Embodiment 1
[0025] Press Ru 3+ : PVP monomer molar ratio is 1:10, weigh a certain amount of RuCl 3 ·nH 2 O and PVP, fully dissolve them in 10 ml of n-propanol under ultrasound, pour the above mixed solution into a 50 ml round bottom flask, add a stirring bar, stir rapidly at room temperature in a water bath for 10 hours, the solution turns from brownish red to final Turned brown, that is, the reaction is complete. Mix the original solution with the precipitating agent acetone 1:3 and then centrifuge. After centrifuging at 8000 rpm for 5 minutes, take the precipitate and wash it with water. Repeatedly washing with acetone and deionized water for 3-5 times, the obtained precipitate is dissolved in water to become an aqueous solution of ruthenium nanoparticles.
[0026] Add 2 ml of 0.1 mol / L freshly prepared sodium borohydride solution and 10 μL of 10 -2 mol / liter prepared p-nitrophenol aqueous solution, and finally add a small amount of synthesized ruthenium nanoparticle aqueous solutio...
