Formation of platinum nanosheets between graphite layers

Graphene-supported platinum catalysts for fuel cells

“…Hybrid graphene-platinum (G-Pt) material can be traced back to 1999, and it has been developing fast for the past decade [53]. G-Pt syntheses can be broadly divided into four strategies: (1) ''One pot synthesis'' where both precursors, GO and Pt salt, are reduced simultaneously [54], (2) GO reduced in the presence of PtNPs [55], (3) PtNP precursor reduced in the presence of reduced GO (graphene) [56] and (4) ''separate reduction'' where graphene is mixed with already prepared PtNPs which are then incorporated in the graphene network [57] (Fig.…”

Preparation and Surface Activity of Single‐Crystalline NiO(111) Nanosheets with Hexagonal Holes: A Semiconductor Nanospanner

“…[2,3] However, nanosheets with desired holes have not been widely studied owing to a lack of knowledge for their preparation. To the best of our knowledge, there are only two papers regarding the synthesis of metal platinum nanosheets containing hexagonal holes and both used graphite as a template, [4,5] and there is no report on the synthesis of metal oxide nanosheets with hexagonal holes. Moreover, hard template-assisted processes have shortcomings for practical application owing to the high cost and time requirement.…”

Magnetic properties of cobalt‐carbon nanocomposites

“…MGs may be a source of new issues in solid state physics and are also very important for future industrial application in spintronics. methods of MGs' production: the synthesis by the reduction of corresponding acceptor-type metal-chloride GIC's [4][5][6][20][21][22] by hydrogen, by alkali metal vapor, by chemical reductants or by electrochemical methods. The structure, phase compositions and.…”

“…The alternative method is the intercalation of transition metal into graphite matrix [4,5]. The compounds of such type, known as metal-graphite intercalated compounds (MGs), are the attractive materials due to quasi 2D layered structure and potentially possess peculiar functional properties [6,7]. In particular, they exhibit superconductivity, magnetism, weak localization effects, depending on the position of the metal constituent in the periodic table (3d, 4d and 5d transition metals) [8][9][10][11][12][13][14][15].…”
