A Multisite Strategy for Enhancing the Hydrogen Evolution Reaction on a Nano‐Pd Surface in Alkaline Media

Advanced Energy Materials (2017)

Hanbin Liao Chao Wei Jingxian Wang Adrian C. Fisher Thirumany Sritharan

Abstract The hydrogen evolution reaction (HER) on a noble metal surface in alkaline media is more sluggish than that in acidic media due to the limited proton supply. To promote the reaction, it is necessary to transform the alkaline HER mechanism via a multisite catalyst, which has additional water dissociation sites to improve the proton supply to an optimal level. Here, this study reports a top‐down strategy to create a multisite HER catalyst on a nano‐Pd surface and how to further fine‐tune the areal ratio of the water dissociation component to the noble metal surface in core/shell‐structured nanoparticles (NPs). Starting with Pd/Fe 3 O 4 core/shell NPs, electrochemical cycling is used to tune the coverage of iron (oxy)hydroxide on a Pd surface. The alkaline HER activity of the core/sell Pd/FeO x (OH) 2−2 x NPs exhibits a volcano‐shaped correlation with the surface Fe species coverage. This indicates an optimum coverage level where the rates of both the water dissociation step and the hydrogen formation step are balanced to achieve the highest efficiency. This multisite strategy assigns multiple reaction steps to different catalytic sites, and should also be extendable to other core/shell NPs to optimize their HER activity in alkaline media.

Shifting Oxygen Charge Towards Octahedral Metal: A Way to Promote Water Oxidation on Cobalt Spinel Oxides

Angewandte Chemie (2019)

Shengnan Sun Yuanmiao Sun Ye Zhou Shibo Xi Xiao Ren

Abstract Cobalt spinel oxides are a class of promising transition metal (TM) oxides for catalyzing oxygen evolution reaction (OER). Their catalytic activity depends on the electronic structure. In a spinel oxide lattice, each oxygen anion is shared amongst its four nearest transition metal cations, of which one is located within the tetrahedral interstices and the remaining three cations are in the octahedral interstices. This work uncovered the influence of oxygen anion charge distribution on the electronic structure of the redox‐active building block Co−O. The charge of oxygen anion tends to shift toward the octahedral‐occupied Co instead of tetrahedral‐occupied Co, which hence produces strong orbital interaction between octahedral Co and O. Thus, the OER activity can be promoted by pushing more Co into the octahedral site or shifting the oxygen charge towards the redox‐active metal center in CoO 6 octahedra.

Surface Segregation in Bimetallic Nanoparticles: A Critical Issue in Electrocatalyst Engineering

Small (2015)

Hanbin Liao Adrian C. Fisher Zhichuan J. Xu

Bimetallic nanoparticles are a class of important electrocatalyst. They exhibit a synergistic effect that critically depends on the surface composition, which determines the surface properties and the adsorption/desorption behavior of the reactants and intermediates during catalysis. The surface composition can be varied, as nanoparticles are exposed to certain environments through surface segregation. Thermodynamically, this is caused by a difference in surface energy between the two metals. It may lead to the enrichment of one metal on the surface and the other in the core. The external conditions that influence the surface energy may lead to the variation of the thermodynamic steady state of the particle surface and, thus, offer a chance to vary the surface composition. In this review, the most recent and important progress in surface segregation of bimetallic nanoparticles and its impact in electrocatalysis are introduced. Typical segregation inducements and surface characterization techniques are discussed in detail. It is concluded that surface segregation is a critical issue when designing bimetallic catalysts. It is necessary to explore methods to control it and utilize it as a way towards producing robust, bimetallic electrocatalysts.

An Investigation on the Relationship between the Stability of Lithium Anode and Lithium Nitrate in Electrolyte

Journal of The Electrochemical Society (2019)

Linghui Yu Jiajia Song Luyuan Paul Wang Samuel Jun Hoong Ong Chengding Gu

Understanding the relationship between lithium anode and electrolyte is important to develop a more compatible lithium/electrolyte system for stable and safe cycling of lithium-metal based batteries. However, to date, there has not been any work to quantify the effects of electrolyte on the performance of electrode due to the complexity. Herein, we quantify the relationship between an electrolyte additive, LiNO3, and the stability of lithium anode. It is found that, with increasing the amount of LiNO3, the cyclability of lithium anode rises linearly and the risk of dendrite-induced short circuits can be reduced. Low Coulombic efficiency (CE) and short circuits tend to occur in tandem. LiNO3 is found to be continuously consumed upon electrochemical cycling, which leads to a low CE and a high risk of short circuits.

Understanding Fundamentals and Reaction Mechanisms of Electrode Materials for Na‐Ion Batteries

Small (2018)

Linghui Yu Luyuan Paul Wang Hanbin Liao Jingxian Wang Zhenxing Feng

Abstract Development of efficient, affordable, and sustainable energy storage technologies has become an area of interest due to the worsening environmental issues and rising technological dependence on Li‐ion batteries. Na‐ion batteries (NIBs) have been receiving intensive research efforts during the last few years. Owing to their potentially low cost and relatively high energy density, NIBs are promising energy storage devices, especially for stationary applications. A fundamental understanding of electrode properties during electrochemical reactions is important for the development of low cost, high‐energy density, and long shelf life NIBs. This Review aims to summarize and discuss reaction mechanisms of the major types of NIB electrode materials reported. By appreciating how the material works and the fundamental flaws it possesses, it is hoped that this Review will assist readers in coming up with innovative solutions for designing better materials for NIBs.

Bimetallic Nanoparticles: Surface Segregation in Bimetallic Nanoparticles: A Critical Issue in Electrocatalyst Engineering (Small 27/2015)

Small (2015)

Hanbin Liao Adrian C. Fisher Zhichuan J. Xu

Surface segregation is just like an invisible hand in bimetallic electrocatalysts, which has the potential to migrate atoms to the bimetallic nanoparticle surface. On page 3221, Z. J. Xu and co-workers explain how the external conditions that influence the surface energy may induce variation in the surface composition. It is of profound importance to control and utilize this as a way to produce superior bimetallic electrocatalysts.

Selective Electroreduction of Carbon Dioxide to Formic Acid on Cobalt‐Decorated Copper Thin Films

Small Methods (2019)

Chencheng Dai Libo Sun Jiajia Song Hanbin Liao Adrian C. Fisher

Abstract The development of highly efficient, selective, and economic approaches for electrochemical reduction of carbon dioxide to hydrocarbons is a promising way to promote the sustainable carbon cycle nowadays. Here, a stable cobalt‐decorated copper catalyst is reported with significantly enhanced selectivity toward formic acid produced from CO 2 through electrochemical reduction. This catalyst is prepared through the electrodeposition of cobalt on the surface of copper, followed by Ar and air atmosphere treatment. The as‐prepared catalyst exhibits selective conversion of CO 2 to formic acid with a Faradaic efficiency (FE) of ≈80% at an applied potential of −0.65 V versus reversible hydrogen electrode. Meanwhile, the copper electrode treated with the same conditions without cobalt decoration and the cobalt‐decorated copper electrode without Ar treatment process only show an FE toward formic acid of ≈56% and ≈57% from CO 2 reduction, respectively. This study represents a facile decoration method to prepare highly selective electrocatalysts for the efficient reduction of CO 2 to value‐added chemicals in aqueous electrolytes.
