Algae-mediated copper nanocatalyst for aerobic oxidation and dye decolourization via sustainable wastewater treatment.

ABSTRACT: In recent years, several physicochemical methods have been proposed for decolourising textile dyes; however, few have been adopted by the textile industry because of factors such as high cost, low efficiency, and limited applicability to a wide range of dyes. The current study focuses on synthesising algae-mediated Cu and CuO nanocatalysts (Alg-Cu and Alg-CuO) using natural waste materials from green algae. The synthesised Alg-CuO nanocatalyst was characterised and confirmed using SEM, TEM, UV, FT-IR, XRD, XPS, GC-MS, and TGA. An innovative and efficient technique for decolourising dyes through aerobic oxidation was implemented in industrial wastewater treatment. Various hydroxylamine substrates were successfully transformed into the desired aldehydes using an Alg-CuO nanocatalyst. In the
