A road map on nanostructured surface tuning strategies of carbon fiber paper electrode: Enhanced electrocatalytic applications

Impressive characteristics of carbon fiber paper (CFP) electrodes propound greater demand in electrochemical applications. CFP has a network structure composed of interwoven carbon fibers (CFs). The macroporous structure, chemical inertness, high conductivity, low cost, corrosion resistance, good electrical properties, mechanical strength, and self-standing capabilities have led to the large-scale acceptance of CFP. This review appraises the current progress of CFP based electrodes for electrocatalytic applications in the field of electrochemical sensors, electrochemical capacitors, batteries, electro Fenton oxidation, electrooxidation of alcohols, water splitting, hydrogen evolution reaction (HER), and oxygen evolution reaction (OER) together with the different fabrication strategies on the CFP substrate in an organized manner. The different modifiers used for surface tuning of CFP addressed in this review are the conducting polymers, carbon-based nanomaterials, transition metal dichalcogenides/phosphides/carbides, and nanostructured metal oxides.
