This study reported synthesis of carbon foam from lignin–resorcinol–glyoxal (LRG) resin as carbon source and polyurethane (PU) foam as sacrificial template for effective removal of oils and organic solvents from water. The carbon foam with large surface area and high porosity was fabricated by carbonization of resin impregnated PU foam. The carbon foam can effectively absorb various oil or organic solvents from the aqueous media due to hydrophobic nature. Also, it can be recycled by completely burning the oil or organic solvents without destroying the foam structure. The carbon foam with high absorption capacity and good recyclability properties in the present work suggests promising applications in removal of oils and organic solvent spill from water.

In this study, a new plasmonic hybrid AgNSs@PANI/3D-CF composed of interlaced silver nanosheets (AgNSs) grown on polyaniline (PANI) nanobars decorated three dimensional macroporous carbon foam (3D-CF) was prepared for molecule sensing by surface enhanced Raman scattering (SERS). The morphology, component, adsorption ability and SERS activity of the hybrid were characterized by SEM, EDS, FTIR, XRD, UV–vis absorption spectrum, and Raman spectroscopy. Controlling the silver growth time and introduction of succinic acid are vital to obtain the interlaced silver nanosheets fully covered 3D scaffold. The porous structure and large surface area of the hybrid bring it a high adsorption ability to dye molecules. And interlaced AgNSs endow the hybrid with dense hot-spots for highly efficient SERS detection. The lowest SERS detectable concentration of 4-mercaptobenzoic acid (4-MBA), Nile blue (NB) and Methylene blue (MB) on AgNSs@PANI/3D-CF was 0.1 nM, 0.1 nM and 10 nM, respectively. A good result was also achieved for NB detection in real water sample. The proposed hybrid with unique structure, high Raman enhancement ability and good reproducibility may find promising applications in environment monitoring, optical sensing and so on.

Highly conductive and elastic three-dimensional (3D) porous carbon materials are ideal platforms to fabricate electrodes for high-performance compressible supercapacitors. Herein, a robust, highly conductive, and elastic carbon foam (CF) hybrid material is reported, which is fabricated by integrating cellulose nanofiber/multiwalled carbon nanotube (CNF/MWCNT) aerogel sheets with a melamine sponge (MS), followed by carbonization. The carbonized CNF/MWCNT aerogel sheets contribute to the high conductivity and specific surface area of the CF, and the 3D network-like skeleton derived from the carbonization of the MS enhances the elasticity and stability of the CF. More importantly, the CF possesses good scalability, allowing the introduction of electroactive materials such as polypyrrole (PPy) and Fe3O4 to fabricate high-performance compressible PPy–CF and Fe3O4–CF electrodes. Moreover, an assembled PPy–CF//Fe3O4–CF device shows reversible charging–discharging at a voltage of 1.6 V and demonstrates a high specific capacitance (172.5 F/g) and an outstanding energy density (59.9 W h/kg). The device exhibits capacitance retention rates reaching 98.3% and stable energy storage characteristics even under different degrees of compressive deformation. This study offers a scalable strategy for fabricating high-performance compressible supercapacitors, thereby providing a new means of satisfying the energy storage needs of portable electronic devices that are prone to deformation.

Polyethylene glycol (PEG)/hybrid carbon foam (CF) phase change materials (PCMs) were prepared by integrating PEG into CF via dynamic-vacuum impregnation. The hybrid CF was first synthesized by mixtures of graphene oxide (GO) and carbon nanotubes (CNTs) with different volume ratios. The morphologies, chemical structures, thermal conductivities, shape-stabilization levels, and photo-thermal energy conversion levels of these composite PCMs were characterized systematically. The prepared composite PCMs exhibited good shape-stabilization levels and showed their original shapes without any PEG leakage. It was found that the polyethylene glycol/carbon foam with multi-walled carbon nanotubes (PEG/MCF) composite PCMs had a better shape-stable performance below the temperature of 250 °C, and the thermal conductivity of the PEG/MCF composite PCMs reached as high as 1.535 W/(mK), which was obviously higher than that of polyethylene glycol/carbon foam with single-walled carbon nanotubes (PEG/SCF, 1.159 W/(mK)). The results of the photo-thermal simulation tests showed that the composite PCMs had the ability to absorb light energy and then convert it to thermal energy, and the maximum thermal energy storage efficiency of the PEG/MCF composite PCMs and the PEG/SCF composite PCMs was 92.1% and 90.6%, respectively. It was considered that a valuable technique to produce high-performance composite PCMs was developed.Keywords:polyethylene glycol;hybrid carbon foam;phase change;thermal energy storage

Functional form-stable phase change materials (FPCMs) offer great promise for thermal management in transport packaging due to their stability after phase change cycle and the extension of service life. However, challenges remain in enhancing thermal conductivity and energy storage efficiencies. In this study, a magnetically aligned h-BN-embedded superporous carbon foam-based FPCM containing paraffin (M-BN-CPCMs) was fabricated via a foam polymerization method followed by high-temperature carbonization. A super-porous hydrogel (SPH) precursor was used to construct a robust, highly porous carbon skeleton to accommodate more PCMs. To further enhance thermal conductivity, h-BN was functionalized with Fe 3 O 4 nanoparticles, and the resulting BN-Fe 3 O 4 was magnetically oriented within the carbon skeleton using a synchronous magnetization process. This novel design achieved a thermal conductivity improvement of over 90% compared to SPH. Additionally, the synergistic photothermal conversion effect achieved by the magnetic nanoparticles and carbon skeleton resulted in an outstanding photothermal conversion efficiency of approximately 90% for M-BN-CPCMs. Notably, the incorporation of BN-Fe 3 O 4 increased pore sizes, enabling higher paraffin loading capacity. The M-BN-CPCMs with large holes exhibit a remarkable phase change enthalpy of 154.9 J/g, demonstrating excellent energy storage capability, which surpasses that of superporous carbon foam skeleton-based FPCMs (CPCMs). The optimized M-BN-CPCMs demonstrated superior thermal energy storage, faster thermal charging rates, and improved thermal regulation, effectively reducing temperature fluctuations within insulated packaging. These findings underscore the potential of M-BN-CPCMs as a groundbreaking solution for energy storage and thermal management in transport packaging, addressing critical challenges in the field.

With the rapid advancement of communication technology, electromagnetic pollution has become a critical issue, driving the demand for lightweight, broadband, and efficient electromagnetic wave (EMW) absorption materials. However, achieving effective low-frequency EMW absorption remains challenging due to the trade-off between attenuation capability and impedance matching. Here, we report a novel MoS 2 /CNT carbon foam (MC@CF) derived from pyrolyzed polyimide composite foam integrated with hydrothermally synthesized MoS 2 /CNT. By precisely controlling the 1T-phase content and leveraging the 3D interconnected porous architecture and heterogeneous interfaces, improved impedance matching and enhanced EMW dissipation are achieved. The MC@CF demonstrates exceptional low-frequency absorption, with a minimum reflection loss (RL min ) of −65.6 dB in the C band and −49.4 dB at 2.25 GHz in the S band. Additionally, the foam exhibits a remarkable radar cross-section (RCS) reduction of 26.1 dB·m 2 , high compressive strength (1.45 MPa), and superior thermal insulation, making it promising for extreme environment applications.

Reports on shaped porous biochar adsorbents prepared with waste biomass by co-regulation of hydrophobicity, physical structure, and chemical properties to capture air pollutants are limited. This study utilized chitin, the main component of shrimp shell waste, as the raw material to explore the formation mechanism of carbonized porous hydrochars (CPHCs), adsorption performance, and mechanisms of para-xylene (PX) onto CPHCs. The optimal preparation conditions were determined as follows: 1.68 mL of H 2 SO 4 , 0.84 mL of H 3 PO 4 (H 3 PO 4 :H 2 SO 4 = 1:2, with a total acid volume of 2.50 mL), 12.50 g of phenol, liquefaction temperature of 150 °C, liquefaction time of 2 h, 5.20 g of NaOH, hydrothermal time of 12 h, hydrothermal temperature of 130 °C, a mixture ratio of 1:2.4 for chitin powder and ZnCl 2 , and a calcination temperature of 500 °C. The resulting CPHCs exhibited uniform size, high mechanical strength, and abundant micropores. The BET specific surface area, total pore volume, micropore volume, and water contact angle of CPHCs were 751.81 m 2 /g, 0.32 cm 3 /g, 0.16 cm 3 /g, and 120°, respectively. The adsorption of PX followed pseudo-first-order kinetics and Langmuir isotherm model, with a maximum adsorption capacity of 302.11 mg/g. The adsorption process was endothermic and spontaneous. The main mechanisms of PX adsorption on CPHCs involved hydrogen bonding, π-π interactions, and micro-pore filling. The preparation of shaped hydrophobic biomass materials using chitin powder is feasible, and CPHCs exhibited excellent capture performance for PX.

Red phosphorus (RP), as one of the most promising anode materials for lithium-ion batteries, attracts much attention for its high theoretical specific capacity, cost-effective, and commercial availability. However, poor cycling stability and rate capability caused by huge volume expansion and low intrinsic electronic conductivity hinder the commercialization of RP-based anode. Herein, RP confined in ultrathin hollow carbon-bubble-constructed foam (RP-HC) is developed to improve electronic conductivity and mechanical structure stability. Additionally, low-temperature atomic layer deposition (LT-ALD) technology is adopted to further modify the surface of the RP-HC, forming a core–shell RP-HC@TiO 2 structure with about 5 nm TiO 2 coating layer. Benefiting from the dual confinement of TiO 2 buffer layer and conductive porous carbon host with effective P O C bond, the RP-HC(70%)@TiO 2 electrode delivers an outstanding cycling performance (795.2 mAh g −1 after 200 cycles at 100 mA g −1 ) and rate capability (459.9 mAh g −1 at 2000 mA g −1 , almost 1.6 times and 12 times relative to RP-HC(70%) and RP under the same test condition). In-situ electrochemical impedance spectroscopy analyses are also conducted to investigate the superior Li + storage properties of the RP-HC@TiO 2 .

The adsorption and recovery of crude-oil from oily water using oil-selective adsorbents is a highly promising solution for the increasing worldwide oil pollution, but remain a challenge. Herein, we reported a carbon foam (CF) with switchable wettability as smart materials for fast oil adsorption and recovery. By grafting poly(4-vinylpyridine) (P4VP) onto the surface of CF, the obtained smart foam presented a pH responsiveness and could change superhydrophilic and superhydrophobic surface according to the pH value. Thus, the smart responsive carbon foam could fast adsorb the oil in neutral solution (pH = 7) with high oil adsorption capacity of 62–120 g g −1 and desorb all the adsorbed oil in acidic solution (pH = 1) within 1.5 min. In addition, only 3% loss was observed for oil (chloroform) adsorption and recovery after successive reuses of up to 15 cycles, which demonstrated great recyclability of the materials.

Development of low-cost equipment that can store clean energy, such as solar energy, is effective for alleviating environmental pollution. In this study, the shape-stabilized composite phase change materials (PCMs) based on paraffin wax and carbon foam were prepared. The carbon foam prepared from melamine foam had a good pore structure and was used to encapsulate paraffin wax. The latent heat of melting and cooling of composite PCMs were 221.1 J/g and 213.7 J/g, respectively. Even after 100 cycles, it still showed good thermal performance. Meanwhile, the composite PCMs exhibited good light-to-heat conversion efficiencies of 53.94% and 67.43% at light intensities of 200 mW cm −2 and 300 mW cm −2 , respectively. Overall, composite PCMs with excellent thermal performance and cycle stability have application prospects in industries such as construction, solar energy, and battery temperature-control systems.

Functional groups on carbon substrates help to anchor conductive polymers through electrostatic interactions, but excessive groups are usually contradictory to the improvement of graphitization, which is closely relevant to the conductivity of electrodes. Herein, the balance between graphitization and oxygen-containing functional groups of carbon substrates was analyzed via adjusting the carbonization temperature ( T c ) of carbon foams (CFs) and fabricating polypyrrole (PPy)/CFs free-standing electrodes. The graphitization of CFs is accompanied by the dissociation, migration and rearrangement of O atoms, resulting in structural changes of CFs at different T c , which affects the morphology of PPy, as well as the adsorption and electron transfer between CFs and PPy. Besides, the increase of T c improves the conductivity and rate capability of composite electrodes due to the graphitization enhancement of CFs. However, the accompanied reduction of functional groups results in the densification of PPy coatings, which causes the attenuation of specific capacitance and cycling stability of composite electrodes. In addition, PPy/CFs can show much better electrochemical performances than that of the pure PPy film, with a specific capacitance of 545.5F g −1 (1 A/g) and a 100% capacitance retention after 10,000 GCD cycles.

The catalytic oxidation of biomass-derived 5-hydroxymethylfurfural (HMF) to prepare 2,5-furandicarboxylic acid (FDCA) is a promising route to produce biomass-based functional materials. It is significant to develop non-noble metal-based catalysts for efficient conversion of HMF to FDCA. In this study, a facile and green technology was developed to prepare hierarchical porous carbon foam (CF)-supported MnO 2 (MnO 2 /CF) catalyst by in-situ growth of MnO 2 nanoparticles on blocky CF, and the catalytic activity of MnO 2 /CF for the oxidation of HMF to FDCA was evaluated. Under mild reaction conditions, the MnO 2 /CF catalyst achieved 99.8% conversion of HMF and 97.0% yield of FDCA, which was well beyond the catalytic performance of single MnO 2 . The results indicated that the CF with hierarchical porous structure and oxygen-containing groups could facilitate the diffusion of reactant molecules and regulate the crystal structure and morphology of MnO 2 . The synergistic interaction of CF and MnO 2 effectively enhanced specific surface area, surface acid-base sites, oxygen vacancy concentration, and charge transfer efficiency of MnO 2 /CF composite, contributing to favorable catalytic performance. Additionally, the MnO 2 /CF catalyst showed promising stability and reusability. This work provides new insights into the development of efficient, stable, and economical non-noble metal-based catalysts for catalytic conversion of biomass-based chemicals.
