“…Furthermore, dynamic phosphorene evolution can be recorded with advanced in situ microscopy and spectroscopy . Another avenue is the chemical equilibrium calculation for reactive radicals (e.g., P 2 concentration) that accounts for the 2D membrane formation.…”

Black phosphorus was first synthesized by Bridgman in 1914 [1] but has been less intensively studied in the past century due The successful isolation of phosphorene (atomic layer thick black phosphorus) in 2014 has currently aroused the interest of 2D material researchers. In this review, first, the fundamentals of phosphorus allotropes, phosphorene, and black phosphorus, are briefly introduced, along with their structures, properties, and synthesis methods. Second, the readers are presented with an overview of their energy applications. Particularly in electrochemical energy storage, the large interlayer spacing (0.53 nm) in phosphorene allows the intercalation/deintercalation of larger ions as compared to its graphene counterpart. Therefore, phosphorene may possess greater potential for high electrochemical performance. In addition, the status of lithium ion batteries as well as secondary sodium ion batteries is reviewed. Next, each application for energy generation, conversion, and storage is described in detail with milestones as well as the challenges. These emerging applications include supercapacitors, photovoltaic devices, water splitting, photocatalytic hydrogenation, oxygen evolution, and thermoelectric generators. Finally the fast-growing dynamic field of phosphorene research is summarized and perspectives on future possibilities are presented calling on the efforts of chemists, physicists, and material scientists

“…[13][14][15][16] Researchers have developed some new binders such as polyrotaxanes, cross-linked carboxymethyl cellulose and citric acid polymer, polyacrylic acid and poly(ethylene glycol) diglycidyl ether with polyethylenimine for LIBs with silicon anode, [17][18][19][20][21][22][23][24][25] lithium-sulfur batteries [26][27][28][29][30][31][32] and other rechargeable batteries. [33][34][35][36][37][38][39] The binders with ionic conductivity are of great interest, due to the fact that they will enhance lithium ion conductivity with high rate capability of LIBs. Recent studies have shown that using lithiated ionomers as binders will provide a path between electroactive materials and electrolytes, which reduces the polarization resistance and increases the ionic conductivity within the electrodes.…”

“…It also means that a chemical composition of GO doesn't play a decisive role in shaping the Raman response. Rather, a hybridization of defect sites is responsible for the intensity and line width of the Raman bands 47,48,49,50 . in the sample with 31 at.% of oxygen, the resistance reaches a value beyond our instrument range.…”

Chemical Oxidation of Graphite: Evolution of the Structure and Properties

et al. 2017

Graphene oxide is a complex material whose synthesis is still incompletely understood. To study the time evolution of structural and chemical properties of oxidized graphite, samples at different temporal stages of oxidation were selected and characterized through a number of techniques: X-ray photoelectron spectroscopy for the content and bonding of oxygen, X-ray diffraction for the level of intercalation, Raman spectroscopy for detection of structural changes, electrical resistivity measurements for probing charge localization on the macroscopic scale, and scanning 2 transmission electron microscopy for the atomic structure of the graphene oxide flakes. We found a non-linear behavior of oxygen uptake with time where two concentration plateaus were identified: uptake reached 20 at.% in the first 15 minutes, and after one hour a second uptake started, reaching a highest oxygen concentration of more than 30 at.% after two hours of oxidation. At the same time, the interlayer distance expanded to more than twice the value of graphite and the electrical resistivity increased by 7 orders of magnitude. After four days of chemical processing, the expanded structure of graphite oxide became unstable and spontaneously exfoliated; more than two weeks resulted in a significant decrease of the oxygen content accompanied by re-aggregation of the GO sheets. These correlated measurements allow us to offer a comprehensive view into the complex oxidation process.
