Abstract Due to the difficulty of absorbing viscous crude oil, there is an urgent need for carbon sponges with excellent photothermal properties and oil‐water separation capabilities reduce viscosity facilitate oil absorption. However, preparation high‐temperature carbonization leads poor mechanical properties, low absorption capacity, stringent conditions. To solve these challenges, a highly hydrophobic flame‐retardant melamine sponge (CPBA@CMS) designed by assembling at interface cobalt–iron Prussian blue (CoFe‐PBA) derived from metal–organic frameworks (MOFs) conducting low‐temperature catalytic under nitrogen. The results demonstrate that CPBA@CMS exhibits superhydrophobic (water contact angle = 169.7°) capacity (80.7–219.5 g −1 ). Furthermore, displays remarkable effects thermal conductivity, making it adaptable various environmental It can rapidly rise 141 °C 1 kW m − 2 solar irradiation, maximum rate reaching 98% highest 105.5 . Additionally, shows significant fire safety performance, reducing heat release 84.2%, smoke factor 97.5%, CO 81.4%, respectively. provides efficient, safe, sustainable practical solution effectively addressing spills oil.

Abstract Metal‐organic framework materials are ideal characterized by open frameworks, adjustable components, and high catalytic activity. They extensively utilized for catalysis. Due to decomposition structural collapse under temperatures an oxygen‐rich environment, the potential of thermal catalysis is greatly limited. In this research, Co‐rich hollow spheres (Co‐HSs) with a gradient composition designed synthesized investigate their properties in ammonium perchlorate（AP）system. The results demonstrate that Co‐HSs@AP exhibits good activity high‐temperature 292.5 °C, which 121.6 °C lower than pure AP. hierarchical structure confers stability during process. Thermogravimetry‐infrared indicates inclusion Co‐HSs successfully boosts level reactive oxygen species achieves thorough oxidation NH 3 . Based on above phenomenon, macro dynamics calculations carried out. show can promote circulation lattice multidimensional diffusion environment.
