2018年10月9日 · Few-layer black phosphorus (BP), a two-dimensional (2D)-layered semiconductor that can be exfoliated from bulk BP, has been attracting increasing interest...

Black phosphorus (BP) has received increasing research attention as an anode material in sodium-ion batteries (SIBs), owing to its high capacity, electronic conductivity, and...

2015年3月3日 · X-ray diffraction (XRD) patterns (A) and scanning X-ray photoelectron spectra (XPS) results (B) for few layered BP and BP@TiO 2. hybrid photocatalysts.

2020年12月15日 · X-ray photoelectron spectroscopy (XPS) was also employed to investigate the surface element variation of BP nanosheet. As shown in the XPS survey spectra of BP-PDA and BP-Bulk (Fig. 2 b), it should be noted that the peak assigned to N 1 s is observed in PDA and BP-PDA, while not found in BP-Bulk. The atom percentage of oxygen and carbon for BP ...

2020年8月6日 · The high-resolution XPS spectrum of P 2p presents doublet characteristic peaks of crystalline BP at 129.7 eV of P 2p 3/2 and 130.5 eV of P 2p 1/2, respectively 36, as well as two small peaks at...

Black phosphorus (BP) nanosheet (NS) is an emerging oxygen evolution reaction (OER) electrocatalyst with both high conductivity and abundant active sites. However, its ultrathin structure suffers instability because of the lone pair electrons exposed at the surface, which badly restricts durability for achieving long-term OER catalysis.

2021年9月24日 · The surface chemical composition of BP and BP/HATs sheets was elucidated by X-ray photoelectron spectroscopy (XPS). As depicted in Figure 2h and Figure S8 (Supporting Information), the P 2p 3/2 and P 2p 1/2 peaks of pristine BP are located at 129.9 and 130.7 eV, respectively, in good agreement with the previous reports.

Black phosphorus (BP), the bulk counterpart of monolayer phosphorene, is a relatively stable phosphorus allotrope at room temperature. However, monolayer phosphorene and ultra-thin BP layers degrade in ambient atmosphere. In this paper, we report the investigation of BP oxidation

X-ray photoelectron spectroscopy (XPS) were recorded to further verify the structural integrity of F-BP. XPS spectra shown in Figure 1g reveal that the band associated with P 2p and P 2s appear at about 134 and 191 eV, respectively, which are the key features of highly crystalline BP.

2021年11月24日 · Black phosphorus (BP) with layered structure has been deemed as a promising anode material for Li-ion batteries (LIBs). However, BP exhibits volume expansion and poor environment stability during the discharge/charge process. Here, CoP nanoparticles were introduced onto BP nanosheets to improve the electrochemical performance of LIBs.
