“…Additionally, g-C 3 N 4 was embedded onto conductive polymers as an efficient electrode material for supercapacitors to improve electrochemical and mechanical stability. [144][145][146] Yang and coworkers prepared a novel electrode material for supercapacitors composed of poly(3,4-ethylenedioxythiophene) (PEDOT):poly(styrenesulfonate) (PSS) and g-C 3 N 4 by the layer-by-layer assembly method. 147 Compared with pure PEDOT, the PEDOT/g-C 3 N 4 composite demonstrated excellent electrochemical stability in neutral electrolyte and enhanced electrochemical performance of capacitance of 137 F g À1 in H 2 SO 4 and 200 F g À1 in Na 2 SO 4 , respectively.…”

Researchers have recently focused on the advancement of new materials from bio-renewable and sustainable sources because of the great concerns about environmental, waste accumulation and destruction, and the inevitable depletion of fossil resources. The bio-renewable-based materials have been extensively used as a matrix or reinforcement in many applications. In the development of innovative methods and materials, composites offer important advantages because of their excellent properties such as ease of fabrication, higher mechanical properties, high thermal stability, and many more. Especially, the nanocomposites (obtained by using biorenewable sources) have significant advantages when compared to conventional composites.The nanocomposites have been utilized in many applications ranging from food, biomedical, electroanalysis, energy storage, wastewater treatment, automotive etc. This comprehensive review provides chemistry, structures, advanced applications and recent developments about nanocomposites obtained from bio-renewable sources.

Freestanding electrodes composed of 2D materials are highly attractive for many applications such as batteries, membranes, actuators, optical devices, and other energy-related devices owing to their low price, unique structure, high specific surface area, and excellent mechanical and electrical properties. Here, we report the facile large-scale fabrication of freestanding hierarchical carbon nitride/carbon electrodes (CN/C) by the in situ crystallization of CN precursors on conductive carbon paper, followed by thermal annealing. The resulting CN exhibits a vertically aligned morphology with a homogeneous layer distribution, improved crystallinity, and excellent contact with the carbon paper. The freestanding electrodes exhibit high electrical conductivity and good photoelectrochemical activity as anodes in water splitting photoelectrochemical cells. Furthermore, we show here as a proof-of-concept that the freestanding CN/C electrodes can be used as photoelectrocatalysts for the oxidative degradation of organic compounds in water, with enhanced activity compared to photocatalytic and electrocatalytic degradation, while the extracted electrons can be used for the simultaneous production of hydrogen at the cathode.
