“…Therefore, the obtained carbon product has high SSA of 3837 m 2 g À1 and wide pore distribution. 184 MXenes are also used as templates for the synthesis of porous carbons owing to its rich surface terminations and two-dimensional morphology. Hu et al prepared MXene-coated carbon cloth from silk fabrics (Fig.…”

“…The ice-templating technique sustains the uniform dispersion of KOH with the tremella cells and avoids the aggregation of the cell walls by ice sublimation that can otherwise occur by conventional drying. 184 Chen et al fabricated wood-derived graphitized carbon aerogel through freeze-casting and carbonization processes, wherein ordered tracheid-like stable structure, high carbon content, SSA of 950.4 m 2 g À1 and wide range of pores were obtained (Fig. 9g).…”

“…The materials produced to provide high capacitance, fast response and high cycle number, especially in supercapacitor applications [34,35]. Especially the large surface area due to the porous structure of the carbon-based materials obtained and the ability to be made with an cost-effective and unlimited precursor provides a great advantage [34][35][36][37][38][39][40][41][42].…”

“…This is very important to obtain consistent activities from the contributed material. In one of these studies, Wu et al [41] reported that by using melamine foam it is possible to obtain hierarchical porous carbon. They used the waste liquid of the vitamin-C production as the precursor and obtained highly porous carbon by using this template.…”

Biomass is the general term for organic substances derived from living organisms (plants and animals). Since, biomass is a renewable, sustainable, innovative, low cost and carbon-neutral energy source, the applications of nano-micro particles produced from biomass in electrochemical applications have emerged. A large number of carbon-based materials, such as featured activated carbon, carbon nanotube, C-dots, biochar, hybrid carbon-metal/metal oxide … etc. can be produced from divergent types of biomass. With the growing energy need in the world, supercapacitors have also developed considerably besides the energy generation and storage methods. The supercapacitor is an energy storage system that can work reversibly to provide high energy in a short time. In these systems, electrode structure and surface properties are crucial for energy capacity enhancement. In this sense, electrode modifications with the above-mentioned biomass-based nano-micro structures are widely used in supercapacitor applications.

“…Studies have shown that highly graphitized carbon promotes the reduction of nitrobenzene by enhancing electron transfer 23 . Carbon materials have the advantages of flexibility for tailoring the pore structures and the potential for modification of the catalytic surface sites via introducing heteroatoms 24,25 . Up to now, there have been several developed methods to modify the properties of carbon materials via activation with varied regents or doping with nitrogen, sulfur, phosphorus, etc [26][27][28][29][30] .…”

Aniline is a group of important platform molecules and is widely used in the synthesis of other high-value chemicals and pharmaceutical products. How to produce high-value anilines as the high-value chemical intermediates more efficiently and more environmentally has always been a research topic in the industry. Catalytic hydrogenation is an environmentally friendly method for preparing halogenated anilines. Traditional noble metals catalysis face cost and noble metals residue problems. To improve the purity of the product and the activity and recyclability of the catalyst, we prepared a Pd/Fe magnetic bimetallic catalyst supported on N-doped carbon materials to reduce nitrobenzene to aniline under mild conditions. The loading of Pd was very low, which was 1/10 of the content of common commercial precious metal Pd/C and Pt/C catalysts, which was only 0.5%. And the prepared bimetallic Pd/Fe@N/C catalyst showed excellent catalytic reactivity with the conversion rate of nitrobenzene > 99%, and the selectivity of aniline 99% under mild reaction conditions of 0.8 MPa H2 and 40 °C. A variety of halogenated and aliphatic nitro compounds were well tolerated and had been transformed to the corresponding target amine products with excellent selectivity. In addition, the novel N-doped graphene-encapsulated bimetallic magnetic Pd/Fe@N/C catalyst not only had magnetic physical properties, which was easy to separate, recover, and used for the recycling of the catalyst without metal leaching but also catalyzed highly selective reductive amination of aromatics was a green, economical and environmentally friendly reaction with the only H2O as a by-product.
