Polyoxomolybdate anchored graphite oxide: Noble metal-free electrocatalyst for oxygen reduction reaction

Growth of polyoxomolybdate with a porous pyramidal structure on carbon xerogel nanodiamond as an efficient electro-catalyst for oxygen reduction reaction

“…In addition, the two peaks located at 232.9 eV and 235.9 eV correspond to 3d 5/2 and 3d 3/2 of Mo (+VI) state. 19 In the case of POM@CDNPs the Mo 3d spectrum, Fig. 6d, was deconvoluted into five peaks which are ascribed to Mo–N (228.6 eV), the peak at 231.5 eV and 234.3 eV corresponding 3d 5/2 and 3d 3/2 of Mo (+V) state.…”

Fe3O4@SiO2-PMA-Cu magnetic nanoparticles as a novel catalyst for green synthesis of β-thiol-1,4-disubstituted-1,2,3-triazoles

“…These peaks are compatible with the standard data (JCPDS: 00–43-0317) 72 . The significant diffraction peaks are observed in case of PMA at 2Ө = 8.95°, 18.49°, 26.43°, 27.65° and 28.84° corresponding to (011), (202), (141), (311) and (312) crystallographic planes respectively (JCPDS: 00–043-0317) 73 . The broad peak at 2Ө = 22.90° is related to the amorphous SiO 2 shell on the surface of Fe 3 O 4 67 .…”

Design of Co-Sn bimetallic nanoalloys as electrocatalyst for alkaline methanol oxidation reaction: Exploring the effect of electroactivation process

“…Thanks to the state-of-art developments in nanotechnology specifically synthesis of multifunctional nanomaterials such as metal-based nanocomposites [15][16][17][18], hydrogels/aerogels and their composites [19,20], carbonaceous materials , polymers and their composites [21,22] have been garnered substantial attention thanks to their possible utilization in various application areas such as biomedical [23], environmental applications [24][25][26][27][28], energy [29,30] , sensors [31][32][33][34] as well as catalyst [35][36][37], etc. Hence, benefiting from the advantages of the recent developments in nanomaterial science, it is of great importance to tailor and design noble-metal free electrocatalysts to be utilized in low-cost high-performance DMFCs [38]. Among various alternative electrocatalysts, tinbased alloys (M x Sn y : M = Co, Ni, Sb, Ag, Cu, Fe, etc.)…”
