In recent years, several physicochemical methods have been proposed for decolourising textile dyes; however, few adopted by the industry because of factors such as high cost, low efficiency, and limited applicability to a wide range dyes. The current study focuses on synthesising algae-mediated Cu CuO nanocatalysts (Alg-Cu Alg-CuO) using natural waste materials from green algae. synthesised Alg-CuO nanocatalyst was characterised confirmed SEM, TEM, UV, FT-IR, XRD, XPS, GC-MS, TGA. An innovative efficient technique dyes through aerobic oxidation implemented in industrial wastewater treatment. Various hydroxylamine substrates were successfully transformed into desired aldehydes an nanocatalyst. process oxidation, 2-(2-amino-ethyl)-aminoethanol can be converted 2-(2-amino-ethyl)acetaldehyde, resulting 96% product conversion within 4 min. addition, used investigate dye decolourisation CBB G250 dye. exhibited excellent properties; 20 min, 85% achieved. As result, synthesis is viable medium producing with bond energies decolourisation. Finally, separated reused following process. This method has
