N-doping can endow carbon materials with high electrochemical activity. Besides the widely validated sp2-hybridized nitrogen doping, sp-hybridized nitrogen (sp-N) atoms are also expected to be new active sites. However, both sp-N atoms and cyano (CN)…
Multi-component hollow structures with attractive physicochemical properties, often show superior electrochemical performance in alkali-ion batteries. Herein, a template-directed strategy is proposed for synthesis of multi-component hollow nanosphere…
Layered MoSe2 with a large interlayer has been regarded as an attractive host for larger-sized Na+/K+ ions. Nevertheless, serious volume effects and aggregation trends upon cycling are still great challenges for sodium-ion batteries (SIBs) and…
Nitrogen-doped carbon materials with abundant defects and strong potassium adsorption ability have been recognized as potential anodes for potassium ion batteries (PIBs). However, the limited content and uncontrolled type of nitrogen-doped sites…
N-doped TiO2/ reduced graphene oxide (N/TiO2/rGO) composite was prepared and used together with the commercial TiO2 for comparative research on photocatalytic degradation of crude oil in seawater. Five test conditions were designed including a…
