“…Their Raman spectra (Figure 1c) show peaks at ca . 1350 and 1600 cm −1 corresponding to the characteristic D and G bands, respectively, of graphitic carbon materials [32] . While the G‐band is indicative of the presence of graphitic structure, the D‐band reveals the presence of disordered graphite sheets and/or amorphous carbon structure in the materials [33] .…”

In this work, nanoporous, heteroatom-doped carbon materials with tailorable structures and excellent charge/energy storage properties are synthesized using casein (a phosphoprotein) as a precursor and silica gel as a template via a facile synthetic route. The synthesis involves carbonization and etching. In the synthesis, an appreciable amount of the N and P atoms in casein make it as dopants into the nanoporous carbons, enabling the materials to efficiently store charge. The structures and compositions as well as the overall charge storage properties of the materials are easily tuned by varying the relative amount of silica gel template used with casein in the precursors. By using an optimal amount of silica in the casein/ silica self-assemblies, a nanoporous carbon with low resistance to Faradaic processes and good capacitance and pseudocapacitance is obtained. This material gives a capacitance of ca. 261 F g À 1 at 1 A g À 1 , which is higher than those of many recently reported carbon materials in the literature. Moreover, the material retains 95 % of the initial capacitance with ca. 100 % of coulombic efficiency after 10,000 charge-discharge cycles.

Graphic abstract Polyacrylonitrile (PAN)-based carbon precursor is a well-established and researched material for electrodes in energy storage applications due to its good physical properties and excellent electrochemical performance. However, in the fight of preserving the environment and pioneering renewable energy sources, environmentally sustainable carbon precursors with superior electrochemical performance are needed. Therefore, bio-based materials are excellent candidates to replace PAN as a carbon precursor. Depending on the design requirement (e.g. carbon morphology, doping level, specific surface area, pore size and volume, and electrochemical performance), the appropriate selection of carbon precursors can be made from a variety of biomass and biowaste materials. This review provides a summary and discussion on the preparation and characterization of the emerging and recent bio-based carbon precursors that can be used as electrodes in energy storage applications. The review is outlined based on the morphology of nanostructures and the precursor’s type. Furthermore, the review discusses and summarizes the excellent electrochemical performance of these recent carbon precursors in storage energy applications. Finally, a summary and outlook are also given. All this together portrays the promising role of bio-based carbon electrodes in energy storage applications.
