Abstract

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. • Physico-chemical properties of CFP have led to their large-scale acceptance. • Nanostructured surface engineering ameliorates the catalytic activity of bare CFP. • Modified CFP can be utilized as an exceptional electrode for various electrochemical applications. • Evaluation of various surface modulations and applications of CFP towards electrocatalysis have been discussed.
