New shape‐stabilized paraffin/porous carbon materials derived from metal organic gel (cMOG)/boron nitride (BN) composites were prepared by the impregnation method. In the composites, paraffin was used as phase change material, while cMOG as a supporting and loading large paraffin content in the pores owing to high specific surface area and BN employed to enhance the thermal conductivity. The scanning electron microscopy images showed better filler–filler connectivity in BN/cMOG than the individual supporting materials. With the synergy of BN and cMOG, the thermal conductivity of BN/cMOG/PCM composites exhibited up to 232.1 % of pristine PCM and 82.3 % of binary BN/PCM composites at the same wt.‐% of BN. The latent heat as‐synthesized composite attains up to 163.1 J/g with up to 80 wt.‐% of paraffin retained in the composites without any leakage. In addition, the composites revealed enhanced heat transfer performance in both the solid and liquid states. Similarly, the XRD and FTIR analysis showed excellent chemical compatibility between paraffin and the supporting materials. In addition, the composite has high thermal stability, reduced supercooling extent, and better reliability after 200 times thermal cycling, which indicate a promising method for large‐scale thermal energy storage. Shape‐stabilized porous carbon materials derived from metal organic gel/BN/paraffin were prepared. They have enhanced heat transfer performance in both the solid and liquid phases and large energy storage capacity. [ABSTRACT FROM AUTHOR]

• Hierarchical Co-embedded porous carbon microspheres were controllably synthesized. • The Co-based catalyst showed superior performance beyond noble-metal-based catalysts. • The partially uncovered and totally in-built Co species were likely the active sites. The direct pyrolysis of metal organic frameworks (MOFs) has recently provided an effective method to prepare various metal-incorporated composite carbon materials. In this work, hierarchical Co-embedded N-doped porous carbon microspheres were synthesized by controlled pyrolysis of bimetallic Zn-Co Prussian blue analogues (PBAs), in which the metallic Zn component served as thermally removable template and ligand [Co(CN) 6 ]3− served as both Co and N sources. When devoted to catalyzing the reduction of 4-nitrophenol (4-NPh) into 4-aminophenol (4-APh), the optimized catalyst exhibited a large apparent rate constant of 1.35 min−1 and high turnover frequency (TOF) of 0.0204 s−1, which was superior to the majority of noble-metal-based catalysts. Besides, a home-made continuous flow catalysis system was readily constructed. Control experiments confirmed that both partially uncovered and totally in-built active metallic Co species acted as catalytically active sites. This work might provide a further understanding of the identification of active sites within metal-incorporated carbon-based catalysts. [ABSTRACT FROM AUTHOR]
