Title: In Situ Growth of Ni ₂P–Cu ₃P Bimetallic Phosphide with Bicontinuous Structure on Self-Supported NiCuC Substrate as an Efficient Hydrogen Evolution Reaction Electrocatalyst

Abstract

A direct and effective approach is proposed to fabricate bimetallic phosphide Ni ₂P–Cu ₃P with controllable phase compn. and distribution for catalytic hydrogen evolution reaction (HER). Unlike previously reported precursors, a porous Ni-Cu alloy incorporated with graphitic carbon (NiCuC) prepd. via powder metallurgy is employed herein, and the generated Ni ₂P–Cu ₃P@NiCuC possesses a hierarchical porous structure and controllable phase compn. due to the high porosity and tunable Ni/Cu ratio of the precursor. With an optimal Cu content of 30.0 wt. %, the catalyst demonstrates the highest catalytic activity due to a synergistic interaction between different metallic phosphide sites and the facilitated mass transport. Meanwhile, d. functional theory (DFT) calcn. reveals that the at. interaction of Ni ₂P–Cu ₃P substantially lower the activation barrier for enhanced HER catalytic activity. Finally, the powder metallurgy provides an approach for the design of bimetallic phosphide electrocatalysts for HER and other catalytic applications.

Bimetallic Cobalt-Based Phosphide Zeolitic Imidazolate Framework: CoP _x Phase-Dependent Electrical Conductivity and Hydrogen Atom Adsorption Energy for Efficient Overall Water Splitting

Journal Article Song, Junhua ; Zhu, Chengzhou ; Xu, Bo Z. ; ... - Advanced Energy Materials

Cobalt-based bimetallic phosphide encapsulated in carbonized zeolitic imadazolate frameworks has been successfully synthesized and showed excellent activities toward both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). Density functional theory calculation and electrochemical measurements reveal that the electrical conductivity and electrochemical activity are closely associated with the Co2P/CoP mixed phase behaviors upon Cu metal doping. This relationship is found to be the decisive factor for enhanced electrocatalytic performance. Moreover, the precise control of Cu content in Co-host lattice effectively alters the Gibbs free energy for H* adsorption, which is favorable for facilitating reaction kinetics. Impressively, an optimized performance hasmore »« less

Hierarchical tri-functional electrocatalysts derived from bimetallic–imidazolate framework for overall water splitting and rechargeable zinc–air batteries

Journal Article Ahn, Sung Hoon ; Manthiram, Arumugam - Journal of Materials Chemistry. A

There is a growing need for an efficient multi-functional electrocatalyst that can produce industry-level high currents at low overpotentials. In this article, we report a highly efficient, robust tri-functional catalytic electrode that simultaneously catalyzes three different electrochemical reactions: the oxygen evolution reaction (OER), hydrogen evolution reaction (HER), and oxygen reduction reaction (ORR). The catalytic electrodes with a hierarchical structure are converted from a hierarchical nickel-rich, nickel–cobalt bimetallic–imidazolate framework directly grown onto a nickel foam. Catalytic electrodes composed of bimetallic phosphides exhibit excellent OER and HER catalytic activity (an overpotential of 201/250 mV at 20/100 mA cm ^-2 for OER andmore »« less

Active Role of Phosphorus in the Hydrogen Evolving Activity of Nickel Phosphide (0001) Surfaces

Journal Article Wexler, Robert B. ; Martirez, John Mark P. ; Rappe, Andrew M. - ACS Catalysis

Optimizing catalysts for the hydrogen evolution reaction (HER) is a critical step toward the efficient production of H ₂(g) fuel from water. It has been demonstrated experimentally that transition-metal phosphides, specifically nickel phosphides Ni ₂P and Ni ₅P ₄, efficiently catalyze the HER at a small fraction of the cost of archetypal Pt-based electrocatalysts. However, the HER mechanism on nickel phosphides remains unclear. We explore, through density functional theory with thermodynamics, the aqueous reconstructions of Ni ₂P(0001) and Ni ₅P ₄(0001)/(000$$ \overline{1}\ $$), and we find that the surface P content on Ni ₂P(0001) depends on the applied potential, whichmore »« less

Cobalt phosphide based nanostructures as bifunctional electrocatalysts for low temperature alkaline water splitting

Journal Article Lambert, Timothy N. ; Vigil, Julian A. ; Christensen, Ben - ECS Transactions (Online)

Cobalt phosphide based thin films and nanoparticles were prepared by the thermal phosphidation of spinel Co ₃O ₄ precursor films and nanoparticles, respectively. CoP films were prepared with overall retention of the Co ₃O ₄ nanoplatelet morphology while the spherical/cubic Co ₃O ₄ and Ni _0.15Co _2.85O ₄ nanoparticles were converted to nanorods or nanoparticles, respectively. The inclusion of nickel in the nanoparticles resulted in a 2.5 fold higher surface area leading to higher gravimetric performance. In each case high surface area structures were obtained with CoP as the primary phase. All materials were found to act as effective bifunctionalmore »« less

Directed surfaces structures and interfaces for enhanced electrocatalyst activity, selectivity, and stability for energy conversion reactions

Technical Report Jaramillo, Thomas F.

In this project, we have employed a systematic approach to develop active, selective, and stable catalyst materials for important electrochemical reactions involving energy conversion. In particular, we have focused our attention on developing active catalyst materials for the hydrogen evolution reaction (HER), oxygen evolution reaction (OER) and oxygen reduction reaction (ORR). HER: We have synthesized and investigated several highly active and acid stable non-precious metal HER catalysts, including: [Mo ₃S ₁₃] ^2- nanoclusters (Nature Chemistry, 2014) and molybdenum phosphosulfide (MoP|S) (Angewandte Chemie, 2014). We have also aimed to engineer these catalyst formulations in a membrane electrode assembly (MEA) for fundamentalmore »« less
