Abstract Two‐dimensional (2D) transition‐metal carbides (MXenes) are widely adopted as potential electrocatalysts for the hydrogen evolution reaction (HER) owing to their metallic conductivity, rich tunable surface chemistry, and atomic thickness with highly exposed active sites. Previously published theoretical results indicate that MXenes functionalized entirely oxygen have lower Δ G H* HER. However, contain many terminal F groups on basal plane, which is detrimental Herein, development of...
Achieving homogeneous phase transition and uniform charge distribution is essential for good cycle stability high capacity when conversion materials are used as electrodes. Herein, we show that chemical lithiation of bulk 2H-MoS2 distorts its crystalline domains in three primary directions to produce mosaic-like 1T′ nanocrystalline domains, which improve uniformity during subsequent electrochemical conversion. 1T′-LixMoS2, a macroscopic dense material with interconnected nanoscale grains,...

Efficient and stable inorganic lead-free halide perovskites have attracted tremendous attention for next-generation solid-state lighting. However, single perovskite phosphors with strong, tunable-color-temperature white-light emission are rare.

Two-dimensional ferroelectrics is attractive for synaptic device applications because of its low power consumption and amenability to high-density integration. Here, we demonstrate that tin monosulfide (SnS) films less than 6 nm thick show optimum performance as a semiconductor channel in an in-plane ferroelectric analogue device, whereas thicker have much poorer response due screening effects by higher concentration charge carriers. The SnS exhibits behaviors with highly stable...
Lithium-sulfur (Li-S) batteries have attracted considerable attention over the last two decades because of a high energy density and low cost. However, wide application Li-S has been severely impeded due to poor electrical conductivity S, shuttling effect soluble lithium polysulfides (LiPSs), sluggish redox kinetics S species, especially under loading.
