Co/Ni/Mo-based oxides are promising candidates for hydrogen evolution reaction (HER). However, these electrocatalysts often exhibit unsatisfactory HER performance due to the lack of active sites. Herein, an in situ electrochemical activation strategy is proposed to modify the surface structure of a Co-Ni-Mo-O catalyst. During the HER in alkaline electrolyte, the Co-Ni-Mo-O nanosheets display an activation

Photovoltaic-electrochemical (PV-EC) fuel production is a promising technology that combines solar energy conversion and electrochemical catalysis to produce sustainable hydrogen and hydrocarbon from renewable sources.

Mixing cations with different chemical properties to induce the generation of asymmetric structures is a new approach for tuning the optical properties of hybrid organic-inorganic metal halide (HOIMH). In this study, zero-dimensional (C9N3H15)(C9H13SO)MBr6 (M = Bi/Sb, [C9N3H15]2+ = [(C4N2H10)(C5NH5)]2+ and [C9H14SO]+ = [CH3(C6H4)OS(CH3)2]+) are synthesized. Two different cations cause both compounds

A series of four-coordinated PtII(C^N)(N-donor ligand)Cl-type complexes have been synthesized through combination between long-size C^N-type and N-donor ligands. In addition, by variating the coordinating site in the N-donor ligand, distorted molecular configuration has been constructed in these complexes.

Binary transition metal sulfides are considered to be a promising material for supercapacitors, possessing a richer electrochemical active site and superior electrochemical performance. Metal-organic frameworks (MOFs) are often used as self-sacrificing templates for the preparation of metal sulfides. Usually, direct sulfidation of MOFs tends to cause collapse of the morphological structure and blockage

Ternary transition metal oxides (TMOs) are deemed as the hopeful anode materials of Li-ion batteries (LIBs) because of the large theoretical capacity, and rich redox reaction. Nevertheless, inherent semiconductor characteristic, and enormous volume variation of TMOs during cycling bring about sluggish reaction kinetics, fast capacity fading and poor rate capability. Herein, a three-dimension (3D) porous

The synthesis of [2Fe-2E] (E = S and Se) complexes supported by an N-alkyl,N'-aryl-β-diketiminate ligand is described. The [2Fe-2S] model compound has an unusually long Fe···Fe distance, but the equivalent distance in the [2Fe-2Se] compound is comparable to those reported in the literature. These model compounds display varying electron transfer capabilities, which were elucidated through electronic

Lithium metal batteries have been regarded as typical representative of high-energy storage systems. However, the lithium dendrite growth and fragile solid electrolyte interface (SEI) leads to safety issues and unsatisfactory performances.
