Enhanced Sonocatalytic Performance of Non-Metal Graphitic Carbon Nitride (g-C3N4)/Coconut Shell Husk Derived-Carbon Composite

This study focused on the modification of graphitic carbon nitride (g-C3N4) using which was obtained from pyrolysis coconut shell husk. The sonocatalytic performance synthesized samples then studied through degradation malachite green. In this work, pure g-C3N4, and carbon/g-C3N4 composites (C/g-C3N4) at different weight percentages were prepared characterized by XRD, SEM-EDX, FTIR, TGA surface analysis. effect amount in C/g-C3N4 10 wt% showed best catalytic activity. optimization conducted response methodology (RSM) with a central composite design (CCD) model. Three experimental parameters selected RSM including initial dye concentration (20 to 25 ppm), catalyst loading (0.3 0.5 g/L), solution pH (4 8). model found be significant reliable R2 value (0.9862) close unity. efficiency green optimized 97.11% under conditions = 20 ppm, g/L, 8 after min. reusability revealed high stability as sonocatalyst. short, has potential for industrial application since it is cost effective, reusable, sustainable, provides good performance.
