The frequent leakage of crude oil and the illegal discharge of industrial organic pollutants have caused serious damage to the ecological environment and the loss of valuable resources. In this paper, we introduce a sponge with magnetic and photothermal properties. Polydopamine and ferric oxide (Fe 3 O 4 ) were grafted onto the sponge, self-assembled on the three-dimensional (3D) skeleton surface by Zif material, and grafted with cetyltrimethoxysilane to make the modified sponge highly hydrophobic (water contact angle = 155°). Moreover, due to the dual photothermal conversion properties of polydopamine and ferric oxide (Fe 3 O 4 ), the modified sponge can be quickly heated to 110 °C under light (1.25 kw/m 2 ). The modified sponge demonstrated excellent crude oil adsorption capacity (44 g/g) and recyclability. Due to its magnetic properties (saturated magnetization = 4.43 emu/g), derived from the incorporation of Fe₃O₄, the sponge could be remotely controlled for adsorption. Moreover, it demonstrated the ability to continuously adsorb and collect light oil from the water surface with the aid of a peristaltic pump. The sponge also functioned as an efficient filter for separating heavy oil underwater through liquid gravity, achieving a separation efficiency of 97.2%. Therefore, this composite sponge not only presents a promising solution for crude oil spill remediation but also holds significant potential for industrial wastewater treatment, making it highly relevant for practical environmental applications.

Upgrading the most difficult-to-recycle waste polyvinyl chloride remains a significant challenge due to the potential formation of highly toxic substances, such as polychlorinated biphenyls. Here, we introduce a paradigm shift with a mild photothermal dechlorination–carbonization process that converts waste polyvinyl chloride plastics into valuable carbon materials. Through detailed techno-economic assessment (TEA) process modeling, based on recycling 96,000 tons of plastics, we demonstrate that utilizing clean solar energy for photothermal conversion can save approximately 2.34 × 1012 kJ electricity and reduce the carbon footprint by 261,912.2 tons compared to traditional thermal-driven methods, offering clear environmental benefits. Notably, this photothermal recycling method can process more than 10 types of postconsumer and mixed waste polyvinyl chloride plastics, yielding carbon materials that exhibit excellent performance as components in sodium-ion energy storage batteries. Photothermal catalytic recycling of plastics thus emerges as a green and sustainable technology with promising applications.

Uncontrolled antibacterial, insufficient barrier and low strength are the bottlenecks of food packaging applications. Herein, Ta 4 C 3 T x nanosheet as a template was used to prepare Ta 4 C 3 T x immobilized silver nanoparticles (Ta 4 C 3 T x -AgNPs), which was compounded with nanocellulose to obtain high-strength and high barrier controllable bactericidal nanocellulose-based bioplastic packaging (CTa-Ag). The results indicated that due to the hydrogen bonding between nanocellulose and Ta 4 C 3 T x , the bridging effect of QCS (quaternized chitosan) and the filling of Ta 4 C 3 T x -AgNPs, the CTa-Ag had tightly stacked microstructure, which endowed them with excellent mechanical properties (4.0 GPa), ultra-low oxygen permeability (0.009 cm 3 /m 2 ·d·atm) and stable photothermal conversion efficiency. Importantly, the packaging exhibits the ability to control the release of antibacterial active ingredients. Moreover, the synergistic effects of controllable release of nano active factors, photothermal and photocatalysis in CTa-Ag gave it long-lasting antibacterial properties . This study brings new insights into the design and manufacture of multifunctional, controllable and long-lasting antibacterial bioplastic food packaging.

Phosphorus-modified hexadecanol is regarded as a promising heat storage medium for form-stable phase-change materials (FSPCMs) because of its high energy storage density and good thermal stability . In this study, a novel FSPCM was fabricated using phosphorus-modified hexadecanol, 1-oxo-4-hydroxymethyl-2,6,7-trioxa-l-phosphabicyclo [2.2.2] octane (PEPA), and pentaerythritol (PER). Among all the samples, FSPCM (P3), containing 9 % PEPA and 3 % PER, exhibited the optimal thermal storage performance and flame-retardant properties. Its latent heat was 122.5 J/g, and its photo-to-heat conversion efficiency was 61.8 %. The limiting oxygen index of P3 approached 29.5 %, and the UL-94 V -0 rating was attained. The decomposition and fire-retardant mechanism were inferred based on the analysis of char residues and the gaseous phase to determine the interaction between the PCMs and flame retardants.

Photothermal conversion efficiency (PCE) plays a crucial role in tumor photothermal therapy (PTT). In this work, we developed a MoS 2 -based antitumor agent with enhanced photothermal conversion efficiency by size/morphology tailoring and IR820 loading for combinational photothermal/photodynamic therapy (PTT/PDT) of breast cancer. Among three MoS 2 -based nanomaterials, namely MoS 2 nanospheres (NSs), MoS 2 nanoflowers (NFs) and MoS 2 quantum dots (QDs), MoS 2 NSs possessed the highest PCE at 37.48%. In order to further improve the PCE, polyethyleneimine (PEI)-assisted photosensitizer IR820 decoration was carried out to prepare the MoS 2 @PEI@IR820 (MPI) nanocomposite. The introduced IR820 not only improves PCE of the MoS 2 nanomaterials to 47.08% by increasing the light absorption for enhancing PTT, but produces cytotoxic ROS for PDT, resulting in a combinational PTT/PDT with the multifunctional MPI. In addition, in vivo fluorescence (FL) bioimaging and infrared thermographic imaging have been achieved by the designed MPI nanoplatform, which has proven to be good biocompatibility, low toxicity and high PCE. This study provides a novel way for the design and construction of prominent theragnostic nanoagents for combinational PTT/PDT.

Antibiotics are crucial for treating and preventing bacterial infections. However, the widespread use of antibiotics has led to serious antibiotic resistance issues. To address the growing threat of antibiotic-resistant bacterial infections, we designed and synthesized an antibacterial composite material, CCM@ZIF-8@PDA, through a one-pot method and surface modification strategy. This material combines the antibacterial properties of the natural product curcumin, the advantages of ZIF-8, and the photothermal conversion capability of PDA. It exhibits three antibacterial mechanisms against S. aureus: chemical antibacterial, ionic antibacterial, and photothermal antibacterial effects. At a low concentration of 100 ppm, CCM@ZIF-8@PDA achieves a 100% antibacterial rate. This multi-modal antibacterial strategy provides insights for developing new antibacterial materials to combat antibiotic resistance.

Due to its high porosity, large specific surface area, and strong photothermal conversion performance, graphene aerogel has unique advantages in the field of pollution treatment, especially in the field of recovering highly viscous oils. However, for the treatment of highly viscous oils, the high adsorption capacity and high adsorption rate of graphene aerogel often cannot be combined, which is one of the important reasons limiting its development in this field. A double-step templating strategy for graphene aerogels preparation was used in this work, i.e., Pickering emulsion soft templating and unidirectional freeze casting. Specifically, the dense Pickering emulsion droplets can be stabilized in a short period of time, so that they can be cured quickly. After that, graphene aerogels (DGA-0.8-25) with dual pore structure were prepared by unidirectional freeze casting technology to further form aligned pores based on the pores formed by the Pickering emulsion droplet soft template. The dense presence of Pickering emulsion droplets gives DGA-0.8-25 an ultra-high porosity (96.8 %), which can adsorb 184.53 times its own mass of crude oil. Due to the unidirectional pore structure, the adsorption rate of DGA-0.8-25 on crude oil is as high as 8.39 g·g −1 ·min −1 , which realizes dual improvement of the adsorption capacity and rate of graphene aerogel on crude oil and shows a good application prospect in the treatment of high viscosity crude oil. In addition, DGA-0.8-25 has unique advantages in the field of oil–water separation, with a separation efficiency of 99.04 % for water-in-oil emulsions and 97.63 % for oil-in-water emulsions. When repeated used in photothermal adsorption of highly viscous oil, DGA-0.8-25 can still maintain more than 90.61 % of its initial adsorption capacity after ten cycles of use-regeneration. Because of its unique advantages such as high efficiency and low cost, DGA shows promising in its future large-scale use.

With the improvement in people’s living standards, the development and application of smart textiles are receiving increasing attention. In this study, a carbon nanosurface was successfully coated with a SiO2layer to form C@SiO2nanomaterials, which improved the dispersion of carbon nanomaterials in an aqueous solution and enhanced the absorption of light by the carbon nanoparticles. C@SiO2nanoparticles were coupled on the surface of silk fabric with the silane coupling agent KH570 to form C@SiO2nanosilk fabric. The silk fabric that was subjected to such surface modification was endowed with a special photothermal function. The results obtained with scanning electron microscopy (SEM), energy dispersive spectrometer (EDS), and infrared spectroscopy (FTIR) showed that C@SiO2nanoparticles were successfully modified on the surface of the silk fabric. In addition, under the irradiation of near-infrared light with a power of 20 W and a wavelength of 808 nm, the C@SiO2nanosilk fabric experienced rapid warming from 23 °C to 60 °C within 30 s. After subjecting the functional fabric to hundreds of photothermal experiments and multiple washes, the photothermal efficiency remained largely unchanged and proved to be durable and stable. In addition, the thermogravimetric (TG) analysis results showed that the C@SiO2nanoparticles contributed to the thermal stability of the silk fabric. The UV transmittance results indicated that C@SiO2nanofabric is UV-resistant. The silk modification method developed in this study is low-cost, efficient, and environmentally friendly. It has some prospects for future applications in the textile industry.

In recent years, freshwater resources have become a global concern, and solar vapor generation (SVG) has garnered significant attention from researchers. Herein, a novel hydrogel solar evaporator was prepared by incorporating lignin and CuS-rGO into a chitosan-gelatin matrix. The anisotropic and isotropic morphologies of the hydrogel were prepared by pathway control on the solidification velocities of ice crystals and ice seeds. It presented that the anisotropic morphology can improve the refraction of light and increase the utilization rate of light by forming a light trap, leading to higher water evaporation rate . Additionally, ice seed was introduced during the freezing process, producing an anisotropic hydrogel with curled layer structure that endowed lower enthalpy of water evaporation and faster water transfer rate, resulting in high evaporate of 3.62 kg m −2 h −1 under one solar irradiation with photothermal conversion efficiency of 97.7 %. Finally, the gel also demonstrated good mechanical properties , long-term working stability and harsh environment tolerance, which make it ideal for outdoor applications. The hydrogel evaporator had potential to generate 25.24 kg m 2 water per day that could meet the huge demand for freshwater as sources.

4-Nitrophenol (4-NP) is one of the most difficult treated water pollutants in industrial wastewater . Herein, the silver nanoparticle/polydopamine (Ag-PDA/PDMS) composite is successfully prepared by in situ reducing Ag catalyst on PDA surface. The Ag-PDA/PDMS catalytic layer possesses an excellent light-to-heat conversion ability and stability under light irradiation. The degradation rate of 4-NP to 4-aminophenol (4-AP) under light irradiation is significantly higher than that of non-irradiation, resulting from both the temperature rise in the catalytic layer, and hot electrons produced by Ag nanoparticles. The temperature rise caused by the photothermal conversion of light-irradiated catalytic layer dominates the performance improvement. The degradation rate of 4-NP reaches 95 % under light irradiation, demonstrating an efficient pathway to design the robust catalyst composites with high-performance photothermal conversion efficiency.

Developing multifunctional and super-wetting separation materials is of great significance for treating complex oily wastewater in real environment. Herein, the superhydrophilic Cu-HHTP@Cu foam with hierarchical structure was fabricated by chemical oxidation and in situ growth strategies, which showed an outstanding separation efficiency (>99.4 %) and flux (>92.1 kL∙m −2 ∙h −1 ) for various oil/water mixtures. The electrostatic attraction, π − π interactions and hydrogen bonding between Cu-HHTP@Cu foam and dyes facilitate the adsorption process, with a removal efficiency > 94.7 %. To absorb high-viscosity crude oil, the Cu-HHTP@Cu foam was further modified with polydimethylsiloxane (PDMS) to finally obtain superhydrophobic PDMS@Cu-HHTP@Cu foam, which demonstrates high separation efficiency (>99.8 %) and flux (>90.3 kL∙m −2 ∙h −1 ). Both Cu-HHTP@Cu foam and PDMS@Cu-HHTP@Cu foam also showed stable durability after 20-cycle tests. More importantly, due to the introduction of Cu-HHTP, PDMS@Cu-HHTP@Cu foam presented excellent photothermal conversion behavior with the surface temperature reaching up to 72.0℃ under simulated sunlight, which remarkably facilitate the cleaning of crude oil. This work shows that modified Cu foam is a promising candidate for absorbing dyes and treating crude oil spills and is expected to provide a convenient method for oil/water separation.

Green, efficient treatment of crude oil spills and oil pollutants is a global challenge, with adsorption technology favored for its efficiency and low environmental impact. The development of an environmentally friendly adsorbent with high hydrophobicity, excellent adsorption performance, and degradability is crucial to overcoming the limitations of petroleum-based adsorbents. Here, a lignin-based polyurethane foam (LPUF) with superhydrophobic and photothermal oil-absorbing properties was fabricated by incorporating octadecyltrimethoxysilane into the foam system. The modified foam showed a 151.4° water contact angle, as long-chain alkyl groups reduced surface energy, giving it superhydrophobicity. The foam adsorbent exhibited remarkable adsorption performance for a variety of organic solvents, achieving a maximum adsorption capacity of 20 g g−1 and an oil–water separation efficiency exceeding 97%. Due to its outstanding elastic recovery properties, the foam exhibited only a 1.5% reduction in adsorption capacity after 10 adsorption–desorption cycles, indicating its strong potential for repeated adsorption and recovery. Under 1 kW m−2 sunlight intensity, the surface temperature of the foam adsorbent rose to 79.7 °C within 350 seconds. The excellent photothermal conversion properties of the foam significantly reduced the viscosity of the surface crude oil, thereby increasing the adsorption rate. In addition, the modified foam adsorbent also demonstrated self-cleaning properties and could be completely degraded after 5 hours of treatment in an alkaline solution. The developed LPUF adsorbent exhibited superior hydrophobicity and oil–water separation capabilities, highlighting its potential for efficient oil pollutant removal, while also offering new avenues for the high-value utilization of renewable resources.
