2D metal chalcogenides (MCs) have garnered significant attention from both scientific and industrial communities due to their potential in developing next‐generation functional devices. Vapor‐phase deposition methods have proven highly effective in fabricating high‐quality 2D MCs. Nevertheless, the conventionally high thermal budgets required for synthesizing 2D MCs pose limitations, particularly...
Metallic sodium is regarded as the most potential anode for sodium‐ion batteries due to its high capacity and earth‐abundancy. Nevertheless, uncontrolled Na dendrite growth and infinite volume change remain great challenges for developing high‐performance sodium metal batteries. This work provides a simple and general approach to stabilize sodium metal anode (SMA) by constructing Sn nanoparticles‐anchored...
Design and development of low‐cost and highly efficient non‐precious metal electrocatalysts for hydrogen evolution reaction (HER) in an acidic medium are key issues to realize the commercialization of proton exchange membrane water electrolyzers. Ni is regarded as an ideal alternative to substitute Pt for HER based on the similar electronic structure and low price as well. However, low intrinsic activity...
Solid catalyst is widely recognized as an effective strategy to control the chirality of single‐walled carbon nanotubes (SWNTs). However, it is still not compatible with high density in horizontal arrays. “Trojan” catalysts strategy is one of the most effective methods to realize SWNTs with high density and has great potential in chirality control. Here, the co‐realization of high density and chirality...
Construction of 2D graphic carbon nitrides (g‐CNx) with wide visible light adsorption range and high charge separation efficiency concurrently is of great urgent demand and still very challenging for developing highly efficient photocatalysts for hydrogen evolution. To achieve this goal, a two‐step pyrolytic strategy has been applied here to create ultrathin 2D g‐CNx with extended the π‐conjugation...
Tellurium (Te) is a promising electrode active material for potassium‐ion batteries due to its intrinsic electrical conductivity and ultra‐high theoretical volumetric capacity. Nevertheless, Te‐based electrodes usually exhibit low capacity at high rates and poor cycling stability caused by the large volume expansion and severe polytellurides dissolution. Herein, hierarchical porous carbon nanofibers...
With the rapid development of anion‐exchange membrane technology and adequate supply of high‐performance non‐noble metal oxygen reduction reaction (ORR) catalysts in alkaline media, the commercialization of anion exchange membrane fuel cells (AEMFCs) become possible. However, the kinetics of the anodic hydrogen oxidation reaction (HOR) in AEMFCs is significantly decreased compared to the HOR in proton...
In the preparation of nanomaterials, the kinetics and thermodynamics in the reaction can significantly affect the structures and phases of nanocrystals. Therefore, people are keen to adopt various synthetic strategies to accurately assemble the target nanocrystals, and reveal the underlying mechanism of the formation of specific structures. In this work, the total reaction time is adjusted to let...
To further increase the energy and power densities of lithium‐ion batteries (LIBs), monoclinic Li3V2(PO4)3 attracts much attention. However, the intrinsic low electrical conductivity (2.4 × 10−7 S cm−1) and sluggish kinetics become major drawbacks that keep Li3V2(PO4)3 away from meeting its full potential in high rate performance. Recently, significant breakthroughs in electrochemical performance...
