The design and synthesis of hierarchical micro-nano structures of transition metal oxides have played an essential role in the supercapacitor field. In this work, in situ three-dimensional construction of nanoporous cobalt oxide (Co3O4) has been derived from the metal-organic framework (MOF) distributed evenly in electrospun polyacrylonitrile nanof...

Covalent Organic Frameworks (COFs), an emerging class of crystalline porous materials, are a new type of support for grafting lanthanide ions (Ln3+), which can be employed as ratiometric luminescent thermometers. In this work we have shown that COFs co-grafted with lanthanide ions (Eu3+, Tb3+) and Cu2+ (or potentially other d-metals) can synchronou...
The design of the cost-effective, efficient, and durable electrocatalysts for hydrogen evolution reaction (HER) is of great importance in the field of clean and renewable energies. In this study, Ni/NiO nanocomposite supported on N-doped carbon nanoweb (Ni/NiO/NCW) hybrid materials are proposed as an efficient electrocatalyst for HER in alkaline me...
The growing demand for portable and flexible electronics, such as roll-up displays, electronic papers, and wearable sensing devices, has stimulated the development of flexible energy storage devices. Herein, we demonstrate the fabrication of a high-voltage solid-state flexible free-standing supercapacitor with an ionogel separator. The negative ele...

One-dimensional (1D) hybrid nanostructures composed of silver/silver sulfide (Ag/Ag2S) and zinc sulfide (ZnS) were prepared by controllable migration of Ag species from the Ag nanowire (NW) core into the ZnS nanosheet shell. This Ag diffusion process can be manipulated by different concentrations of sulfur (thiourea) to realize various interspersio...

ZnCo2O4 as an electrode material for supercapacitors has been extensively investigated owing to its unique structural characteristics and high capacitance. However, the conductivity still cannot reach the level of the industrialization. In order to solve this problem, it is an efficient strategy to develop composed electrode materials. Here, we pre...
