Catalysis plays a vital role in green chemistry by improving process efficiency, reducing waste, and minimizing environmental impact. A biochar-modified g-C3N4·SO3H (BCNSA) catalyst was developed using biochar derived from amla seed powder CNSA. CNSA synthesized via the reaction of g-C3N4 with chlorosulfonic acid. Both components were combined, pyrolyzed, purified, comprehensively characterized FTIR, XRD, FE-SEM, EDX, elemental mapping, TGA, DTA studies to confirm successful synthesis structural integrity. The demonstrated exceptional efficiency synthesizing bis-indole derivatives through reactions between substituted indoles (indole, 1-methyl indole, 6-chloro indole) carbonyl-containing compounds, including isatins (isatin, 7-(trifluoromethyl)isatin, 5-bromo isatin, 5-fluoro isatin), aldehydes, cyclo-ketones, dimedone, acetophenones. These carried out under simplified conditions water as solvent, promoting sustainability versatility. total 21 products within 5-45 minutes, achieving yields 80-98% showcasing catalyst's outstanding performance. Furthermore, method scaled up gram-level synthesis, metrics evaluated for all products, highlighting economic benefits this approach.
