In this work, we prepared flexible carbon-fiber/semimetal Bi nanosheet arrays from solvothermal-synthesized carbon-fiber/Bi2O2CO3 via a reductive calcination process. The can function as photocatalysts and photoelectrocatalysts for 2,4-dinitorphenol oxidation. Compared with arrays, the newly designed show enhanced ultraviolet-visible (UV-vis) light absorption efficiency photocurrent, photocatalytic, photoelectrocatalytic activities. Photocatalytic analyses indicate that surface plasmon...

Highly crystalline films of a silver-based coordination polymer, [Ag5(C6S6)]n (Ag-BHT, BHT = benzenehexathiol), have been prepared. The structure Ag-BHT, solved by combining rotation electron diffraction and powder X-ray techniques, indicates that it has lamellar with alternatively stacked two-dimensional Ag–S networks layers composed one-dimensional metal-dithiolene polymers. In addition, the polycrystalline Ag-BHT film shows high electrical conductivity up to 250 S·cm–1 at 300 K....
Nanostructuring and metal–support interactions have been explored as effective methods to improve the electrocatalytic activity in heterogeneous catalysis. In this study, we fabricated ultrasmall Ru nanoparticles (NPs) dispersed on S-doped graphene (denoted Ru/S-rGO) by a facile "one-pot" procedure. The experimental results indicated that both S doping moderate degree of oxidization GO can induce formation high dispersion NPs with larger electrochemically active surface areas for exposing...
Platinum-based (Pt-based) catalysts are considered as the most effective electrocatalysts for hydrogen evolution reaction (HER). Because of high cost, it is essential to improve mass activity and durability platinum by studying relationship between Pt supports. Herein, a series modified Ti3C2Tx-based (T = O, OH, F; MXene) supports synthesized, was loaded wet-impregnation photoinduced reduction method. This first report that Pt-based MXenes have been used promote HER efficiency with promising...
Abstract Metal-free organic perovskite ferroelectric materials have been shown recently to a number of attractive properties, including high spontaneous polarization and piezoelectric coefficients. In particular, slow evaporation solutions containing amines, inorganic ammoniums, dilute hydrohalogen acid has produce several in the MDABCO-NH 4 -I 3 family (MDABCO is N-methyl-N’-diazabicyclo[2,2,2] octonium). present work, we study by first-principles calculations origin polarizaiton,...
Abstract The development of facile methods for constructing highly active, cost‐effective catalysts that meet ampere‐level current density and durability requirements an oxygen evolution reaction is crucial. Herein, a general topochemical transformation strategy posited: M‐Co 9 S 8 single‐atom (SACs) are directly converted into M‐CoOOH‐TT (M = W, Mo, Mn, V) pair‐sites under the role incorporating atomically dispersed high‐valence metals modulators through potential cycling. Furthermore, in...
NASICON-type (Na3Zr2Si2PO12) electrolytes are regarded as one of the most promising solid-state sodium-ion due to their exceptional air stability and extensive electrochemical window. Nevertheless, ionic conductivity still requires further enhancement in comparison that a conventional liquid electrolyte. This study presents strategy enhance performance NASICON via ScF3 substitution. Through optimization substitution concentration, rhombohedral phase maintains at room temperature was...
The effects of nanoconfined water and the charge storage mechanism are crucial to achieving ultrahigh electrochemical performance two-dimensional transition metal carbides (MXenes). We propose a facile method manipulate through surface chemistry modification. By introducing oxygen nitrogen groups, more active sites were created for Ti3C2 MXene, interlayer spacing was significantly increased by accommodating three-layer water. Exceptionally high capacitance 550 F g-1 (2000 cm-3) obtained with...
