Perovskite oxides exhibit potential for use as electrocatalysts in the oxygen evolution reaction (OER). However, their low specific surface area is main obstacle to realizing a high mass-specific activity that required be competitive against state-of-the-art precious metal-based catalysts. We report enhanced performance of Ba0.5Sr0.5Co0.8Fe0.2O3-δ (BSCF) OER with intrinsic significantly higher than benchmark IrO2, and this result was achieved via fabrication an amorphous BSCF nanofilm on...
The practical application of aqueous zinc-ion batteries (AZIBs) is greatly challenged by rampant dendrites and pestilent side reactions resulting from an unstable Zn–electrolyte interphase. Herein, we report the construction a reliable superstructured solid electrolyte interphase for stable Zn anodes using mesoporous polydopamine (2D-mPDA) platelets as building blocks. shows biomimetic nacre's "brick-and-mortar" structure artificial transmembrane channels hexagonally ordered mesopores in...

Gas sensors based on hybrid materials of graphene oxide/metal oxide semiconductors are an effective way to improve sensor performance. In this paper, we demonstrate a high-performance nitric (NO) gas nitrogen-doped reduced oxide/ZnO nanocrystals (N-rGO/ZnO) operating at low work temperature. ZnO nanocrystals, with average size approximately 5 nm, can be uniformly and compactly anchored the surface N-rGO using facile two-step hydrothermal synthesis appropriate amount ammonia as nitrogen...
Passivating contacts that simultaneously promote carrier selectivity and suppress surface recombination are considered as a promising trend in the crystalline silicon (c-Si) photovoltaic industry. In this work, efficient p-type c-Si (p-Si) solar cells with cuprous oxide (Cu2O) hole-selective demonstrated. The direct p-Si/Cu2O contact leads to substoichiometric SiOx interlayer diffusion of Cu into substrate, which would generate deep-level impurity behaving centers. An Al2O3 layer is...

Aqueous zinc batteries (ZIBs) have attracted considerable attention in recent years because of their high safety and eco-friendly features. Numerous studies shown that adding Mn2+ salts to ZnSO4 electrolytes enhanced overall energy densities extended the cycling life Zn/MnO2 batteries. It is commonly believed additives electrolyte inhibit dissolution MnO2 cathode. To better understand role additives, ZIB using a Co3 O4 cathode instead 0.3 m MnSO4 + 3 built avoid interference from As...
We theoretically investigate the strong coupling of a topological photonic state (TPS) and Tamm plasmon polaritons (TPPs) in graphene embedded one-dimensional crystal (TPC)/Ag structure visible range. It is shown that interaction TPS at TPC heterointerface TPP Ag surface enables large Rabi splitting up to 96.8 meV with dual-narrow-band perfect absorption. A spectral linewidth hybrid mode can be 0.3 nm Q factor 1078. The numerical results also reveal either tuned by adjusting geometric...

The fabrication of van der Waals (vdWs) heterostructures mainly extends to two-dimensional (2D) materials. Nevertheless, the current processes for obtaining high-quality 2D films are exfoliated from their bulk counterparts or by high-temperature chemical vapor deposition (CVD), which limits industrial production and is often accompanied defects. Herein, we first fabricated type-II p-PdSe2/n-InSe vdWs heterostructure using ultra-high vacuum laser molecular beam epitaxy (LMBE) technique...
