Research on status quo of global graphene technology based on bibliometrics

Innography patent database and Web of Science paper database are used to study the patent layouts and paper output results of global graphene technology,and the basic research and application research status of global graphene technology in recent five years are mainly analyzed.The research shows that China,the United States,Korea,Japan and India are the major graphene research and development(RD) countries;Chinese Academy of Sciences,Indian Institute of Technology,Tsinghua University,Samsung Electronics,LG Chem,and BOE are the main graphene RD institutions.Potential cooperative or competitive relationships exist between Chinese Academy of Sciences and Tsinghua University,and between Samsung Electronics and IBM,Semiconductor Energy Laboratory,the University of California,respectively.In addition,global graphene technology mainly focuses on graphene oxide,photocatalysis,hydrogen evolution reaction,adsorption,electrocatalysis,graphene electrode batteries,graphene electronic components,graphene preparation,etc.,and the pace of graphene industrialization is accelerating.
