“…Carbon materials, such as graphene, CNT, nanodiamonds, carbon fiber, and fullerenes, have attracted great interest in recent years [93,94,95,96,97,98,99,100,101,102,103,104,105,106,107]. In the past decades, carbon materials, particularly CNT and graphene, have been widely employed in the fabrication of thermoelectric materials because of the following reasons: (1) carbon materials have an intrinsically high electrical conductivity, which can significantly enhance the thermoelectric efficiency of thermoelectric materials; (2) as novel carbon nanomaterials, their large specific surface areas can promote the formation of a highly efficient interface between the polymer matrix and the carbon particles [93,108,109,110,111,112,113,114]; (3) the high thermal conductivity of carbon materials can be alleviated by wrapping or coating the polymer matrix on their surfaces [115]; and (4) carbon-based thermoelectric polymer composites are flexible, low-cost, and non-toxic, in addition to having high mechanical strength and being light-weight.…”

Thermoelectric devices have recently attracted considerable interest owing to their unique ability of converting heat to electrical energy in an environmentally efficient manner. These devices are promising as alternative power generators for harvesting electrical energy compared to conventional batteries. Inorganic crystalline semiconductors have dominated the thermoelectric material fields; however, their application has been restricted by their intrinsic high toxicity, fragility, and high cost. In contrast, organic thermoelectric materials with low cost, low thermal conductivity, easy processing, and good flexibility are more suitable for fabricating thermoelectric devices. In this review, we briefly introduce the parameters affecting the thermoelectric performance and summarize the most recently developed carbon-material-based organic thermoelectric composites along with their preparation technologies, thermoelectric performance, and future applications. In addition, the p- and n-type carbon nanotube conversion and existing challenges are discussed. This review can help researchers in elucidating the recent studies on carbon-based organic thermoelectric materials, thus inspiring them to develop more efficient thermoelectric devices.

Composite Fenton nanocatalyst was prepared by water-based in situ creation of Fe3O4 nanoparticles integrated within the self-assembly 3D reduced graphene oxide (rGO) aerogel. The hybrid applied for the degradation of Acid Green 25 (AG-25) organic dye in an aqueous solution, in the presence of H2O2. By investigating the conditions that maximize the dye adsorption by the 3D composite, it was found that the pH of the solution should be adjusted between the pKa of the functional groups present on the rGO surface (carboxylic acid) and that of the dye (sulfonic acid) to promote electrostatic interactions dye—3D structure. Performed under these conditions, Fenton degradation of AG-25 in presence of H2O2 was completed in less than 30 min, including all the intermediate products, as demonstrated by MALDI–TOF–MS analysis of the aqueous solution after discoloration. Moreover, this was achieved in a solution with as high a dye concentration of 0.5 mg/mL, with only 10 mg of 3D composite catalyst, at room temperature and without additional energy input. The high performance was attributed to the creation of charge-transfer complex between rGO and Fe3O4 nanoparticles throughout covalent bond C–O–Fe, the formation of which was promoted by the in situ synthesis procedure. For the first time, up to the authors’ knowledge, AG-25 degradation mechanism was proposed.
