Graphene that had nanomeshes, only one to two graphene layers, and specific surface areas of up 1654 m(2) g(-1) was produced on gram-scale by template growth porous MgO layers. Its unique structure gave excellent electrochemical capacitance (up 255 F g(-1)), cycle stability rate performance.
Few-layered graphene networks composed of phosphorus and nitrogen dual-doped porous (PNG) are synthesized via a MgO-templated chemical vapor deposition (CVD) using (NH4)3PO4 as N P source. atoms have been substitutionally doped in since the doping takes place at same time with growth CVD process. Raman spectra show that amount defects or disorders increases after incorporated into frameworks. The levels measured by X-ray photoelectron spectroscopy 0.6 2.6 %, respectively. As anodes for Li...
The shape-controlled synthesis of multicomponent metal nanocrystals (NCs) bounded by high-index facets (HIFs) is significant importance in the design and high-activity catalysts. We report herein preparation Pt-Ni alloy NCs tuning their shape from concave-nanocubic (CNC) to nanocubic hexoctahedral (HOH). Owing synergy HIFs electronic effect alloy, as-prepared CNC HOH exhibited excellent catalytic properties for electrooxidation methanol formic acid, as well oxygen reduction reaction (ORR).
Biochar, a by-product from the fast pyrolysis of pine wood, was used as support material for synthesis carbon-encapsulated iron nanoparticles. The nanoparticles were characterized physicochemical properties by multiple morphological and structural methods (e.g., SEM, TEM, XRD, FTIR, TPD). Fischer–Tropsch (FTS) process carried out to evaluate catalytic activity on conversion biomass-derived gas (bio-syngas) liquid hydrocarbons. Characterization results revealed that had core–shell structures...
A series of catalysts three-dimensionally ordered macroporous (3DOM) Ce0.8Zr0.2O2-supported gold nanoparticles with controllable sizes were successfully synthesized by the facile method gas bubbling-assisted membrane reduction (GBMR). All possess well-defined 3DOM structures, which consist interconnected networks spherical voids, and Au are well dispersed supported on inner wall uniform macropore. The relationship between particle ability to adsorb activate oxygen was characterized means...
Pt–Pd bimetallic alloy nanostructures with highly selective morphologies such as cube, bar, flower, concave and dendrite have been achieved through a facile one-pot solvothermal synthesis. The effects of shape-controllers (sodium dodecyl sulfate (SDS), ethylenediamine-tetraacetic acid disodium salt (EDTA-2Na), NaI) solvents (water/DMF) on the were systematically investigated. electrocatalytic activities these toward formic oxidation tested. results indicated that nanocrystals exhibited...

Removal functional groups or highly active C atoms during has led formation much thinner solid-electrolyte interface...
Abstract The shape‐controlled synthesis of multicomponent metal nanocrystals (NCs) bounded by high‐index facets (HIFs) is significant importance in the design and high‐activity catalysts. We report herein preparation Pt–Ni alloy NCs tuning their shape from concave‐nanocubic (CNC) to nanocubic hexoctahedral (HOH). Owing synergy HIFs electronic effect alloy, as‐prepared CNC HOH exhibited excellent catalytic properties for electrooxidation methanol formic acid, as well oxygen reduction reaction (ORR).
Abstract An experimental and computational study is presented on the hydrodynamic characteristics of FCC particles in a turbulent fluidized bed. Based Eulerian/Eulerian model, fluid dynamics (CFD) model incorporating modified gas‐solid drag has been presented, parameters are examined by using commercial CFD software package (FLUENT 6.2.16). Relative to other models, one gives reasonable prediction comparison with data. The hydrodynamics show more sensitive coefficient restitution than flow...
Engineering metal–organic frameworks (MOF) for heterogeneous catalysts have been of extreme interest since they could bridge the gap between homogeneous and catalysis. We designed synthesized gold functionalized IRMOF-3 by post-covalent modification (PM) one-pot (OP) synthesis methods.
