Rapid, inexpensive, and low-power/solar light-driven photocatalytic degradation of organic pollutants to deal with annually produced trillion tons synthetic dye wastewater prevent water scarcity issues, ecotoxicological risks, human health has always been challenging. To overcome this limitation, the present study synthesized earth-abundant, inexpensive copper oxide nanosheets using a simple single-step hydrothermal route. The structural, physicochemical, functional properties have characterized several characterization techniques. activity was studied for two commonly industrially used dyes, Methylene Blue (MB) Rhodamine B (RhB). importance work is usage cheap commercially available Phillips UV light (11 W) as well direct sunlight. With optimized conditions, almost complete both dyes achieved within 35 minutes under low-power 70 by illumination natural enhanced performance can be correlated synergetic effect higher charge transfer mechanism, good catalytic 'active surface area' availability (13.2 m2/g), parameters that affect reaction efficacy. Additionally, five repeated uses without sacrificing confirmed their stability sustainability promising candidate large-scale industrial textile remedies.
