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

无疏水涂层高效处理粘性原油泄漏的低温碳化策略：CoFe-PBA 催化超疏水阻燃三聚氰胺海绵的碳化
由于吸收粘稠原油较困难，迫切需要具有优良光热性能和油水分离能力的碳海绵来降低粘度，有利于吸油。但高温炭化制备导致力学性能差、吸收容量低、制备条件苛刻。为了解决这些挑战，通过在源自金属有机框架（MOF）的钴铁普鲁士蓝（CoFe-PBA）界面组装海绵并进行低-疏水性阻燃三聚氰胺海绵（CPBA@CMS）设计。氮气下高温催化碳化。结果表明，CPBA@CMS具有优异的超疏水性能（水接触角= 169.7°）和吸油能力（80.7–219.5 g g -1）。此外，CPBA@CMS表现出显着的光热效应和导热性，使其能够适应各种环境条件。在1 kW m − 2太阳辐射下可迅速升至141 ℃ ，最大吸油率达到98%，最高吸油量为105.5 g g −1。此外，CPBA@CMS具有显着的消防安全性能，热释放率降低84.2%，烟雾系数降低97.5%，CO释放率降低81.4%。它为有效解决原油泄漏问题提供了高效、安全、可持续的实用解决方案。
