“…This is nearly equivalent to the photothermal conversion efficiency of a recently reported carbon-based material with exceptionally high photothermal performance. 80 Table 4 compares the results of this work with the outcomes of related researches aimed at improving photothermal performance in recent years. It can be observed that previous efforts have primarily focused on enhancing photothermal performance through the development of novel composite materials or altering material components or structures, yet the improvements have always been limited.…”

“…Amylopectin is widely found in various biomass starches and is a widely available, inexpensive, and highly abundant biomass material. It has excellent adhesion and forming effects and is an ideal source material for biomass-derived carbon aerogel [35][36][37]. The specific preparation steps [38,39]: First, the ceramic fibers were crosslinked by high-speed stirring in an homogenizer (T18 digital ULTRA-TURRAX, IKA, Baden-Württemberg, Germany) with different mass ratios in the starch solution containing ammonium persulfate and N,N-methylenebisacrylamide.…”

The use of solar interface evaporation for seawater desalination or sewage treatment is an environmentally friendly and sustainable approach; however, achieving efficient solar energy utilization and ensuring the long-term stability of the evaporation devices are two major challenges for practical application. To address these issues, we developed a novel ceramic fiber@bioderived carbon composite aerogel with a continuous through-hole structure via electrospinning and freeze-casting methods. Specifically, an aerogel was prepared by incorporating perovskite oxide (Ca0.25La0.5Dy0.25)CrO3 ceramic fibers (CCFs) and amylopectin-derived carbon (ADC). The CCFs exhibited remarkable photothermal conversion efficiencies, and the ADC served as a connecting agent and imparted hydrophilicity to the aerogel due to its abundant oxygen-containing functional groups. After optimizing the composition and microstructure, the (Ca0.25La0.5Dy0.25)CrO3 ceramic fiber@biomass-derived carbon aerogel demonstrated remarkable properties, including efficient light absorption and rapid transport of water and solutes. Under 1 kW m−2 light intensity irradiation, this novel material exhibited a high temperature (48.3 °C), high evaporation rate (1.68 kg m−2 h−1), and impressive solar vapor conversion efficiency (91.6%). Moreover, it exhibited long-term stability in water evaporation even with highly concentrated salt solutions (25 wt%). Therefore, the (Ca0.25La0.5Dy0.25)CrO3 ceramic fiber@biomass-derived carbon aerogel holds great promise for various applications of solar interface evaporation.

To enhance the efficient utilization of waste hemp rods, a kind of three‐dimensional (3D), mesh‐like lamellar structured hemp‐based biomass carbon aerogel (CA) was developed by freeze‐drying and subsequent high‐temperature carbonization method. The microstructure, flame resistance, thermal stability, and thermal conductivity of CA were investigated using several analytical techniques, including scanning electron microscopy (SEM), Fourier‐transform infrared spectroscopy (FTIR), X‐ray diffraction (XRD), simulated combustion tests, and thermogravimetric analysis (TG). Optimum formulation yielded at an alkali treatment concentration of 20% and a carbonization temperature of 700°C, CA with a 3D network of reticulated lamellae was obtained. CA exhibited minimal values for thermal conductivity (0.06 W/m K) and thermal diffusion coefficient (0.41 mm2/s), which are indicative of superior insulative properties. Moreover, the material demonstrated remarkable thermal endurance and flame resistance, achieving a char yield of 70.03% when subjected to a temperature of 700°C in an oxidative environment.
