This work reports a novel approach for the synthesis of FeCo alloy nanoparticles (NPs) embedded in N,P-codoped carbon coated nitrogen-doped nanotubes (NPC/FeCo@NCNTs). Specifically, NCNT is achieved by calcination graphene oxide-coated polystyrene spheres with Fe
Development of inexpensive, efficient, and stable nonprecious-metal-based bifunctional catalysts for oxygen reduction (ORR) evolution (OER) reactions remains an enormous challenge. This work reports on excellent electrocatalyst consisting ultrathin N-doped carbon (1–3 graphitic layers) coated Fe1.2Co nanoparticles nanotubes (Fe1.2Co@NC/NCNTs). The Fe1.2Co@NC/NCNTs have extremely low Fe/Co content (6.7 wt %), but with highly efficient durable bifunctionality ORR OER. Specifically, the...
Abstract This work reports the use of defect engineering and carbon supporting to achieve metal-doped phosphides with high activities stabilities for hydrogen evolution reaction (HER) oxygen (OER) in alkaline media. Specifically, nitrogen-doped nanofiber-supported Ni-doped CoP 3 rich P defects (Pv·) on cloth (p-NiCoP/NCFs@CC) is synthesized through a plasma-assisted phosphorization method. The p-NiCoP/NCFs@CC an efficient stable catalyst HER OER. It only needs overpotentials 107 306 mV drive...
Amine functionalized holey graphene (AFHG), synthesized by the hydrothermal reaction of GO and ammonia subsequent KOH etching, has been used as a metal-free catalyst for oxygen reduction (ORR). It shows that AFHG is highly active ORR exhibits higher electrocatalytic activity than graphene, nitrogen-doped (NG) amine (AFG), which could be demonstrated from its current density more positive half-wave onset potentials ORR. Although also slightly overpotential towards ORR, it indeed kinetically...
NiFe alloy NPs anchored in NGHS wrapped with self-grown NCNTs a three-dimensional architecture was constructed successfully for ORR/OER bifunctional catalysis.
Boron and nitrogen codoped hollow graphene microspheres (NBGHSs), synthesized from a simple template sacrificing method, have been employed as an electrocatalyst for the oxygen reduction reaction (ORR). Because of their specific structure that consists boron graphene, NBGHSs can exhibit even high electrocatalytic activity toward ORR than commercial JM Pt/C 40 wt %. This, along with higher stability, makes particularly attractive great potential to replace commonly used noble-metal-based catalysts.
The membranes constructed from sodium dodecylbenzenesulfonate adsorbed holey graphene oxides (SDBS-HGO)s have been used as proton exchange for air-breathing direct methanol fuel cell applications. Due to the specific structure of oxide which provides additional transport pathways protons across nanosheet and presence strong groups provide them with high conductivity, SDBS-HGO exhibit comparable conductivity lower permeability in comparison commercial Nafion® 112. electrochemical results show...
Nitrogen-doped graphene sheets with different active center structures, such as amine N, quaternary pyridinic or pyrrolic N atoms, were successfully fabricated using targeted nitrogen precursors and a designed annealing process. Then, the nitrogen-doped structure is used for growth of Co3O4 nanoparticles. The investigation results reveal that interaction between loaded particles atoms doped in stronger than those leads to smaller particle size high specific surface area composite electrodes...
Sulfonated holey graphene oxides (SHGOs) have been synthesized by the etching of sulfonated with concentrated HNO3 under assistance ultrasonication. These SHGOs could be used as fillers for aromatic poly(ether ether ketone) (SPEEK) membrane. The obtained SHGO-incorporated SPEEK membrane has a uniform and dense structure, exhibiting higher performance proton exchange membranes (PEMs), instance, conductivity, lower activation energy conduction, comparable methanol permeability, compared to...

Specifically, prepared at 800 °C shows better...
Abstract This work utilizes defect engineering, heterostructure, pyridine N‐doping, and carbon supporting to enhance cobalt‐nickel selenide microspheres' performance in the oxygen electrode reaction. Specifically, microspheres mainly composed of CoNiSe 2 Co 9 Se 8 heterojunction rich selenium vacancies (V Se· ) wrapped with nitrogen‐doped nanotubes (p‐CoNiSe/NCNT@CC) are prepared by Ar/NH 3 radio frequency plasma etching technique.
