Gold-graphene oxide nanohybrids: A review on their chemical catalysis
Muhammad Nur Iman Amir,Ahmed Halilu,Nurhidayatullaili Muhd Julkapli,Azman Ma’amor 한국공업화학회 2020 Journal of Industrial and Engineering Chemistry Vol.83 No.-
The discovery of graphene oxide (GO) has motivated enormous applications of gold (Au) nanoparticles(NPs) in catalysis due to its ability to function as a suitable catalyst support material. This reviewdiscussed the routes for AuNPs-GO synthesis such as chemical vapor deposition (CVD), electrochemical,sol-gel and hydrothermal methods as it pertains to chemical synthesis. Accordingly, the CVD approachhas the capability of producing a single layer of well-distributed AuNPs over GO to form a nanohybridframework. Although the common application of AuNPs-GO nanohybrids has been in nanosensors,recent reports showed its aptitude in chemical synthesis through hydrogenation and oxidation reactionsinvolving organic molecules. Therefore, due to the existing attributes of AuNPs catalysis, recommen-dations were suggested to guide its usage in the form of AuNPs-GO nanohybrids as a catalyst for specialtychemical production. This report should inspire future use of AuNPs-GO in the industrial catalyticsynthesis of various pharmaceuticals and energy-based platform organic molecules.
