As one of the most promising candidates for supercapacitor electrodes, transition metal hydroxides usually suffer from quick decay in capacity during cycling, mainly caused by decrease electroactive surface area resulting instability microstructure/morphology upon fast and repeated charging/discharging. Herein, we fabricated a structure-stable Ni(OH)2 grown on Ni foam via situ ion-exchange reaction with Mg(OH)2 as sacrificial substrate effective dopant. The obtained hybrid possesses...
A set of identical Co3O4 nanosheets with different oxygen vacancy amounts are rationally designed by varied reduction treatments and comparison their properties. Remarkably, the oxygen-vacancy-rich (OVR-Co3O4 NSs) exhibit excellent electrochemical performance for potential use as a promising candidate next generation supercapacitors.
A novel leaven dough method was developed to prepare three-dimensional Ni foams, upon which a thin NiO nanostructure grown through thermal oxidation form NiO/Ni foams as highly efficient electrocatalyst for oxygen evolution reactions (OER).

Flower-like hierarchical mesoporous carbon superstructures (FMCS), fabricated by one-pot hydrothermal reaction, exhibit outstanding supercapacitive performances.
With the rapid growth of biodiesel production in recent years, it is essential to evaluate thermal degradation characteristics and its feedstock oil, for they are concerned with plenty scientific applications. This study investigates oil through thermogravimetric analysis conjunction Fourier transform infrared spectroscopy (TGA–FTIR). The experiments conducted under inert conditions from 298 873 K, operated at temperature heating rates 5, 10, 15, 20 K min–1. Based on TGA results, activation...
Facet engineering of oxide nanocrystals represents a powerful method for generating diverse properties practical and innovative applications. Therefore, it is crucial to determine the nature exposed facets oxides in order develop facet/morphology-property relationships rationally design nanostructures with desired properties. Despite extensive applications electron microscopy visualizing facet structure nanocrystals, volumes sampled by such techniques are very small may not be representative...

Abstract Separation membranes with homogeneous charge channels are the mainstream to reject charged mass by forming electrical double layer (EDL). However, EDL often compresses effective solvent transport space and weakens channel‐ion interaction. Here, built‐in electric fields (BIEFs) constructed in lamellar assembling heterostructured nanosheets, which contain alternate positively‐charged nanodomains negatively‐charged nanodomains. We demonstrate that BIEFs perpendicular horizontal channel...
Abstract Radiation‐resistant nanoporous adsorbent that can realize absolute CO 2 /Xe (Kr) separation without Xe and Kr loss is crucial, but yet to be achieved for accurate reliable nuclear fuel burnup analysis.
