Platinum Island-on-Copper–Nickel Alloy Nanoparticle/Carbon Trimetallic Nanocatalyst for Selective Hydrogenation of Cinnamaldehyde

Preparation of size-controlled LiCoPO4particles by membrane emulsification using anodic porous alumina and their application as cathode active materials for Li-ion secondary batteries

“…[1][2][3][4][5][6][7][8][9][10] Various methods have been reported for the preparation of particles with size in the submicron to nanometer scales, including the reductive deposition of metal ions in a liquid phase, chemical vapor deposition (CVD), and spray drying. [11][12][13][14] Among them, membrane emulsication has been attracting considerable attention as an effective method for preparing monodisperse particles with controlled sizes. In membrane emulsication, a dispersed phase is excluded into a continuous phase through an emulsication membrane with uniform-sized pores to form monodisperse droplets.…”

Dependence of size distribution of nanoparticles on hole size uniformity in membrane emulsification

“…Since the properties of nanoparticles depend on their size and shape, it is important to prepare them with uniform sizes and shapes. The chemical reduction of metal ions in a liquid phase is one of the most common methods of preparing nanoparticles [9][10][11]. However, the control of the uniformity of sizes and shapes is difficult in this method.…”

Catalytic Membrane Nanoreactor with Cu–Agx Bimetallic Nanoparticles Immobilized in Membrane Pores for Enhanced Catalytic Performance

“…Heterostructured nanomaterials have gained increased attention because they display multiple functionalities, selectivity, superior catalytic activity, and stability compared to monometallic nanomaterials, also the respective characteristics can be retained. − The catalytic performance of any hetero-nanostructure is highly dependent on several factors, such as compositions, sizes, and shapes. − Among a number of architectures, a core–shell structure formed by supporting metal nanoparticles as islands on the core of another metal substrate stands out due to a series of benefits. − First, the loss of core activity derived from the agglomeration of the shell metal can be dramatically suppressed . Second, the catalytic activity can be guaranteed due to the small size and large specific area of the spatially separated shell metal islands. , In terms of the fabricating methods, the galvanic replacement reaction based on the potential difference is a simple method for fabricating a core–shell structure with metal islands supported on another core metal. − Basically, this method was used to deposit more noble metals with higher reduction potentials on non-noble metals with relatively lower reduction potentials so that several benefits can be achieved. First, the overall cost of catalysts can be reduced because most of the expensive noble metal particles cores can be replaced by inexpensive ones.…”
