在这里，我们报告了一种新的策略，从商业上可获得的和低成本的三聚氰胺海绵制造大孔/介孔碳整体。该合成路线包括嵌段共聚物与甲阶酚醛树脂在三聚氰胺海绵上的协同自组装和包覆，然后在不同温度下热解。所制备的炭块具有较高的孔隙率和良好的疏水性，因此可以用作从水中去除油的潜在吸附剂。所得炭块固有的耐火性能使其成为一种可回收的油水分离吸附剂。更重要的是，得益于低成本，可用的原料和简单的合成路线，碳整体的生产可以很容易地放大。本工作为制备碳整体材料提供了一条简单的途径，碳整体材料在溢油处理领域具有广阔的应用前景。(C)2014爱思唯尔有限公司版权所有。
Here we report a new strategy for fabrication of macro/mesoporous carbon monolith from commercially available and low-cost melamine sponge. This synthesis route involves the cooperative self-assembly and coating of block copolymer mixed with resol on the melamine sponge, followed by pyrolysis at different temperatures. The as-fabricated carbon monolith exhibits high porosity and excellent hydrophobicity, thus can be used as a potential sorbent for the removal of oil from water. The intrinsic fire-resistant property of obtained carbon monolith makes it a recyclable sorbent for oil-water separation. More importantly, benefiting from the low-cost, available raw material and simple synthesis route, the production of the carbon monolith can be easily scaled up. This work offers a simple pathway to prepare carbon monolith, which is a promising candidate in the field of oil spill cleanup. (C) 2014 Elsevier Ltd. All rights reserved.
