Electrochemical reduction of CO2 to multi-carbon fuels and chemical feedstocks is an appealing approach mitigate excessive emissions. However, the reported catalysts always show either a low Faradaic efficiency C2+ product or poor long-term stability. Herein, we report facile scalable anodic corrosion method synthesize oxygen-rich ultrathin CuO nanoplate arrays, which form Cu/Cu2O heterogeneous interfaces through self-evolution during electrocatalysis. The catalyst exhibits high C2H4 84.5%,...
A highly efficient hybrid photocatalytic system consisting of Ni(HCO3)2 and mesoporous TiO2 microrods was successfully fabricated by a hydrothermal approach. The involvement cocatalyst resulted in significant improvement the hydrogen evolution on host photocatalyst under artificial sunlight irradiation. optimized photocatalysis with 2.5% (mole ratio) loading displayed highest rate 1798.0 μmol g–1 h–1, which more than 18 times higher that pure TiO2. On basis photoluminescence spectroscopy...
Abstract Lack of effective strategies to regulate the internal activity MoS 2 limits its practical application for hydrogen evolution reactions (HERs). Doping heteroatoms without forming aggregation or an edge enrichment is still challenging, and effect on HER needs be further explored. Herein, a two‐step method developed obtain multi‐metal‐doped H‐MoS , which includes intercalation layered MoO 3 precursor with following sulfurization. Benefiting from capability uniformly simultaneously...
With multiphoton excited upconversion nanoparticles (UCNPs) as energy transducer, ultraviolet (UV) light responsive titanium dioxide (TiO2) can be triggered indirectly by near-infrared (NIR) for deep-tissue photodynamic therapy (PDT) through the fluorescence resonance transfer (FRET) strategy. Compared to pristine TiO2, absorption of hydrogenated black TiO2 (H-TiO2) in visible (vis) and NIR regions presents a marked improvement performance, which leads H-TiO2 enhance its overall activity....
Abstract Ultrathin nickel (Ni)‐based sulfide nanosheets have been reported as excellent electrocatalysts for overall water splitting; however, the uncontrollability over thickness due to nonlayered structure still hampers its practical application. Herein, a simple topochemical conversion strategy is employed synthesize cobalt‐doped Ni 3 S 2 (Co‐Ni ) ultrathin on foam. The Co‐Ni are controlled synthesized by using Co‐Ni(OH) templates with anneal and sulfurization treatment, showing...
Designing cost-effective and highly active oxygen reduction reaction (ORR) catalysts is critical for the development of Zn-air batteries (ZABs). Iron-nitrogen-carbon (Fe-N-C) with single-atom Fe-Nx sites are considered as one most promising alternatives to noble Pt but hindered by unsatisfactory activity durability. Herein, a NaCl template-assisted in situ pyrolysis technique utilized massively fabricate Fe-N-C (SACs) anchored on three-dimensional open-pore carbon networks (denoted 3D SAFe)....
Single-atom catalysts provide efficiently utilized active sites to improve catalytic activities while improving the stability and enhancing level of their bulk metallic counterparts are grand challenges. Herein, we demonstrate a family single-atom with different interaction types by confining metal single atoms into van der Waals gap two-dimensional SnS2. The relatively weak bonding between noble host endows more intrinsic activity compared ones strong chemical bonding, protection offered...
We report the spontaneous formation of uniformly distributed arrays “tips” (tall conical hillocks) upon oxidation palladium (Pd) thin films. The oxide tips depended on thickness and granularity Pd film annealing conditions. As increased from 40 to 200 nanometers, average height 0.5 1.2 micrometers, their distribution became broader, density decreased 55 × 10 6 12 per square centimeter. Enhanced photoelectron emission locations corresponding suggests possible use in field applications.

We present scanning tunneling microscopy (STM) studies of the etching behavior surfaces Si(111)-(7×7) and Si(100)-(2×1) by atomic hydrogen. Etching proceeds via formation volatile SiH4 through a two-step mechanism in which H atoms react with SiH2 SiH3 species on surface at room temperature. By measuring area etch pits STM images taken under same flux conditions, Si(100) is determined to be nearly three times faster than that Si(111) because intermediate hydride products are more readily...
