Special Issue Information

Dear Colleagues,

Carbon aerogels were first developed in the 1980s as a variation of traditional aerogels, utilizing carbon-based precursors instead of silica or other materials. Carbon aerogels have garnered significant attention in numerous applications due to their unique properties, such as a low density, high surface area, and excellent electrical conductivity.

However, the synthesis of carbon aerogels often involves complex and energy-intensive processes, which have hindered their properties, scalability, and competitiveness in industrial applications. Exploring future sustainable materials and technologies to diversify the performance and applications of carbon aerogels is highly desirable, aiming to meet various demands in the industrial utilization of carbon aerogels.

Guided by the above vision, this Special Issue, titled the “Synthesis, Properties and Applications of Carbon Aerogel”, is dedicated to publishing novel theoretical and fundamental research focused on the design, synthesis, characterization, and applications of carbon aerogels. Potential topics for this Special Issue include, but are not limited to, the following:

  • Carbon precursor or carbon nanomaterials for producing new carbon aerogels;
  • Advanced or industrialized fabrication strategy;
  • Nano/microstructure design of carbon aerogels;
  • Carbon-aerogel-based nanocomposites;
  • Theoretical and fundamental analysis of carbon aerogel (physical, spectrum, analytical, density functional theory, etc.);
  • Carbon aerogels with high performance and advanced applications (electromagnetic wave shielding/absorption, electronics, catalysis, energy storage/conversion, optoelectronic, thermal application, biomedical, etc.).

We are pleased to invite you to submit details of your latest research work in any research field relevant to this Special Issue. Submissions of short communications, full research papers, and review papers are all welcomed.

We look forward to receiving your contributions.

The electro-Fenton process is based on the generation of hydroxyl radicals (OH•) from hydroxide peroxide (H2O2) generated in situ by an oxygen reduction reaction (ORR). Catalysts based on carbon gels have aroused the interest of researchers as ORR catalysts due to their textural, chemical and even electrical properties. In this work, we synthesized metal-free electrocatalysts based on carbon gels doped with graphene oxide, which were conformed to a working electrode. The catalysts were prepared from organic-gel-based inks using painted (brush) and screen-printed methods free of binders. These new methods of electrode preparation were compared with the conventional pasted method on graphite supports using a binder. All these materials were tested for the electro-Fenton degradation of amoxicillin using a homemade magnetite coated with carbon (Fe3O4/C) as a Fenton catalyst. All catalysts showed very good behavior, but the one prepared by ink painting (brush) was the best one. The degradation of amoxicillin was close to 90% under optimal conditions ([Fe3O4/C] = 100 mg L−1, −0.55 V) with the catalyst prepared using the painted method with a brush, which had 14.59 mA cm−2 as JK and a H2O2 electrogeneration close to 100% at the optimal voltage. These results show that carbon-gel-based electrocatalysts are not only very good at this type of application but can be adhered to graphite free of binders, thus enhancing all their catalytic properties.
