“…The MA exhibits a sharp weight loss between 225 and 345°C. In this temperature range, MA easily sublimates with very little residue [42]. FGO presents a similar thermal decomposition behavior to GO.…”

Graphene oxide (GO) is modified by melamine (MA) via the strong p-p interactions, hydrogen bonding, and electrostatic attraction. PP composites are prepared by melt compounding method, and GO/functionalized graphene oxide (FGO) is in situ thermally reduced during the processing. The results of scanning electron microscopy and transmission electron microscopy indicate that FGO nanosheets are homogeneously dispersed in polymer matrix with intercalation and exfoliation microstructure. The FGO/PP nanocomposite exhibits higher thermal stability and flame retardant property than those of the GO counterpart. During the thermal decomposition, the intercalated MA is condensed to graphitic carbon nitride (g-C 3 N 4 ) in the confined micro-zone created by GO nanosheets. This in situ formed g-C 3 N 4 provides a protective layer to graphene and enhances its barrier effect. The heat release rate and the escape of volatile degradation products are reduced in the FGO-based nanocomposites.

“…In addition, the prohibitive cost of the platinum catalysts as well as its limited supply in nature, has hindered the large-scale commercialization of PEMFCs [4]. Therefore, various types of non-precious ORR catalysts have been investigated to rival platinum, including transition metal chalcogenides [5,6], metal-N4 chelate macrocycles [7,8], conductive polymer-derived materials [9,10], nitrogen-doped graphene or carbon nanotubes [11,12], and carbon nitride [13,14]. Problems degrading these catalysts include insufficient activity and low stability [15].…”

“…3a), which may be owing to incomplete decomposition and further agglomeration of CC-300. The formation of GNS inside N-BC@G-900 mainly derives from thermal polycondensation of melamine at 600°C, following by the heat-treatment at high temperatures [29,30]. The GNS has not been found at the SEM image of N-BC-900 derived from CC-300 only, but many nano-pores are observed (Fig.…”
