NOVELTY - Complex of copper bismuth bimetallic coordination polymer with graphene, comprises 1-2 pts. wt. basic copper carbonate, 2-6 pts. wt. bismuth nitrate pentahydrate, 2-3 pts. wt. 4,4'- bipyridine, 3-5 pts. wt. 3,5-pyrazole dicarboxylic acid and less than or equal to 50 pts. wt. graphene. USE - The complex of copper bismuth bimetallic coordination polymer with graphene is useful to degrade rhodamine B solution in visible light (claimed). ADVANTAGE - The method does not use strong acid, strong alkali, strong oxidant or toxic reagents, is economical and environmentally-friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing complex, comprising simple hydrothermal synthesis method, taking the above mentioned raw materials and dissolving in 5-15 ml water, sonicating for half an hour, carrying out magnetic stirring for 10 minutes in the reaction kettle with 20-50 ml polytetrafluoroethylene lining, sealing the reaction kettle and allowing to react for 24-72 hours at 150-210 degrees C, allowing to naturally cool to room temperature, filtering and separating the mixture to obtain the powder, washing the crystals many times with ethanol and distilled water and drying overnight at room temperature.
