▎ 摘  要

NOVELTY - Preparing nitrogen-doped graphene-Ag nanometer compound material comprises (i) adding graphite oxide into de-ionized water, ultrasonically dispersing until the solution is transparent to obtain graphene oxide dispersion, adding urea into ultrasonic solution, (ii) adding silver nitrate solution into the graphene oxide dispersion, continually ultrasonicating, adjusting the pH value to 10 to obtain mixture, and (iii) placing the mixture in reaction vessel for hydrothermal synthesis reaction, washing with deionized water to neutrality, and vacuum drying. USE - The nitrogen-doped alkene-Ag nano composite useful for catalytic reduction of p-nitroaniline (claimed). ADVANTAGE - The composite material has high catalyst dispersibility, catalytic activity and good stability.
