Pt-based composite nanoparticles for magnetic, catalytic, and biomedical applications

Synthesis and characterization of a quaternary nanocomposite based on TiO2/CdS/rGO/Pt and its application in the photoreduction of CO2 to methane under visible light

“…27,28 More recently, many researchers have reported increases in the photocatalytic activity of several semiconductors by preparing composites with MWCNTs or graphene-based materials. 34 These nanocomposites are currently considered to be the most effective catalysts for hydrogen evolution 35 and for CO 2 reduction, 36 primarily because of their stability, chemical inertness and high catalytic activity. 32 Metal nanoparticles commonly used as co-catalysts are Ni, Ti, Co, Rh, Ir and Pt.…”

Self‐Supported Interconnected Pt Nanoassemblies as Highly Stable Electrocatalysts for Low‐Temperature Fuel Cells

“…It has been argued that the loss of ECSA is mainly ascribed to the corrosion of carbon supports, which further results in migration, aggregation, and Ostwald ripening of Pt NPs because of their high surface energy and zero-dimensional (0D) structural features. [13,17] Nevertheless, most of the reported 1D Pt nanocatalysts are in the form of freestanding nanocrystals, which are similar to the Pt/CB catalyst. [14][15][16] Meanwhile, the 1D Pt nanostructures have a unique combination of dimensions in multiple length scales, and they do not require a high surface-area support (e.g.…”

Tuning crystal structure and magnetic property of dispersible FePt intermetallic nanoparticles

“…Among them, FePt NPs have been extensively studied due to their great potential in data storage, electrocatalysis and biomedicine [2][3][4]. Magnetic property of FePt NP is dominated by its crystal structure, which is very essential for different magnetic applications.…”
