“…Researchers have recently concentrated on developing phase change materials (PCMs) based on CNTs for use in solar water heating technologies in order to improve the thermal efficiency of solar water heaters [ 113 , 114 ]. Sobhansarbandi et al [ 115 ] enhanced the absorptivity of vacuum tube solar collectors (ETCs) for water heaters by employing “dry-drawable” CNT plate coatings.…”

Population growth and the current global weather patterns have heightened the need to optimize solar energy harvesting. Solar-powered water filtration, electricity generation, and water heating have gradually multiplied as viable sources of fresh water and power generation, especially for isolated places without access to water and energy. The unique thermal and optical characteristics of carbon nanotubes (CNTs) enable their use as efficient solar absorbers with enhanced overall photothermal conversion efficiency under varying solar light intensities. Due to their exceptional optical absorption efficiency, low cost, environmental friendliness, and natural carbon availability, CNTs have attracted intense scientific interest in the production of solar thermal systems. In this review study, we evaluated CNT-based water purification, thermoelectric generation, and water heating systems under varying solar levels of illumination, ranging from domestic applications to industrial usage. The use of CNT composites or multilayered structures is also reviewed in relation to solar heat absorber applications. An aerogel containing CNTs was able to ameliorate water filtering performance at low solar intensities. CNTs with a Fresnel lens improved thermoelectric output power at high solar intensity. Solar water heating devices utilizing a nanofluid composed of CNTs proved to be the most effective. In this review, we also aimed to identify the most relevant challenges and promising opportunities in relation to CNT-based solar thermal devices.

“…As the renewable energy industry continues to grow, our need for better, cheaper energy storage is also growing. − Lithium-ion batteries currently account for most of the global battery storage market, making them the most common type from portable electronics to electric vehicles. − However, the development of lithium-ion batteries also faces many problems, such as their relatively high cost and flammability problems if not properly managed . Aluminum is more abundant, safer, and more recyclable than lithium .…”

We report a low-cost, high theoretical specific capacity π-conjugated organic compound (PTCDA) with CO active centers as the cathode material in aluminum organic batteries. In addition, in order to improve the electron transport rate of PTCDA, a new method is proposed in this paper, which uses physical vapor deposition (PVD) method to make PTCDA recrystallize and grow on stainless steel and quartz glass substrates to improve its crystallinity. The increase of crystallinity expands the PTCDA π–π-conjugated system, making electrons more delocalized, which is beneficial to the transmission rate of electrons and ions, thereby enhancing the conductivity of the material. The experimental results show that compared with pristine PTCDA, PTCDA(Ss) and PTCDA(G) with higher crystallinity have better cycling stability and rate capability. The DFT (density functional theory) results indicated that the electron-deficient carbonyl group in the PTCDA molecule could reversibly coordinate/dissociate with the positively charged Al complex ions (AlCl2 +). This research work provides insights into the rational design of low-dimensional, high-crystallinity, high-performance cathode materials for green aluminum organic batteries.

“…The combination of PCM and porous support materials has attracted more interest because of its simple preparation process and low price. The widely used porous support materials include SiO 2, 34,35 natural clay, 36 aerogel, 37 foamed metal, 24,38 and porous carbon foam 39‐42 . Among them, porous carbon is considered to be one of the most promising support matrix materials for increasing heat transfer rate, which is superior to other inorganic materials and porous polymers because of its customized porosity and good thermal conductivity 43 .…”

Recently, the technology of employing phase change materials (PCMs) for solar energy storage has grown more magnetic due to the focus of various latent heat storage investigations to solve the energy crisis. In this work, a novel and ecofriendly shape-stable phase change material based on a biological matrix was prepared through vacuum impregnation, which used porous carbon as a support substrate from Cyperus alternifolius (CA), polyethylene glycol (PEG) as the phase change medium, and silver nanoparticles attached to the matrix as the reinforcement factor. The superior porous structure of CA allows it to have a high loading rate of PEG. The multifunctionality of silver nanoparticles can increase the thermal conductivity of the bio-based shape-stable phase change material (BSPCM) up to 0.676 W/(m K), while also boosting its photo-thermal conversion efficiency to 82.7%. Furthermore, the Ag@BSPCM has an excellent melting enthalpy of 137.3 J/g, as well as outstanding thermal stability and reliability. Additionally, the great photo-to-thermal conversion efficiency of Ag@BSPCM (82.7%) and the significant anti-leakage capability bodes well for its future application. This demonstrates the prepared Ag@BSPCM proves its feasibility for thermal energy storage management and photo-thermal conversion.
