“…Our multinary NPs prepared using the IL synthesis strategy are much smaller compared to the ones of Chen et al [ 11 ]. The small size makes them particularly suitable in different fields such as dye degradation [ 30 ], hydrogen evolution [ 31 ], methanol oxidation [ 32 ] or as ORR catalyst [ 27 ].…”

Controlling the amorphous or crystalline state of multinary Cr-Mn-Fe-Co-Ni alloy nanoparticles with sizes in the range between ~1.7 nm and ~4.8 nm is achieved using three processing routes. Direct current sputtering from an alloy target in the ionic liquid 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide leads to amorphous nanoparticles as observed by high-resolution transmission electron microscopy. Crystalline nanoparticles can be achieved in situ in a transmission electron microscope by exposure to an electron beam, ex situ by heating in vacuum, or directly during synthesis by using a high-power impulse magnetron sputtering process. Growth of the nanoparticles with respect to the amorphous particles was observed. Furthermore, the crystal structure can be manipulated by the processing conditions. For example, a body-centered cubic structure is formed during in situ electron beam crystallization while longer ex situ annealing induces a face-centered cubic structure.

“…In this experiment, Pt NPs were evenly distributed on the modified glassy carbon electrode (GCE), increasing the contact area of catalysis. The result showed that this material effectively reduced the value of onset potential and increased current density . Other alloys with different proportion of Pt were detected for the effect of catalysis in Figure …”

As a class of metal-organic frameworks (MOFs) formed by association of metal cations Cu 2+ with organic ligands benzene tricarboxylic acid, HKUST-1 [1] and its derivatives have attracted much concern as they possess highly porosity, ultrahigh surface area, and the tunable structure which show its potential in various applications. Unlike other porous materials like graphene (GN), [2] multiple layers of carbon nanotube (MCNT), [3] In recent decades, metal-organic frameworks (MOFs) have achieved rapid development owing to the considerable concern from researchers. As one of the most intensely studied MOFs, HKUST-1 has shown remarkable performance which is considered feasible to apply in actual applications. However, the weak mechanical properties and water instability hinder its development which are mainly ascribed to lattice defects and surface barriers that impede mass transfer and molecular diffusion as well as electronic transmission. This review summarizes the recent literatures on the strategies of enhancing the above defects of virgin HKUST-1 and its various applications, mainly adsorption and separation, catalyst, sensor as well as optical and electronic applications. These improving strategies improve specific properties of HKUST-1 by decreasing the defects density, which will make this material more applicable for potential fields. Main strategies include the following: (1) modifying HKUST-1 with an "armor," (2) getting durable MOFs by direct synthesis or surface hydrophobization, (3) reconstructing the moisture-degraded HKUST-1, and (4) making use of the buffer action of sacrificial bonds. . His current research focuses on metal-organic frameworks (MOFs), porous coordination polymers (PCPs), morph-genetic MOFs, biomimetic functional composite, nanomaterials, materials for energy and environment, photoelectric functional materials, and so on.

“…[10][11][12][13][14][15][16] Additionally, strong metal support interactions (SMSIs) between the Pt and alternative support materials have been shown to increase the electrochemical activity of Pt through electronic, charge transfer effects. 10,11,[17][18][19][20][21][22][23] As the infrastructure for the hydrogen economy grows, due to a recent emphasis on renewable, clean energy sources, so does the need for large scale-up and optimisation of the Pt nanoparticle synthesis method. Moreover, alternative support materials require considerable efforts to improve the Pt utilisation, conductivity, porosity, surface area and corrosion resistance of the support 24 in order to increase the commercialisation of these catalysts.…”
