“…The hierarchical mesopores maybe generated during the carbonization process lies in the release of N2 and NH3, since the molecular formula (C3H6N6CH2O) of the raw MF foam material contains a lot of nitrogen atoms and hydrogen atoms. [19] The X-ray diffraction (XRD) pattern (Fig. 3b) of MF-G control and MF carbon sponge both illustrate two broad peaks at about 26° and 43°, which can be indexed to the (002) and (100) plane of graphitic carbon (PDF#75-1621), respectively.…”

The clean-up of spilled viscous crude oil has increasingly become a global challenge. Since the rather limited sorption speed restricted the use of traditional oil sorbents materials in practical oil-spill remediation, people gradually pay more attention to the nanoporous materials and technology to clean-up viscous crude oil by turning the rheology though Joule-heating. Herein, we report a quite easy synthesis method to prepare light-weight nanoporous carbon sponges by using the cheap environmentally friendly melamine foam, a widely used and mass disposal building material with high porosity of over 99%, as the template and carbon source. SEM images show that the natural 100 um level porous network structure of melamine foam retained after the carbonized carbon sponge material. Nitrogen adsorption-desorption isotherms as well as the corresponding pore size distribution results clearly indicating the unique hierarchical mesoporous features of the as-developed carbon sponge, which is good for its contract with the spill oil. XRD and Raman spectra verified the partial graphitization characteristics of the mesoporous carbon sponges, FT-IR and XPS spectra confirmed the presence of N and O containing functional groups. The Joule-heating performance in a simulated oil spill case under sunlight show that the obtained mesoporous carbon sponges superior than supported graphene control (MF-G) on the heating and rheological regulation effect, thus is an excellent candidate for oil spill recovery. The synthetically balanced physicochemical characteristics and additional merits such as low cost, enriched oxygen-containing functional groups, good bulk electrical conductivities and robustness make this carbon sponge material a good platform for the development of various advanced multifunctional materials for oil spill recovery.

“…Zhang et al developed a simple template-free method to fabricate nitrogen-doped porous carbon foam from melamineformaldehyde foam by a two-step pyrolysis process: heating at 300 C in air and then at 1000 C in a N 2 atmosphere. 110 This carbon foam (4.3 at% N content) has a small pore size below 5 nm and gives rise to a high specic surface area of 980 m 2 g À1 . Rotating disk electrode (RDE) voltammograms are used to investigate the ORR pathway of this carbon foam.…”

“…More recently, many studies suggested that due to the good structural homogeneity, high internal porosity, excellent processability, and the high surface-to-volume ratio, carbon foam (CF) with 3D porous structure showed wide application in various aspects, such as supercapacitors, 18 electrochemical sensors, 19 and oxygen reduction reaction (ORR) catalysts. 20 For example, Chen reported a porous nitrogen doped carbon foam for ORR catalyst. 20 The nitrogen doped carbon foam with excellent resilience was made by direct pyrolysis of commercial melamine resin foam.…”
