The desire to exploit clean and sustainable energy sources with high gravimetric density has greatly inspired the exploration of hydrogen as an affordable alternative fossil energy. Electrocatalytic water splitting is efficient method for low‐cost production pure H 2 , but use platinum (Pt)‐like active electrocatalysts evolution reaction (HER) remains necessary. In attempts replace high‐value, scarce Pt catalysts, nickel‐based materials are being developed, earth‐abundant HER...
The practical application of Lithium–Sulfur batteries largely depends on highly efficient utilization and conversion sulfur under the realistic condition high‐sulfur content low electrolyte/sulfur ratio. Rational design heterostructure electrocatalysts with abundant active sites strong interfacial electronic interactions is a promising but still challenging strategy for preventing shuttling polysulfides in lithium–sulfur batteries. Herein, ultrathin nonlayered NiO/Ni 3 S 2 nanosheets are...
Single-atom Pt-based catalysts display a promising strategy to enhance the atomic utilization of noble metals while attaining desirable electrocatalytic properties. Moreover, rationally selecting substrate helps optimize water dissociation energy as well promote H* conversion. Herein, we dispersed monoatomic Pt with ultralow content onto porous nickel nanosheets accelerate reaction kinetics hydrogen evolution in an alkaline medium.

Abstract Noble metal single‐atom‐catalysts (SACs) have demonstrated significant potential to improve atom utilization efficiency and catalytic activity for hydrogen evolution reaction (HER). However, challenges still remain in rationally modulating active sites activities of SACs, which often results sluggish kinetics poor stability, especially neutral/alkaline media. Herein, precise construction Pt single atoms anchored on edge 2D layered Ni(OH) 2 (Pt‐Ni(OH) ‐E) is achieved utilizing situ...

Here, we have developed a more temperature-tolerant emitter with gradient emittance, which can enable adaptation to changing environmental conditions. Such thermal is mainly constructed by multilayered films composed of nitrogen (N)-doped Ge2Sb2Te5 (N-GST) and an underlying metal film. The proposed device not only possesses special wavelength selectivity in the middle infrared range but also dynamically adjust average emissivity (from 0.13 0.83) through degree crystallization. Besides, N...
Abstract Lithium–sulfur (Li–S) batteries are prospective as one of the most promising candidates for next‐generation energy storage systems owing to high density and cost‐effectiveness. Compared with normal bulk sulfur, electrochemistry behaviors sulfur chains inside single‐wall carbon nanotubes (SWCNTs) have rarely been investigated. Herein, type 1D chain encapsulated in SWCNTs (S@SWCNTs) is designed cathode Li–S batteries. Experimental studies functional theory (DFT) calculations reveal...
