Developing a facile route to access active and well-defined single atom sites catalysts has been major area of focus for atoms (SACs). Herein, we demonstrate simple approach generate atomically dispersed platinum via thermal emitting method using bulk Pt metal as precursor, significantly simplifying synthesis routes minimizing costs. The ammonia produced by pyrolysis Dicyandiamide can coordinate with strong coordination effect. Then, the volatile Pt(NH3) x be anchored onto surface defective...
It is highly desired but remains a great challenge to develop nonprecious metal single-atom catalysts supersede the Pt-based material for oxygen reduction reaction (ORR). Herein, we report porous nitrogen-doped carbon matrix catalyst with 3.5 wt % single Fe atoms (Fe SAs/N–C) through versatile molecules-confined pyrolysis strategy. In 0.1 M KOH condition, SAs/N–C possesses half-wave potential of 0.91 V vs RHE. more challenging acidic solution, also offers good ORR activity, comparable...
Herein, we report a heterogeneous single iron atom catalyst exhibiting excellent peroxidase, oxidase and catalase enzyme-like activities (defined as enzymes, SAEs), exceeding those of Fe<sub>3</sub>O<sub>4</sub> nanozymes by factor 40.
Abstract Nanomaterials with enzyme‐mimicking characteristics have engaged great awareness in various fields owing to their comparative low cost, high stability, and large‐scale preparation. However, the wide application of nanozymes is seriously restricted by relatively catalytic activity poor specificity, primarily because inhomogeneous sites unclear mechanisms. Herein, a support‐sacrificed strategy demonstrated prepare single iron site nanozyme (Fe SSN) dispersed on porous N‐doped carbon....
Abstract An ordered mesh of palladium with a thickness about 3 nm was synthesized by solution‐based oxidative etching. The ultrathin nanomeshes have an interconnected two‐dimensional network densely arrayed, quasi‐nanoribbons that form open holes. unique mesoporous structure and high specific surface area make these Pd display superior catalytic performance for ethanol electrooxidation (mass activity 5.40 Am g −1 7.09 mA cm −2 at 0.8 V vs. RHE). Furthermore, the regular can be applied to...
The sintering of supported metal nanoparticles is a major route to the deactivation industrial heterogeneous catalysts, which largely increase cost and decrease productivity. Here, we discover that palladium/gold/platinum distributed at interface oxide supports nitrogen-doped carbon shells would undergo an unexpected atomization process against high temperatures, during can be transformed into more active atomic species. in situ transmission electron microscopy images reveal abundant...
By using WCl6 as a precursor and absolute ethanol solvent, ultrafine W18O49 nanowires (UFNWs) were synthesized by one-pot solution-phase method used gas sensing materials. Their crystal structure, morphology, specific surface area can be regulated controlling precisely the content of in solution. It has been found that, when is 4 mg/mL, formed products are UFNWs with diameter about 0.8 nm, only one plane [010] exposed, 194.72 m2/g. After test, we that they have excellent selectivity to...
Nanomaterials with natural enzyme-mimicking characteristics have aroused extensive attention in various fields owing to their economical price, ease of large-scale production, and environmental resistance. Previous investigations demonstrated that composition, size, shape, surface modification play important roles the enzymelike activity nanomaterials; however, a fundamental understanding crystal facet effect, which determines energy or reactivity, has rarely been reported. Herein, fluorite...
Co single atoms anchored on ultrathin two-dimensional nitrogen-doped carbon (Co SAs/2D N-C) were in situ derived from 2D metal-organic frameworks (MOFs). These nanosheets functionalized by the isolated possess a high density of active sites and accessible surfaces, exhibiting an exceptional catalytic performance oxidation silanes.
In this work, a facile synthesis method was adopted to synthesize MOF-14 with mesoporous structure. The physical properties of the samples were characterized by PXRD, FESEM, TEM and FT-IR spectrometry. By coating mesoporous-structure on surface quartz crystal microbalance (QCM), fabricated gravimetric sensor exhibits high sensitivity p-toluene vapor even at trace levels. Additionally, limit detection (LOD) obtained experimentally is lower than 100 ppb, theoretical 57 ppb. Furthermore, good...
SnO2-based semiconductor gas-sensing materials are regarded as some of the most crucial sensing materials, owing to their extremely high electron mobility, sensitivity, and excellent stability. To bridge gap between laboratory-scale SnO2 its industrial applications, low-cost high-efficiency requirements must be met. This implies need for simple synthesis techniques, reduced energy consumption, satisfactory performances. In this study, we utilized a surfactant-free method modify nanoparticles...
