“…Table 1 summarizes the photothermal conversion efficiency of the PCM-based composites reported in the literature as well as the test result obtained from this study. It is noteworthy that MPCM-BP exhibited a higher conversion efficiency than most of the PCM composites containing optical absorbents, including graphene and graphene oxide (GO), 15,17,51 hollow carbon nanospheres, 52 carbon nanotubes (CNTs), 53,54 MXene, 14,55,56 BP nanosheets and phosphorene nanoflakes. 24,26,27 These results indicate that both BP nanosheets and Fe 3 O 4 nanoparticles are capable of acting as a highly effective optical composite absorbent to enhance the photothermal conversion and storage performance of phase-change microcapsules when decorated on their shell surface.…”

Solar photothermal energy storage using phasechange material (PCMs) provides sustainable penetration in comprehensive utilization. However, PCMs are obliged to suffer from low conversion and storage effectiveness in solar photothermal energy due to a low optical absorption capacity. In this study, we developed a type of magnetic phase-change microcapsule system with superior photothermal energy conversion efficiency. The microcapsule system was constructed with n-docosane as a PCM core and a CaCO 3 /Fe 3 O 4 composite shell surface-decorated with black phosphorus (BP) nanosheets employing a Pickering emulsion-templated precipitation technique. The presence of BP nanosheets on the capsule surface not only enhanced the emulsion stability to facilitate the fabrication of a tight CaCO 3 -based shell, resulting in a high latent heat capacity of the microcapsules, but also improved thermal conduction of the microcapsule system, promoting a fast thermal response and heat transfer. The microcapsule system shows a high phase-change enthalpy of over 120 J/g and a significant increase in thermal conductivity by over 400% compared to pure PCM. More importantly, the microcapsule system exhibits a high photothermal conversion efficiency of 95.08%, which is superior to most of the PCM-based composite materials reported in the literature. There is only 0.02% conversion efficiency lost after the 10-cycle photothermal conversion experiment for the microcapsule system, indicating a good working stability for the long-term use of solar photothermal conversion and storage. By decorating magnetic phase-change microcapsules with BP nanosheets on the shell, this study offers a new strategy for development of PCM-based composite materials for efficient harvest and utilization of solar energy.

“…For instance, the thermal conductivity of paraffin/gelatine aerogel (PA/G) was improved from 0.267 to 0.919 W m −1 K −1 with the addition of Ti 3 C 2 T x (30 wt % in the final composites), resulting in a dramatic enhancement in the thermal responsibility (indicated by the highest heating/cooling rate of PA/T‐30@G among all samples, as shown in Figure 12(c)) [160] . Furthermore, a high solar‐to‐thermal conversion efficiency of 92.6 % was reported for a dodecylamine‐based PCM system hybridized with the Ti 3 C 2 T x /pectin aerogel, and the resultant sample presented a reasonable latent heat of 218.8 kJ kg −1 [161] …”

The properties and applications of MXenes (a family of layered transition metal carbides, nitrides, and carbonitrides) have aroused enormous research interests for a decade since the successful synthesis of few‐layer transition metal carbides in 2011. Though MXenes, as the building blocks, have already been applied in various fields (such as wearable electronics) owing to the distinctive optical, mechanical and electrical properties, their thermal stability and intrinsic thermal properties were less thoroughly investigated compared to other characteristics in early reports. The pioneering theoretical prediction of the thermoelectric nature of MXenes was performed in 2013 while the first experiment‐based report concerning the degradation behavior of the 2D structure at elevated temperatures in a controlled atmosphere was published in 2015, followed by numerous discoveries regarding the thermal properties of MXenes. Herein, after a brief description of the synthesis, this Review summarized the latest insights into the thermal stability and thermophysical properties of MXenes, and further associated these unique properties with relevant applications by multiple examples. Finally, current hurdles and challenges in this field were provided along with some advices on potential research directions in the future.

Impregnating organic phase-change materials (PCMs) into biomass-derived aerogels is regarded as one of the most effective and accessible approach to address the liquid leakage issues of solid–liquid PCMs. However, the inefficient solar–thermal conversion and low thermal conductivity still restrict the large-scaled applications of organic PCMs in solar utilization fields. Herein, novel form-stable PCM composites (CMPCM-Fe) with enhanced thermal conductivity and excellent solar- and magnetic-driven thermal energy conversion and storage efficiency were fabricated by impregnating n-docosane into Fe3O4-functionalized κ-carrageenan/melanin hybrid aerogels (CMA-Fe) through vacuum impregnation. CMA-Fe effectively supported n-docosane and prevented the leakage issue during the phase transition process owing to its strong surface tension and capillary force. CMPCM-Fe exhibited high encapsulated efficiency (88.9–94.6%), satisfactory thermal storage capacity (229.1–246.9 J/g), and excellent reversible stability. The introduction of Fe3O4 nanoparticles enhanced the thermal conductivity (55.3% increased) and solar–thermal conversion efficiency (up to 93.5%) of CMPCM-Fe and endowed it with excellent magnetic–thermal conversion capacity under an alternating magnetic field. The synthesized CMPCM-Fe possesses broad application prospect in mutiresponse thermal management.
