Although lead halide perovskites are demonstrated to be promising photocatalysts for hydrogen evolution from splitting, it still remains challenging fabricate efficient and stable catalysts. Here MoS2 nanoflowers with abundant active sites assembled methylammonium iodide (MAPbI3) microcrystals form a new heterostructure. Its rate can reach up about 30 000 μmol g–1 h–1, which is more than 1000-fold higher pristine MAPbI3 under visible light irradiation (λ ≥ 420 nm). Importantly, the solar HI...
Lithium-ion batteries that utilize polyethylene (PE) separators still require improvement. To improve the electrochemical properties and thermal stability of PE separators, an-ultrathin Al2O3 layer (∼10 nm) was precisely coated onto surface a 7 μm thick separator via atomic deposition. The resulting ultrathin ALD-PE exhibited excellent dimensional flexibility, tensile strength considerably improved. Moreover, demonstrated better electrolyte wettability, higher ionic conductivity, lower...
The reverse water–gas shift (RWGS) reaction is a critical step for adjusting the CO/H2 ratio in crude syngas via CO2 hydrogenation chemical industry. Generally, conditioning of competitively occurs two different pathways at moderate temperature range (350–450 °C), such as RWGS (CO2 + H2 → CO H2O) and methanation 4H2 CH4 2H2O). In this study, we demonstrate that interfacial synergy Ni/Ga2O3 can boost selective to (CO selectivity >95%) 350–450 °C. Detailed investigations indicate interface...
The poly (ethylene oxide) (PEO) solid polymer electrolytes suffer from narrow electrochemical stability window and cannot match high voltage lithium cobalt oxide (LCO) cathode. Herein, an ultrathin Al2O3 nanolayer was uniformly deposited on the surface of LCO via powder atomic layer deposition (PALD) to realize electrolyte cycling stability. PEO contains 20 % (w/w) difluoro(oxalate)borate (LiDFOB) 7.5 titanium aluminum phosphate (LATP) with cellulose nonwoven as a support substrate....
Abstract Polyvinylidene fluoride (PVDF) has unique electrochemical oxidation resistance and is the only binder for high‐voltage cathode materials in battery industry a long time. However, PVDF still some drawbacks, such as environmental limitations on fluorine, strict requirements humidity, weak adhesion, poor lithium ion conductivity. Herein, long‐standing issues associated with cobalt oxide (LiCoO 2 ; LCO) are successfully addressed by incorporating phenolphthalein polyetherketone (PEK‐C)...
Abstract Butadiene (BD) is a critical raw material in chemical industry, which conventionally produced from naphtha cracking. The fast‐growing demand of BD and the limited oil reserve motivate chemists to develop alternative methods for production. Shale gas, mainly consists light alkanes, has been considered as cheap materials replace production via n ‐butane direct dehydrogenation ( ‐BDH). However, quest highly‐efficient catalysts ‐BDH driven by current drawback low selectivity. Here, we...
