Developing efficient piezocatalytic systems for two-electron water splitting (TEWS) with producing H2 and O2 shows great promise to meet the industrial demand. Herein, Ag single atoms (SAs) clusters are co-anchored on carbon nitride (AgSA+C -CN) serve as multifunctional sites TEWS. The SAs enhance in-plane piezoelectric polarization of CN that is intimately modulated by atomic coordination induced charge redistribution, afford strong interfacial electric field remarkably promote out-of-plane...
Inferior contact interface and low charge transfer efficiency seriously restrict the performance of heterojunctions. Herein, chemically bonded α-Fe2 O3 /Bi4 MO8 Cl (M=Nb, Ta) dot-on-plate Z-scheme junctions with strong internal electric field are crafted by an in situ growth route. Experimental theoretical results demonstrate that provides a powerful driving force for vectorial migration photocharges between Bi4 , interfacial Fe-O bond not only serves as atomic-level flow highway but also...
Abstract Single-atom catalysts show excellent catalytic performance because of their coordination environments and electronic configurations. However, controllable regulation single-atom permutations still faces challenges. Herein, we demonstrate that a polarization electric field regulates single atom forms periodic one-dimensional Au arrays on ferroelectric Bi 4 Ti 3 O 12 nanosheets. The greatly lower the Gibbs free energy for CO 2 conversion via Au-O=C=O-Au dual-site adsorption compared...
Abstract Single‐atom catalysts (SACs) are demonstrated to show exceptional reactivity and selectivity in catalytic reactions by effectively utilizing metal species, making them a favorable choice among the different active materials for energy conversion. However, SACs still early stages of conversion, problems like agglomeration low conversion efficiency hampering their practical applications. Substantial research focus on support modifications, which vital SAC stability due intimate...
For heterojunction system, the lack of stable interfacial driving force and definite charge transfer channel makes separation efficiency unsatisfactory. The photoreaction mechanism occurring at interface also receives less attention. Herein, a 2D/2D Z-scheme junction BiOBr@NiFe-LDH with large-area contact featured by short hydrogen bonds strong electric field (IEF) is synthesized, in situ photoinduced metallic species assisting demonstrated. between O atoms from BiOBr H NiFe-LDH induce...
Point-to-face Z -scheme Cd 0.6 Zn 0.4 S/g-C 3 N 4 with a robust internal electric field was synthesized by an in situ growth strategy and showed highly efficient H 2 O production activity.
Developing high-performance visible-light driven photocatalyst (λ≥420 nm) makes significance for the efficient utilization of solar energy. Mass production and easy recycling are equally important practical application powdery photocatalyst. However, it is challenging to meet above requirements at same time. In this work, we develop an responsive layered oxyiodide CdBiO2I nanosheets prepared by a facile direct precipitation method ambient atmosphere, demonstrate its upgradable features well...
Single-crystal dendritic ZnO nanostructures in appearance of macroscale mass production have been synthesized via the vapor-phase transport method with Cu catalyst at 930°C. The hierarchical dendrites a long central trunk and lots multilevel branches are composed well-oriented nanorods whose diameters range from 60to800nm. Gas sensors based on as-synthesized products exhibit high sensitivity selectivity to H2S gas room temperature through detecting various gases. large modulation energy...
Abstract Rapid bulk charge recombination and mediocre surface catalytic sites harshly restrict the photocatalytic activities. Herein, aforementioned concerns are well addressed by coupling macroscopic spontaneous polarization atomic‐site engineering of CdS single‐crystal nanorods for superb H 2 photo‐production. The oriented growth along polar axis, vectorially superimposing substantial units with orderly arrangement, renders a strong electric field (20.1 times enhancement), which boosts...
Hydrogen sulfide (H2S), as a typical atmospheric pollutant, is neurotoxic and flammable even at very low concentration. In this study, we design stable H2S sensors based on ZnO-carbon nanofibers. Nanofibers with 30.34 wt% carbon are prepared by facial electrospinning route followed an annealing treatment. The resulting show excellent selectivity response compared to the pure ZnO nanofiber sensors, particularly in range of 102–50 ppm H2S. Besides, they exhibited nearly constant approximately...
