Abstract

A novel sol-gel process of preparation of oxide electrocatalysts is investigated to prepare Ni-containing mixed oxides LaNiO{sub 3} and NiCo{sub 2}O{sub 4} at moderate temperatures. High surface area (20-55 m{sup 2} g{sup {minus}1}) powders and high roughness electrodes (30-1500) were obtained. Apparent and real electrocatalytical activity are compared and discussed.

Morphology Control of Carbon-Free Spinel NiCo ₂ O ₄ Catalysts for Enhanced Bifunctional Oxygen Reduction and Evolution in Alkaline Media

Journal Article Devaguptapu, Surya V. ; Hwang, Sooyeon ; Karakalos, Stavros ; ... - ACS Applied Materials and Interfaces

Spinel NiCo ₂O ₄ is considered a promising precious metal-free catalyst that is also carbon-free for oxygen electrocatalysis. Current efforts mainly focus on optimal chemical doping and substituent to tune its electronic structures for enhanced activity. Here, we study its morphology control and elucidate the morphology-dependent catalyst performance for bifunctional oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). Three types of NiCo ₂O ₄ catalysts with significantly distinct morphologies were prepared using temple-free, Pluronic-123 (P-123) soft, and SiO ₂ hard templates, respectively, via hydrothermal methods following by a calcination. While the hard-template yields sphere-like dense structures, soft-template assists themore »« less

Generalizable, Electroless, Template-Assisted Synthesis and Electrocatalytic Mechanistic Understanding of Perovskite LaNiO ₃ Nanorods as Viable, Supportless Oxygen Evolution Reaction Catalysts in Alkaline Media

Journal Article McBean, Coray L. ; Liu, Haiqing ; Scofield, Megan E. ; ... - ACS Applied Materials and Interfaces

We present that the oxygen evolution reaction (OER) is a key reaction for water electrolysis cells and air-powered battery applications. However, conventional metal oxide catalysts, used for high-performing OER, tend to incorporate comparatively expensive and less abundant precious metals such as Ru and Ir, and, moreover, suffer from poor stability. To attempt to mitigate for all of these issues, we have prepared one-dimensional (1D) OER-active perovskite nanorods using a unique, simple, generalizable, and robust method. Significantly, our work demonstrates the feasibility of a novel electroless, seedless, surfactant-free, wet solution-based protocol for fabricating “high aspect ratio” LaNiO ₃ and LaMnO ₃more »« less

Preparation of nickel aluminum-manganese spinel oxides Ni{sub x}Al{sub 1{minus}x}Mn{sub 2}O{sub 4} for oxygen electrocatalysis in alkaline medium: Comparison of properties stemming from different preparation methods

Journal Article Ponce, J ; Rios, E ; Gautier, J L ; ... - Journal of Solid State Chemistry

Two different procedures were used to prepare spinel-type Ni{sub x}Al{sub 1{minus}x}Mn{sub 2}O{sub 4} (0 {le} x {le} 1) compounds to study the effects of solid state properties of mixed oxides on their electrocatalytic properties. The oxalic route, coprecipitation of metal oxalates dissolved in propanol or ethanol, and the propionic route, hydrolysis of metal carboxylates in propionic acid, have been used. In both routes, thermal decomposition produces the corresponding oxides. X-ray diffraction patterns showed that the oxides crystallize in a cubic spinel phase with a unit cell parameter a that increases as aluminum is replaced by nickel. At low x values,more »« less

Tuning oxygen electrocatalysis via strain on LaNiO ₃(001)

Journal Article Yuk, Simuck F. ; Cooper, Valentino R. - Physical Chemistry Chemical Physics. PCCP (Print)

Theoretical insights into the influence of strain on the mechanisms of the oxygen evolution and oxygen reduction reactions on LaNiO ₃(001). The slow kinetics of the oxygen evolution (OER) and oxygen reduction (ORR) reactions hamper the development of renewable energy storage and conversion technologies. Transition-metal oxides (TMOs) are cost-effective replacements to conventional noble metal catalysts for driving these electrochemical systems. Strain is known to greatly affect the electronic structure of TMO surfaces, leading to significant changes in their electrocatalytic activities. In this study, we explore the influence of strain on the OER and ORR mechanisms on the LaNiO ₃(001) surfacemore » using density functional theory (DFT).« less

Template induced sol-gel synthesis of highly ordered LaNiO{sub 3} nanowires

Journal Article Zhi, Yang ; Yi, Huang ; Bin, Dong ; ... - Journal of Solid State Chemistry

The highly ordered LaNiO{sub 3} nanowires of the rare-earth perovskite-type composite oxide were controlled synthesized within a porous anodic aluminum oxide (AAO) template by means of sol-gel method using nitrate as raw materials and citric acid as chelating agent. The results of scanning electron microscopy (SEM) and transmission electron microscopy (TEM) revealed that the obtained LaNiO{sub 3} nanowires had a uniform length and diameter, which were determined by the thickness and the pore diameter of the applied AAO template. The results of X-ray diffraction (XRD) and the selected-area electron diffraction (SAED) indicated that the LaNiO{sub 3} nanowires were perovskite-type crystallinemore »« less
