Abstract
In this study, gold nanoparticles were supported at graphene derivatives (AuNPs@GDs) from chloroauric acid and graphene oxide (GO) by using sodium citrate, L-ascorbic acid, and 4-(2-hydroxyethyl)-1-piperazineethane-sulfonic acid (HEPES) as green reductants to evaluate the catalytic activity in the 4-nitrophenol (4-NP) reduction system. Among the three reductants, HEPES which derived AuNP@GD (3) exhibited up to 8.44-fold higher catalytic activity...
