The ascribed work suggests a fabrication pathway of carbon aerogel material from the rose apple (Syzygium jambos) fruit (RACA), in which a hydrothermal step, followed by a calcination process under various temperatures from 600 to 900 °C was carried out. RACA were characterized via multiple methods to briefly determine the optimal calcination temperature for the application, revealing that the temperature of 700 °C provided an intermediate deconstruction effect to form the amorphous structure and amplified the surface area. Whence, the materials were assessed for the adsorption capacities towards diesel oil which provided a capacity of approximately 35 g/g, although the adsorption capacity decreased slightly after 5 cycles of recovery and reuse. Furthermore, RACA‐700 exhibits high adsorption capacity of organic solvents (toluene, cyclohexane, butanol, hexane, and chloroform) and the ciprofloxacin antibiotic. Besides, the utilization of the fabricated carbon aerogel in the supercapacitor was also investigated. The obtained results elucidate the highest specific capacitance of 61.20 F/g, corresponding with the lowest resistance of 195.6 Ω, which indicates the ability to maintain capacitance after 5000 cycles and still retain 60 % efficiency, thereby signifying the potential application of carbon aerogel in sustainable material construction.

Abstract3D carbon‐based porous sponges are recognized for significant potential in oil absorption and electromagnetic interference (EMI). However, their widespread application is hindered by a common compromise between high performance and affordability of mass production. Herein, a novel approach is introduced that involves laser‐assisted micro‐zone heating melt‐blown spinning (LMHMS) to address this challenge by creating pitch‐based submicron carbon fibers (PSCFs) sponge with 3D interconnected structures. These structures bestow the resulting sponge exceptional characteristics including low density (≈20 mg cm−3), high porosity (≈99%), remarkable compressibility (80% maximum strain), and superior conductivity (≈628 S m−1). The resultant PSCF sponges realize an oil/organic solvent sorption capacity over 56 g/g and possess remarkable regenerated ability. In addition to their effectiveness in cleaning up oil/organic solvent spills, they also demonstrated strong electromagnetic shielding capabilities, with a total shielding effectiveness (SE) exceeding 60 dB across the X‐band GHz range. In virtue of extreme lightweight of ≈20 mg cm−3, the specific SE of the PSCF sponge reaches as high as ≈1466 dB cm3 g−1, surpassing the performance of numerous carbon‐based porous structures. Thus, the unique blend of properties renders these sponges promising for transforming strategies in addressing oil/organic solvent contaminations and providing effective protection against EMI.
