Abstract

The phases formed by alkaline precipitation of Ni(OH)₂ at different temperatures and different levels of carbonate and nitrate anions have been characterized by X-ray diffraction, elemental analysis, FTIR spectroscopy, TG-MS, N₂ physisorption and cyclic voltammetry. The dehydration-deanionization of α- to β-Ni(OH)₂ passes through an interstratified intermediate IS-Ni(OH)₂, which can be stabilized at 80 °C in the presence of carbonates. IS-Ni(OH)₂ materials have been prepared with CO₃²⁻/Ni²⁺ ratio ranging from 0.05 to 0.16, resulting in different ratios of interstratified α and β phase layers. IS-Ni(OH)₂, thermally stable up to 200 °C, presents a peculiar ink-bottle mesoporosity and surface area higher than 100 m² g⁻¹. The material is promising for electrocatalytic applications on the basis of the textural properties and a reproducible reduction potential of 0.37 V versus SCE. The easily reversible reducibility of Ni²⁺ is also shown by the TG-MS of the thermal dehydroxylation-deanionization to NiO, evidencing transient Ni³⁺ species formed by reaction with NO_x emitted from the decomposition of nitrates.

期刊介绍： The Journal of Materials Science publishes reviews, full-length papers, and short Communications recording original research results on, or techniques for studying the relationship between structure, properties, and uses of materials. The subjects are seen from international and interdisciplinary perspectives covering areas including metals, ceramics, glasses, polymers, electrical materials, composite materials, fibers, nanostructured materials, nanocomposites, and biological and biomedical materials. The Journal of Materials Science is now firmly established as the leading source of primary communication for scientists investigating the structure and properties of all engineering materials.
