Abstract

The present study shows a design concept for fabricating Fe-PyNG hybrid via strong coupling between FePc and pyridine-N. The prominent features of the Fe-PyNG hybrid include high electrocatalytic activity, superior durability, and better performance than Pt/C toward ORR in alkaline media. These features potentially make Fe-PyNG an outstanding nonprecious metal cathode catalyst for fuel cells. The incorporation of Fe ion and pyridine-N afforded effective bonding and synergetic coupling effects, which lead to significant electrocatalytic performance. DFT calculations indicate that N-modified Fe is a superior site for OOH adsorption and ORR reaction. Meanwhile, the strong chemical bonding between FePc and pyridyne in PyNG leads to its superior stability. We believe that our present synthetic strategy can be further extended to develop other metal complexes/N-doped carbon materials for broad applications in the field of catalysts, batteries, and supercapacitors.

In Situ Fabrication of PtCo Alloy Embedded in Nitrogen-Doped Graphene Nanopores as Synergistic Catalyst for Oxygen Reduction Reaction

Journal Article Zhong, Xing; Wang, Lei; Zhou, Hu; ... - Advanced Materials Interfaces

A novel PtCo alloy in situ etched and embedded in graphene nanopores (PtCo/NPG) as a high-performance catalyst for ORR was reported. Graphene nanopores were fabricated in situ while forming PtCo nanoparticles that were uniformly embedded in the graphene nanopores. Given the synergistic effect between PtCo alloy and nanopores, PtCo/NPG exhibited 11.5 times higher mass activity than that of the commercial Pt/C cathode electrocatalyst. DFT calculations indicated that the nanopores in NPG cannot only stabilize PtCo nanoparticles but can also definitely change the electronic structures, thereby change its adsorption abilities. This enhancement can lead to a favorable reaction pathway on PtCo/NPGmore »« less

Effect of Graphene with Nanopores on Metal Clusters

Journal Article Zhou, Hu; Chen, Xianlang; Wang, Lei; ... - Physical Chemistry Chemical Physics. PCCP, 17(37):24420-24426

Porous graphene, which is a novel type of defective graphene, shows excellent potential as a support material for metal clusters. In this work, the stability and electronic structures of metal clusters (Pd, Ir, Rh) supported on pristine graphene and graphene with different sizes of nanopore were investigated by first-principle density functional theory (DFT) calculations. Thereafter, CO adsorption and oxidation reaction on the Pd-graphene system were chosen to evaluate its catalytic performance. Graphene with nanopore can strongly stabilize the metal clusters and cause a substantial downshift of the d-band center of the metal clusters, thus decreasing CO adsorption.

Mechanistic Insights into the Structure-Dependent Selectivity of Catalytic Furfural Conversion on Platinum Catalysts

Journal Article Cai, Qiuxia; Wang, Jianguo; Wang, Yang-Gang; ... - AIChE Journal (Online)

The effects of structure and size on the selectivity of catalytic furfural conversion over supported Pt catalysts in the presence of hydrogen have been studied using first principles density functional theory (DFT) calculations and microkinetic modeling. Four Pt model systems, i.e., periodic Pt(111), Pt(211) surfaces, as well as small nanoclusters (Pt13 and Pt55) are chosen to represent the terrace, step, and corner sites of Pt nanoparticles. Our DFT results show that the reaction routes for furfural hydrogenation and decarbonylation are strongly dependent on the type of reactive sites, which lead to the different selectivity. On the basis of the size-dependentmore »« less

Synergistic Effect of Nitrogen in Cobalt Nitride and Nitrogen-Doped Hollow Carbon Spheres for Oxygen Reduction Reaction

Journal Article Zhong, Xing; Liu, Lin; Jiang, Yu; ... - ChemCatChem, 7(12):1826-1832

The need for inexpensive and high-activity oxygen reduction reaction (ORR) electrocatalysts has attracted considerable research interest over the past years. Here we report a novel hybrid that contains cobalt nitride/nitrogen-rich hollow carbon spheres (CoxN/NHCS) as a high-performance catalyst for ORR. The CoxN nanoparticles were uniformly dispersed and confined in the hollow NHCS shell. The performance of the resulting CoxN/NHCS hybrid was comparable with that of a commercial Pt/C at the same catalyst loading toward ORR, but the mass activity of the former was 5.7 times better than that of the latter. The nitrogen in both CoxN and NHCS, especially CoxN,more »« less

Geometric and Electronic Properties of Graphene Modified by “External” N-Containing Groups

Journal Article Wang, Xinde; Cai, Qiuxia; Zhuang, Guilin; ... - Physical Chemistry Chemical Physics. PCCP, 16(38):20749-20754

By means of the first-principles spin polarized density functional theory (DFT) calculations, we investigated structures and electronic properties of “external” nitrogen-containing groups (pyridine derivatives) modified graphene via single or double bonding mode. This study of single-bond pyridine derivatives modified graphene (SBPG) shows that the ortho-carbon is the most favorable adsorption site for pyridine derivatives on graphene, as confirmed by bader charge analysis. The external stability of pyridine derivatives on graphene by [2+2] cycloaddition is caused by the match between frontier orbitals of pyridine derivatives and those of graphene, which leading to the formation of stronger chemical bonds. Interestingly, electronic structuremore »« less
