Hydrothermal synthesis of needle-like hyperbranched Ni(SO4)0.3(OH)1.4 bundles and their morphology-retentive decompositions to NiO for lithium storage

Tailoring NiO Nanostructured Arrays by Sulfate Anions for Sodium‐Ion Batteries

“…This diffraction contrast possibly attributes to the irradiation damage under high‐energy electron beam. This phenomenon has also been observed by other researchers,[7a,15] which is likely ascribed to the sensitivity of hydroxide species subjected to the electron‐beam irradiation during TEM observations. The high‐resolution TEM (HRTEM) image shown in Figure S5c (Supporting Information) further reveals there are defect sites (marked with red circles) dispersed between the discontinuous lattice fringes.…”

“…The SAED pattern (the inset of Figure i) shows bright diffraction spots along the [001] zone axis, indicating the attached nanoparticle subunits have a relatively ordered orientation and it is the same with the supporting nanosheet. [15b]…”

A Venture Synthesis and Fabrication of BiVO4 as a Highly Stable Anode Material for Na‐Ion Batteries

“…The prepared material indicates many nanoparticles fused and growing on one direction to forms on needles like hyperbranched bundles. The observed needles like hyperbranched bundles morphology was similar to the previous report of Ni(SO 4 ) 0.3 (OH) 1.4 . It was observed well dispersion in large quantity of needles.…”

Ultrathin sulfate-intercalated NiFe-layered double hydroxide nanosheets for efficient electrocatalytic oxygen evolution

“…At the elevated temperatures, the gradual hydrolysis of the acetate anions and the release of OH À ions ensured a slow reaction between metal ions with OH À , thereby controlling nuclei formation and subsequent crystal growth to allow uniform precipitation. 39 Sulfate plays a key role in the formation of ultrathin nanosheets. The size of the intercalated tetrahedral SO 4 2À allowed an increase of the interlayer spacing compared to that of CO 3 2À .…”
