摘      要：Paper-based electrochemical sensors provide the opportunity for low-cost,portable and environmentally friendly single-use chemical analysis and there are various reports of surface-functionalized paper *** we report a composite paper electrode that is fabricated through designed papermaking using cellulose,carbon fibers(CF),and graphene oxide(GO).The composite paper has well-controlled structure,stable,and repeatable properties,and offers the electrocatalytic activities for sensitive and selective chemical *** demonstrate that this CF/GO/cellulose composite paper can be reduced electroche mically using relatively mild conditions and this GO reduction confers electrocatalytic properties to the composite ***,we demonstrate that this composite paper offers sensing performance(sensitivity and selectivity)comparable to,or better than,paperbased sensors prepared by small-batch surface-modification(e.g.,printing)*** envision this coupling of industrialized papermaking technologies with interfacial engineering and electrochemical reduction can provide a platform for single-use and portable chemical detection for a wide range of applications.
