NOVELTY - Synthesis of graphene oxide incorporated copper bismuth nanorods involves adding graphite powder and sodium nitrate or potassium nitrate to sulfuric acid or nitric acid, stirring the solution, slowly adding potassium permanganate or potassium persulfate to the stirred solution, adding sulfuric acid to the brownish grey solution and stirring the brownish grey solution, dripping hydrogen peroxide, washing with 1M hydrochloric acid, rewashing, drying the muddy graphene oxide solution and exfoliating, dissolving bismuth (III) nitrate pentahydrate in ultrapure water with magnetic stirring, to produce a homogeneous solution, dissolving copper chloride or iron chloride or zinc chloride or calcium chloride in the homogeneous solution, dripping 6M sodium hydroxide solution or potassium hydroxide solution. USE - Synthesis of graphene oxide incorporated copper bismuth nanorods used for environmental decontamination of organic pollutants (all claimed) e.g. phenolic compounds. ADVANTAGE - The method is simple, and inexpensive, and enables synthesis of graphene oxide incorporated copper bismuth nanorods with efficient photodegradation ability. DETAILED DESCRIPTION - Synthesis of graphene oxide incorporated copper bismuth nanorods involves adding graphite powder and sodium nitrate or potassium nitrate to sulfuric acid or nitric acid, stirring the solution, and keeping the solution on an ice bath, with the ratio of the graphite powder to the sulfuric acid or nitric acid being 1:18.75, and the ratio of the sodium nitrate or potassium nitrate to the sulfuric acid or nitric acid being 1:25, slowly adding potassium permanganate or potassium persulfate to the stirred solution, and continuously stirring the solution with the potassium permanganate or potassium persulfate, with the ratio of the potassium permanganate or potassium persulfate to the sulfuric acid or nitric acid being 1:4.2, removing the ice bath, and continuously stirring the solution until the color of the solution changes from dark green to brownish grey, adding sulfuric acid to the brownish grey solution and stirring the brownish grey solution, with the ratio of the sulfuric acid or nitric acid into which the graphite powder and the sodium nitrate or potassium nitrate are added to the sulfuric acid mixed into the brownish grey solution being 1:2.7, dripping hydrogen peroxide to the brownish grey solution under continuous stirring to synthesize graphene oxide, with the ratio of the hydrogen peroxide to the sulfuric acid mixed into the brownish grey solution being 1:20, washing the synthesized graphene oxide with 1M hydrochloric acid by centrifugation, and repeating the washing to remove the divalent sulfate ion, rewashing the washed graphene oxide with ultrapure water by centrifugation to remove the chloride ion and until the solution becomes muddy, drying the muddy graphene oxide solution to produce dry graphene oxide powder, and exfoliating the graphene oxide powder, dissolving bismuth (III) nitrate pentahydrate in ultrapure water that comprises nitric acid or sulfuric acid or phosphoric acid, with magnetic stirring, to produce a homogeneous solution, with the ratio of the bismuth (III) nitrate pentahydrate to the ultrapure water being 1:5.3, and the ratio of the ultrapure water to the nitric acid or sulfuric acid or phosphoric acid is 5:1, dissolving copper chloride or iron chloride or zinc chloride or calcium chloride in the homogeneous solution, with the ratio of the bismuth (III) nitrate pentahydrate to the copper chloride or iron chloride or zinc chloride or calcium chloride being 3.8:1, weighing 6M sodium hydroxide or potassium hydroxide and dissolving the weighed 6M sodium hydroxide in water, dripping 6M sodium hydroxide solution or potassium hydroxide solution to the homogeneous solution with the copper chloride or iron chloride or zinc chloride or calcium chloride, under constant stirring, to form a suspension, adding 5 mL of 1 mg/mL exfoliated graphene oxide to the suspension, and continuous stirring at room temperature, to produce graphene oxide incorporated copper bismuth nanorods, collecting the produced graphene oxide incorporated copper bismuth nanorods, and washing with deionized water and ethanol, and drying the washed graphene oxide incorporated copper bismuth nanorods.
