“…However, compared with single cocatalysts, dual cocatalysts [195,[254][255][256][257] tend to possess different functions, hence they usually emerge superiorities of higher PEC water oxidation performance due to synergetic effects caused by their interactions.

Photo‐electrochemical (PEC) water splitting, as an essential and indispensable research branch of solar energy applications, has achieved increasing attention in the past decades. Between the two photoelectrodes, the photoanodes for PEC water oxidation are mostly studied for the facile selection of n‐type semiconductors. Initially, the efficiency of the PEC process is rather limited, which mainly results from the existing drawbacks of photoanodes such as instability and serious charge‐carrier recombination. To improve PEC performances, researchers gradually focus on exploring many strategies, among which engineering photoelectrodes with suitable cocatalysts is one of the most feasible and promising methods to lower reaction obstacles and boost PEC water splitting ability. Here, the basic principles, modules of the PEC system, evaluation parameters in PEC water oxidation reactions occurring on the surface of photoanodes, and the basic functions of cocatalysts on the promotion of PEC performance are demonstrated. Then, the key progress of cocatalyst design and construction applied to photoanodes for PEC oxygen evolution is emphatically introduced and the influences of different kinds of water oxidation cocatalysts are elucidated in detail. Finally, the outlook of highly active cocatalysts for the photosynthesis process is also included.

“…The signals located at -38 and -17 ppm are due to DADB. [4][5][6]13,14,24] The signal located at -12 ppm is ascribed to the BH 2 N 2 environment, which is typical of PAB. [4][5][6]13,14] The worst thermal stability of 2 0 is thus explained by the formation of some DADB during the synthesis.…”

¹¹ B MAS NMR Study of the Thermolytic Dehydrocoupling of Two Ammonia Boranes upon the Release of One Equivalent of H₂ at Isothermal Conditions

The mechanism of thermolytic dehydrocoupling of neat ammonia borane NH3BH3 (AB) upon the release of 1 equivalent of H2 at isothermal conditions is fairly complex. Two different samples of neat AB (purity of ≥ 97%) were investigated with the help of solid‐state 11B MAS NMR. They are different in composition. Some diammoniate of diborane (DADB) and traces of LiCl were found in one of them. The solid residues forming upon the release of 0.5 and 1 equivalent of H2 were also analyzed. They are similar in composition, regardless of the nature of the starting AB. These observations indicate that the AB dehydrocoupling mechanism is not impacted by the presence of “impurity”. With respect to the composition of the residues, species showing different dehydrogenation extents (from ∼0 to ∼2.5) like for AB, DADB, polyaminoborane, polyiminoborane and polyborazylene can be identified. This suggests that the process would be heterogeneous, not uniform. This is discussed in detail herein.

“…However, these two chosen PCMs possess similar decreasing thermal conductivity trends, which restricted the effective temperature region of the thermal rectification. Another solid-state thermal diode was fabricated from the paraffinpolystyrene foam hybrid and phase invariant material (PMMA) by Wang et al, [206] which could attain a maximum thermal Adv. Funct.…”

Thermal energy storage technologies based on phase‐change materials (PCMs) have received tremendous attention in recent years. These materials are capable of reversibly storing large amounts of thermal energy during the isothermal phase transition and offer enormous potential in the development of state‐of‐the‐art renewable energy infrastructure. Thermal conductivity plays a vital role in regulating the thermal charging and discharging rate of PCMs and improving the heat‐utilization efficiency. The strategies for tuning the thermal conductivity of PCMs and their potential energy applications, such as thermal energy harvesting and storage, thermal management of batteries, thermal diodes, and other forms of energy utilization, are summarized systematically. Furthermore, a research perspective is given to highlight emerging research directions of engineering advanced functional PCMs for energy applications.
