of novel cellulose acetate (CA)/palladium acetate (PdOAc)2 blend membranes for hydrogen gas separation with respect to carbon dioxide, and methane gases is reported. Pristine CA and CA/(PdOAc)2 blend membranes with various concentrations (0.5, 0.75 and 1 wt %) of (PdOAc)2 were prepared via vapor induced phase separation (VIPS) method. The membranes were investigated through various techniques such as ATR-IR spectroscopy to study the interaction between the CA and (PdOAc)2. Followed by morphological study by FESEM which showcased homogeneous blending between CA and (PdOAc)2. XRD patterns revealed the characteristic peaks denoting (PdOAc)2 and the change in crystallinity of the membranes upon blending. The alteration in mechanical strength of the blends due to incorporation of (PdOAc)2 into CA matrix was deliberated by tensile strength analysis. Gas experiments showcased permeability in the descending order of H2>CO2>CH4, with a selectivity of 2.02, 68.5 and 34 for H2/CO2, H2/CH4 and CO2/CH4 separation respectively for the optimum membrane. The study was able to demonstrate a simple yet effective way to fabricate membranes with decent separation efficiency for hydrogen gas giving boost to ongoing expedition to use hydrogen gas as a fuel.
