Abstract Single-atom catalysts anchoring offers a desirable pathway for efficiency maximization and cost-saving photocatalytic hydrogen evolution. However, the single-atoms loading amount is always within 0.5% in most of reported due to agglomeration at higher concentrations. In this work, highly dispersed large (>1 wt%) copper were achieved on TiO 2 , exhibiting H evolution rate 101.7 mmol g −1 h under simulated solar light irradiation, which than other photocatalysts reported, addition...
Abstract This study addresses the challenge of designing simple and environmentally friendly methods for preparation effective electromagnetic wave (EMW) absorbing materials with tailored microstructures multi‐component regulation. N, O doped walnut‐like porous carbon composite microspheres loaded FeCo nanoparticles (WPCM/Fe–Co) are synthesized through high‐temperature carbonization combined soap‐free emulsion polymerization hydrothermal methods, avoiding use toxic solvents complex...
This paper used 3 types of graphite with different physical structures as the porous matrix to prepare composite phase change materials (PCMs), and investigated their photo-thermal conversion performance application in battery thermal management. Multiple structure minerals, including microcrystalline (MG), scale (SG), expanded (EG) were matrix, while stearic acid (SA) acts material. The vacuum impregnation method was applied SA/MG, SA/SG, SA/EG, SA/MG1, SA/EG1was/were prepared by ethyl...
Printable triple mesoscopic structures for organic–inorganic hybrid perovskite solar cells (PSCs) have recently obtained significant attention, and they possess a superior long-term stability in comparison to those of planar structured PSCs. In with structures, however, typically show lower open-circuit voltages (Voc). Evidence suggests that nonradiative recombination governed by the mismatched energy levels between film electron-transporting layer (or hole-transporting layer) is main cause...
Xylene is a volatile organic compound which harmful to the human health and requires precise detection. The detection of xylene by an oxide semiconductor gas sensor important research direction. In this work, Co3O4 decorated flower-like SnO2 nanorods (SnO2/Co3O4 NRs) were synthesized simple effective two-step method. SnO2/Co3O4 NRs show high response (R g/R = 47.8 for 100 ppm) selectivity at operating temperature 280 °C, exhibit stability in continuous testing. resulting nanocomposites...
Fully printable, hole-conductor-free, carbon-based perovskite solar cells are attractive and promising for industrial production due to their low cost high stability. However, the efficiency of this type device is difficult improve undesirable interfacial contact during printing process compared spin coating higher recombination ratio than devices with a hole conductor. Herein, porous anatase nanocrystal (Nano-TiO2) derived by MIL-125, titanium-based metal–organic frameworks (MOFs), was used...
Abstract Electrocatalytic reduction of CO 2 over zeolitic imidazolate frameworks (ZIFs) generally has poor activity and low Faradaic efficiency due to the contact between conductive substrate ZIFs synthesized by ex‐situ method. Here, ZIF‐8 films on Zn foils (ZIF‐8/Zn) fabricated in‐situ electrochemical deposition were used for electroreduction in ionic liquid‐based ternary electrolyte. Tunable morphology thickness film can regulate electroreduction. The ZIF‐8/Zn‐40 electrode demonstrates...
Surface defects, which mediate nonradiative recombination, are detrimental to both the photovoltaic performance and stability of perovskite solar cells (PSCs). Improving photovoltage fill factor (FF) in screen‐printed mesoporous PSCs is a major challenge for approaching power conversion efficiency (PCE) planar configured devices. Herein, novel bifacial passivation strategy simultaneously suppresses deep trap states within TiO 2 through interaction between functional groups defects...
