Electrocatalytic properties of carbon supported cobalt phthalocyanine–platinum for methanol electro-oxidation

Ammonia adsorption on iron phthalocyanine on Au(111): Influence on adsorbate–substrate coupling and molecular spin

“…The appearance of similar spectral features has been observed previously for both phthalocyanines 58 and porphyrins, 59 and has been attributed to different electron configurations in either the ground (charge transfer from substrate and back donation) or core-excited (more/less efficient screening of the core hole) state. 9,59,60 Possibly, the initial and final states effects even occur simultaneously. At high binding energies other unresolved satellites might also play a role.…”

“…On solid supports, phthalocyanines and phthalocyanine derivatives form ordered monolayer structures. [2][3][4][5][6][7] Such monolayers are promising candidates for novel catalytic [8][9][10][11][12] and gas sensing applications. [13][14][15][16][17][18][19][20][21][22][23][24][25][26] Their function will depend critically on the molecular electronic structure, which for phthalocyanines containing certain transition metals (such as Cr, Mn, Fe, Co) is quite complex with an open shell structure of the d orbitals and a number of energetically close-lying electronic states.…”

Co/CeO2-decorated carbon nanofibers as effective non-precious electro-catalyst for fuel cells application in alkaline medium

“…Accordingly, because of the adsorption capacity of carbon, the later has been incorporated in many recently reported electrocatalytic materials, not only for the DMFCs but also other kinds of fuel cells [56][57][58][59][60]. In contrast to the precious metals (especially Pt), the zero valent surface of the transition metals is not responsible for the electrocatalytic activity.…”

Synthesis and characterization of Co/SrCO3 nanorods-decorated carbon nanofibers as novel electrocatalyst for methanol oxidation in alkaline medium

“…On the other hand carbon nanostructures are most widely studied as an electrocatalyst, not only for the DMFCs but also other kinds of fuel cells due to their adsorption capacity [25][26][27][28][29][30], Specially, nanofibers possess the most attentions of the researchers due to the good performance in many applications [31][32][33]. The large axial ratio of the nanofibers results in decreasing the total surface area compared to the nanoparticulate morphology, this might be considered a negative influence upon utilizing the nanofibers as catalysts.…”
