K-ion batteries (KIBs) are now drawing increasing research interest as an inexpensive alternative to Li-ion (LIBs). However, due the large size of K+, stable electrode materials capable sustaining repeated K+ intercalation/deintercalation cycles extremely deficient especially if a satisfactory reversible capacity is expected. Herein, we demonstrated that structural engineering carbon into hollow interconnected architecture, shape similar neuron-cell network, promised high conceptual and...

Hollow nanostructures of metal oxides have found broad applications in different fields. Here, we reported a facile and versatile synthetic protocol to prepare hollow oxide nanospheres by modulating the chemical properties solid nanoparticles. Our synthesis design starts with precipitation urea-containing oxalate, which is soluble water but exists as ethanol. A controlled particle hydrolysis achieved through heating-induced urea decomposition, transforms composition an outside-to-inside...
Ammonia-borane (NH3·BH3; AB) has been considered as an excellent chemical material for hydrogen storage. However, developing highly efficient catalysts continuous generation from AB is still a challenge future fuel cell applications. The combination of Pt with Ni effective strategy to achieve active bimetallic nanocatalyst, and the particle size proved play crucial role in determining its final activity. synthesis PtNi catalyst dispersed clusters always challenge. In this report, PtNi/NiO...
Pt decorated CoCu bimetallic nanoparticles (NPs) coated by silica (Pt-CoCu@SiO2) were synthesized for efficient catalytic hydrogen production from hydrolysis of ammonia–borane (NH3·BH3; AB). Initially, silica-coated NPs (CoCu@SiO2) prepared a modified co-reduction method reverse microemulsion. Further, Pt-CoCu@SiO2 was obtained facile spontaneous displacement reaction using CoCu@SiO2 and H2PtCl6 as the starting materials. The activity on support compared to that monometallic supports, i.e.,...
Developing high‐performance, low‐cost, and robust electrocatalysts is of great importance to boost the efficiency oxygen evolution reaction (OER). Herein, based on integrated design chemical composition geometric structure, Fe‐doped CoO nanotubes (NTs) with high OER activity are prepared by a facile template‐free approach.

Hollow hybrid microspheres have found great potential in different areas, such as drug delivery, nanoreactors, photonics, and lithium-ion batteries. Here, we report a simple scalable approach to construct high-quality hollow through previously unexplored growth mechanism. Starting from uniform solid with low crystallinity, identified that hollowing process can happen the progressive inward crystallization initiated on particle surface: gradual encroachment of frontline toward core leads...
Layered sodium trititanate (Na2Ti3O7) is a promising anode material for sodium-ion batteries due to its suitable charge/discharge plateaus, cost-effectiveness, and eco-friendliness. However, slow Na+ diffusion kinetics, poor electron conductivity, instability during cycling pose significant challenges practical applications. To address these issues, we developed template-free method synthesize Na2Ti3O7-C hollow microspheres. The synthesis began with polymerization-induced colloid aggregation...
A surface doping strategy is demonstrated for the stabilization of LiMn2O4, which achieved by solid reaction between LiMn2O4 particle and its ZnO nanoshell. The treated sample shows a much improved high temperature performance with evidently suppressed Mn dissolution.
Pd nanoparticles were successfully introduced into the channels of mesoporous silica MCM-41 with their dispersion well-tuned. We identified dual role played by CTAB, which was critical for both micelle template and grafting, leading to formation a highly active Pd-MCM-41 nanocomposite catalysing Suzuki reaction.

Metal-ion batteries, especially lithium-ion batteries (LIBs), sodium-ion (SIBs), and potassium-ion (PIBs), have emerged as promising electronic devices for energy conversion storage. To satisfy the upsurging demand high density, cathode materials determining component in battery system are driven to deliver higher capacities by either extracting more active metal ions (Li+, Na+, K+) or increasing operating voltage. However, serious side reactions of cathodes will occur, leading severe...
