Synergistic enhancement of nitrogen and sulfur co-doped graphene with carbon nanospheres insertion for electrocatalytic oxygen reduction reaction

Journal Article Wu, Min ; Xin, Huolin L. ; Wang, Jie ; ... - Journal of Materials Chemistry. A

A nitrogen and sulfur co-doped graphene/carbon black (NSGCB) nanocomposite for the oxygen reduction reaction (ORR) was synthesized through a one-pot annealing of a precursor mixture containing graphene oxide, thiourea, and acidized carbon black (CB). The NSGCB showed excellent performance for the ORR with the onset and half-way potentials at 0.96 V and 0.81 V (vs. RHE), respectively. It is significantly improved over that of the catalysts derived from only graphene (0.90 V and 0.76 V) or carbon nanosphere (0.82 V and 0.74 V). The enhanced catalytic activity on the NSGCB electrode could be attributed to the synergistic effect of N/Smore »« less

Synergistic enhancement of electrocatalytic CO₂ reduction to C₂ oxygenates at nitrogen-doped nanodiamonds/Cu interface

Journal Article Wang, Hongxia ; Tzeng, Yan-Kai ; Ji, Yongfei ; ... - Nature Nanotechnology

To date, effective control over the electrochemical reduction of CO₂ to multicarbon products (C ≥ 2) has been very challenging. Here, we report a design principle for the creation of a selective yet robust catalytic interface for heterogeneous electrocatalysts in the reduction of CO₂ to C₂ oxygenates, demonstrated by rational tuning of an assembly of nitrogen-doped nanodiamonds and copper nanoparticles. The catalyst exhibits a Faradaic efficiency of ~63% towards C₂ oxygenates at applied potentials of only -0.5 V versus reversible hydrogen electrode. Moreover, this catalyst shows an unprecedented persistent catalytic performance up to 120 h, with steady current and onlymore »« less

Metal-organic frameworks derived platinum-cobalt bimetallic nanoparticles in nitrogen-doped hollow porous carbon capsules as a highly active and durable catalyst for oxygen reduction reaction

Journal Article Ying, Jie ; Li, Jing ; Jiang, Gaopeng ; ... - Applied Catalysis B: Environmental

Pt-based nanomaterials are regarded as the most efficient electrocatalysts for the oxygen reduction reaction (ORR) in proton exchange membrane fuel cells (PEMFCs). However, widespread adoption of PEMFCs requires solutions to major challenges encountered with ORR catalysts, namely high cost, sluggish kinetics, and low durability. In this paper, a new efficient method utilizing Co-based metal-organic frameworks is developed to produce PtCo bimetallic nanoparticles embedded in unique nitrogen-doped hollow porous carbon capsules. The obtained catalyst demonstrates an outstanding ORR performance, with a mass activity that is 5.5 and 13.5 times greater than that of commercial Pt/C and Pt black, respectively. Most importantly,more »« less

Pt alloy nanoparticles decorated on large-size nitrogen-doped graphene tubes for highly stable oxygen-reduction catalysts

Journal Article Chen, Mengjie ; Hwang, Sooyeon ; Li, Jiazhan ; ... - Nanoscale

Pt alloy nanoparticles supported on Vulcan XC-72 (Pt/C) are the most effective catalysts for kinetically sluggish oxygen reduction reaction (ORR) in proton exchange membrane fuel cells. However, significant performance degradation has been observed with the Pt/C catalysts due to agglomeration and Ostwald ripening of Pt nanoparticles largely resulting from the corrosion of carbon supports. In this paper, we developed a Pt alloy catalyst through annealing Pt nanoparticles deposited on nitrogen/metal co-doped large-size graphene tubes (NGTs). The in-situ formation of PtM (M: Co and Ni) alloy during the annealing process contributes to the improvement of the catalytic activity and stability. Duringmore »« less
