Abstract: Few-layered graphene networks composed of phosphorus and nitrogen dual-doped porous graphene (PNG) are synthesized via a MgO-templated chemical vapor deposition (CVD) using (NH4)3PO4 as N and P source. P and N atoms have been substitutionally doped in graphene networks since the doping takes place at the same time with the graphene growth in the CVD process. Raman spectra show that the amount of defects or disorders increases after P and N atoms are incorporated into graphene frameworks. The doping levels of P… Show more

“…[ 5a , 23 ] The High-resolution XPS spectra with curve fi ttings for p2p spectra of RGO-HCCP could be deconvoluted into two peaks (Figure 4 g). The peaks at 134.3 and 133.6 eV were P−O and C−PO 3 , [ 24 ] which played important roles in the fi re resistance.…”

“…The first of such investigations was the study of the transport properties of PN dual-doped graphene [33]. This material has been synthesized recently and proved to be an excellent catalyst for hydrogen evolution reactions [34], as well as anode materials for Li batteries [35]. Undoubtly, the most investigated member of the family of dual doped systems is SN dual doped graphene [36][37][38][39][40][41][42][43][44].…”

“…The peaks at 132.0 and 133.2 eV are related to the C 3 -PO, C 2 -PO 2 , and C-PO 3 . And, P-O bonding and P-C bonding are present at 134.3, 130.8 and 134.3 eV [29]. From the XPS results, we could speculate that N, P and S were covalently bonded with C in graphene lattice successfully.…”
