In this work, a honeycomb-like ZnO/SnO2 nanocomposite was synthesized on nickel foam (NF) using a single-step hydrothermal route for achieving good electrochemical performance. The as-prepared electrode showed an excellent electrochemical performance in 3 M KOH electrolyte, a superior specific capacitance (C-s) of 2307 F g(-1) and good stability, 7...

LiNi0.8Co0.1Mn0.1O2 (NCM811) has a high potential for using as the cathode material for lithium-ion batteries (LIBs) for electric vehicles owing to its high energy density and low cost. However, its poor rate capability and cycling performance have significantly hindered its application. In this study, we successfully design a uniform magnesium oxi...

Developing metal-free catalysts with high catalytic activity for oxygen evolution reaction (OER) is essentially important for energy and environment-related techniques. Compared with individual element doping, doping carbon materials with multiple heteroelements has more advantages for enhancing the OER performance. However, doped sites for the dif...
Graphene family nanomaterials (GFNs) have experienced significant development in recent years and have been used in many fields. Despite the benefits, they bring to society and the economy, their potential for posing environmental and health risks should also be considered. The increasing release of GFNs into the ecosystem is one of the key environ...

Ordered mesoporous WO3 nanocrystals have been successfully synthesized by a hydrothermal method using mesoporous silica of KIT-6 as a template and phosphotungstic acid as a precursor of WO3. The structure, morphology, and specific surface of WO3 nanocrystals were systematically characterized by XRD, SAXS, HR-TEM, and BET. To improve the sensing pro...
