成果简介	NOVELTY - Synthesizing microwave pyrolysis biochar based metallic silver catalyst involves (i) dispersing 0.5 g biochar in 120 mL of distilled water, adding 0.5 N g of ferrous chloride (FeCl2.4H2O) and 1.37 g of ferric chloride (FeCl3.6H2O) in the solution, warming to 35℃ for a duration of 3 hours (h), raising the temperature to 60℃, and adding incrementally 10 ml ammonium hydroxide (NH4OH), stirring the mixture for 1 h, centrifuging the product, giving water wash for 2-3 times, subjecting the product in hot oven at 60℃ for 2 h; (ii) washing the collected Plumeria obtuseleaves for removing dust, sterilizing with deionized water to remove the contaminants, 24 g of dried leaves were finely chopped and adding into a beaker containing 250 mL of deionized water, stirring the mixture at 60℃, maintaining for 2 h, cooling, and filtering the solution containing celery leaf extract. USE - Method for synthesizing microwave pyrolysis biochar based metallic silver catalyst. ADVANTAGE - The method is a simple and scalable process, optimum dose with more yield, biocompatible, has enhanced magnetic properties, low cost, and eco-friendly in nature. DETAILED DESCRIPTION - Synthesizing microwave pyrolysis biochar based metallic silver catalyst involves (i) dispersing 0.5 g biochar in 120 mL of distilled water, adding 0.5 N g of FeCl2.4H20 and 1.37 g of FeCl3.6H2O in the solution, warming to 35℃ for a duration of 3 hours, raising the temperature to 60℃, and adding incrementally 10 ml ammonium hydroxide, stirring the mixture for 1 h, centrifuging the product, giving water wash for 2-3 times, subjecting the product in hot oven at 60℃ for 2 h; (ii) washing the collected Plumeria obtuseleaves for removing dust, sterilizing with deionized water to remove the contaminants, 24 g of dried leaves were finely chopped and adding into a beaker containing 250 mL of deionized water, stirring the mixture at 60℃, maintaining for 2 h, cooling, and filtering the solution containing celery leaf extract; and (iii) combining a mixture of biochar/Fe3O4with 20 ml of distilled water, stirring for 30 minutes (min), adding 50 ml of silver nitrate (AgNO3) to the blend, stirring at room temperature for 5 h, raising the reaction temperature to 65℃, stirring for an additional 20 min, adding 10 mL of aqueous extract to this mixture, stirring for 2 h at 65℃, centrifuging the product, and subjecting the product in hot oven at 39℃ for 4 h.
