Transition metal oxides (TMOs) have attracted considerable attention owing to their strong anchoring ability and natural abundance. However, their single‐site adsorption toward sulfur (S) species significantly lowers the possibility of S species reacting with Li+ in the electrolyte and increases the reaction barrier. This study investigates molecular modification by coupling the TMO structure with...
Lithium–Sulfur Batteries
In article number 2206750, Kisoo Yoo, Jong‐Hoon Kim, Hengyue Xu, and co‐workers report a hybrid organic‐inorganic vanadyl ethylene glycolate as a novel carbon‐free cathode material for lithium‐sulfur battery. The dual‐site adsorption and fast electron/ion transport enable high anchoring efficiency and catalytic activity during the polysulfides conversion. Accordingly, excellent...
Electrochemical preparation/processing of functional silicon from abundant silica is an ideal protocol to promote sustainability of energy sectors. Such an imperative task is challenged by poor electrical conductivity of Si/SiO2 and inadequate mass diffusion of bulk silicon. Herein, a template‐free and one‐step preparation of silicon nanotubes (Si‐NT) from electrochemical reduction of silica in molten...
The 1,3‐conjugated diynes are an important class of chemical intermediates, and the selective crosscoupling of terminal alkynes is an efficient chemical process for manufacturing asymmetrical 1,3‐conjugated diynes. However, it often occurs in homogenous conditions and costs a lot for reaction treatment. Herein, a copper catalyzed strategy is used to synthesize highly ordered mesoporous nitrogen‐doped...
Ni‐rich layered oxides are significantly promising cathode materials for commercial high‐energy‐density lithium‐ion batteries. However, their major bottlenecks limiting their widespread applications are capacity fading and safety concerns caused by their inherently unstable crystal structure and highly reactive surface. Herein, surface structure and bulk charge regulation are concurrently achieved...
Gold nanorods (Au NRs) have attracted great attention owing to their significant role in catalysis, imaging, and photothermal therapy. The internal atomic structure control of metallic NRs has long been a challenge. In article number 2001101, Jianfeng Yan and co‐workers demonstrate the concept of internal atomic structures tailored with light, and Au NRs with various internal atomic structure are...
Laser processing of gold nanorods (Au NRs) relying on light–matter interaction provides great opportunities in various potential applications. Unveiling the light‐induced structure change is a crucial goal in order to control the shape and related properties for practical application. However, the internal atomic structure control of metallic NRs has long been a challenge. Here, the concept of internal...
