Three‐dimensional Antimony Sulfide Based Flat Optics

Advanced Functional Materials, EarlyView.
This work presents the development of a grayscale electron beam lithography (g‐EBL) method for fabricating antimony trisulfide (Sb2S3) nanostructures with customizable 3D profiles. The refractive index of g‐EBL patterned Sb2S3 is determined based on the synergy of genetic algorithm and transfer matrix method.

Size Dependent Fast Li Ion Storage Based on Size Regulated TiO2(B) Nanosheet Electrodes with Vertical, Horizontal and Random Alignment

Electrochemistry, 2020
TiO2(B) has a high theoretical capacity of 335 mAh g−1 for Li+ intercalation and thus has been considered as a candidate for lithium-ion capacitor and Li-ion battery negative electrodes. For high rate lithium storage, i.e.

Intrabandgap States Engineering in Functionalized Nanodiamond to Generate Solvated Electrons for Photocatalysis Under Solar Illumination

Advanced Functional Materials, EarlyView.
The negative electron affinity of diamond allows to emit highly reductive electrons. By introducing intra‐bandgap states and an optimized electron transfer mechanism by surface functionalization with Ru(bpy)3, the formation of solvated electrons is achieved upon solar irradiation.

Silver Ion‐Mediated [hk1]‐Oriented Sb2Se3 Crystal Growth for Efficient Photoelectrochemical Hydrogen Evolution

Advanced Functional Materials, EarlyView.
Ag+‐mediated hydrothermal crystal engineering promotes preferential [hk1]‐oriented growth of Sb2Se3 via an ultrathin MoOx interlayer, improving crystallinity and suppressing non‐radiative recombination. The optimized Ag+ treatment photocathode delivers 24.7 mA cm−2 at 0 VRHE and improved stability, revealing an ion‐modulated route to high‐performance ...
