The effect of a graphene support on the properties of Pt electrode catalysts in fuel cells

Influence of graphene sheet properties as supports of iridium-based N-heterocyclic carbene hybrid materials for water oxidation electrocatalysis

“…[22,23]. Catalytic applications are not an exception and there are a great number of studies in which graphene materials act as proactive supports of nanoparticles [24] or even organometallic compounds [25] in different catalytic systems [17,26]. Much more scarce are the studies focused on the graphene properties themselves and the influence of their structural properties on the catalytic performance of the resulting supported hybrid catalytic systems, being most of them centered in studying the effect of graphene sheet reduction.…”

Platinum single-atom adsorption on graphene: a density functional theory study

“…Tremendous efforts have been devoted to achieve these goals, including the use of non-precious metals for Pt-metal alloys, [3][4][5][6][7][8][9] or the use of noble metal-free catalysts. [10][11][12][13] Particularly interesting are Pt clusters supported by graphitic materials, such as carbon black, carbon nanotubes, and graphene, which have been extensively studied both experimentally, [14][15][16][17][18][19][20] and theoretically. [21][22][23][24][25][26][27][28][29][30][31][32][33][34] A better catalytic activity of small Pt clusters supported by graphene sheets has been demonstrated experimentally.…”

Ligand effect of SnO2 on a Pt–Ru catalyst and the relationship between bond strength and CO tolerance

“…13 Aside from Pt alloys, supports can also affect the Pt electronic structure. Nakamura et al reported evidence that interaction of Pt with a support results in modification of the Pt electronic structure and lowering adsorption energy of CO. [14][15][16][17] PtMo/C (ref. 8,[18][19][20] and PtSnO x (ref.…”
