Fe₂P/reduced graphene oxide/Fe₂P sandwich-structured nanowall arrays: a high-performance non-noble-metal electrocatalyst for hydrogen evolution

Abstract

Vertical sandwich-like architectures of Fe2P@rGO were constructed and performed well in terms of excellent HER activity and high stability simultaneously.

Hierarchically Porous W‐Doped CoP Nanoflake Arrays as Highly Efficient and Stable Electrocatalyst for pH‐Universal Hydrogen Evolution

“…Among these materials, transition metal phosphides (TMPs) such as MoP 2 , WP 2 , FeP 2 , FeP, Ni 2 P, CoP, and so on, have received growing attention as promising HER electrocatalysts because of their intrinsic catalytic property, high electrochemical stability and low cost. Nonetheless, the electrocatalytic performances of TMPs‐based materials cannot fully meet the requirement of practical applications, due to the relatively slow charge transportation and lack of exposed active sites .…”

Fe@Fe2P Core‐Shell Nanorods Encapsulated in Nitrogen Doped Carbon Nanotubes as Robust and Stable Electrocatalyst Toward Hydrogen Evolution

“…Meanwhile, the specific activity estimated from the normalization of LSV curve with ESA shown in Figure S7 also suggested that Fe@Fe 2 P/ NCNT exhibited higher intrinsic activity compared to Fe/NCNT electrocatalyst. [30] Meanwhile, Fe@Fe 2 P/NCNT electrocatalyst exhibited considerably high HER activity compared to Fe 2 P/RGO/Fe 2 P (101 mV), [23] Fe 2 P/GCS (88 mV) [26c] and Fe 2 P/GC (76 mV) [31] electrocatalysts. [28] NCNT and Fe@Fe 2 O 3 /NCNT with Tafel slopes of 179.1 mV dec À 1 and 151 mV dec À 1 manifested the sluggish HER kinetics due the few active sites for HER.…”

Graphene-modified nickel foam electrode for cathodic degradation of nitrofuranzone: Kinetics, transformation products and toxicity

“…The GR-Ni foam had a smaller semicircle diameter than bare Ni foam, indicating that the introduction of GR increased conductivity and promoted electron transfer [32,33]. Additionally, cyclic voltammetry (CV) can determine the double layer capacitance (Cdl) which is linearly proportional to effective active surface area [34,35]. The CV current responses for the Ni foam and GR-Ni foam electrodes in the region from -0.15 to -0.05 V vs. SCE should be mostly due to the charging of the double layer ( Figure S1a and b).…”
