“…These results show the insignificant increase in binding energy which could be assigned to the formation of metal oxides/(oxy)hydroxides during the OER process. 29,44,61,62 Additionally, the HR-XPS peaks of C 1s and N 1s do not show any significant changes in the binding energy after the stability test. On the other hand, the HR-XPS spectra of P 2p after the stability test reveal the disappearance of 2p 3/2 and 2p 1/2 peaks located at (129.4 and 130.2) eV respectively and the P–O peak shifts from 134.4 eV to 134.5 eV due to conversion of the metal phosphide to a metal oxide/(oxy)hydroxide.…”

“…Among two-dimensional nanomaterials, GR is the most powerful nanomaterial and has been widely used in many fields [ 37 ]. Meanwhile, as a new anionic clay material, LDH has broad application prospects in flame retardancy [ 38 ], pollutant adsorption [ 39 ], catalytic synthesis [ 40 ], medical treatment and other fields, raising the demand for it in recent years [ 41 ]. Based on the excellent properties and good application prospects of GR and LDH, this review introduces the preparation and applications of these two typical two-dimensional materials-Mt composites respectively, which could be extended to other composites with two-dimensional materials.…”

Montmorillonite (Mt) is a kind of 2:1 type layered phyllosilicate mineral with nanoscale structure, large surface area, high cation exchange capacity and excellent adsorption capacity. By virtue of such unique properties, many scholars have paid much attention to the further modification of Mt-based two-dimensional (2D) functional composite materials, such as Mt-metal hydroxides and Mt-carbon composites. In this review, we focus on two typical Mt-2D nanocomposite: Mt@layered double hydroxide (Mt@LDH) and Mt@graphene (Mt@GR) and their fabrication strategies, as well as their important applications in pollution adsorption, medical antibacterial, film thermal conduction and flame-retardant. In principle, the prospective trend of the composite preparation of Mt-2D nancomposites and promising fields are well addressed.

“…Considering the electrochemical performances of the electrode material are associated with transportation of electrolyte and electrochemical reaction, a hierarchical hollow nanostructure will be bene t for their electrochemical properties [32,33]. In addition, the two-dimensional (2D) nanosheet can provide rich accessible active sites, so a hierarchical porous structure catalyst composed of MoP/MoS 2 nanosheets with rich heterojunctions may be a superior electrocatalyst for HER.…”

Electrocatalytic production of hydrogen from water is a promising and sustainable strategy. Herein, hierarchical tubular MoP/MoS 2 composites with the wall composed of loosely stacked nanosheets were fabricated through partially phosphating the tubular MoS 2 . As an electrocatayst for hydrogen evolution reaction (HER), the hierarchical tubular MoP/MoS 2 composite displayed a superior HER activity with a low overpotential (101 mV) to obtain a current density of 10 mA/cm 2 , small Tafel slope (56 mV/dec).Moreover, the MoP/MoS 2 composite demonstrate superior long-term durability in acid electrolytes. The excellent catalytic activity of MoP/MoS 2 composite may be ascribed to its hierarchical structure: hierarchical porous structure can offer mass diffusion pathways, and the nanosheets with MoP/MoS 2 heterojunctions can provide rich active sites for HER. Density functional theory (DFT) calculations reveal that more favorable H* adsorption kinetics on the surface of the MoP/MoS 2 composite during the HER process than pristine MoP and MoS 2 . This work can offer a strategy to design high performance electrocatalysts for HER applications.
