Unique catalysis of Ni-Al hydrotalcite derived catalyst in CO2 methanation:cooperative effect betwee
Ni-Al hydrotalcite derived catalyst (Ni-Al2O3-HT) exhibited a narrow Ni particle-size distribution with an average particle size of 4.0 nm. Methanation of CO2 over this catalyst initiated at 225?C and reached 82.5%CO2 conversion with 99.5%CH4 selectivity
Hydrothermal synthesis of spindle-like Li2FeSiO4-C composite as cathode materials for lithium-ion ba
In this paper, we report on the preparation of Li2FeSiO4, sintered Li2FeSiO4, and Li2FeSiO4-C composite with spindle-like morphologies and their application as cathode materials of lithium-ion batteries. Spindle-like Li2FeSiO4 was synthesized by a facile
Although most transition metals have been tested as the promoter to Pt for electrocatalysis toward fuel cell reactions, semi-conductor elements, such as Si, have hitherto not been examined. Here we report a simple synthesis of intermetallic Pt2Si electrod
Lithium metal batteries (LMBs) of an ultrahigh theoretical energy density have attracted lots of attentions for a wide range of practical applications.However,there are still numerous challenges in LMBs system,such as poor cycling performance,complicated
Excellent complete conversion activity for methane and CO of Pd/TiO2-Zr0.5Al0.5O1.75 catalyst used i
Palladium catalysts are supported on TiO2, ZrO2, Al2O3, Zr0.5Al0.5O1.75 and TiO2-Zr0.5Al0.5O1.75 prepared by co-precipitation method, re-spectively. Catalytic activities for methane and CO oxidation are evaluated in a gas mixture that simulated the exhaus
Direct conversion of fructose-based carbohydrates to 5-ethoxymethylfurfural catalyzed by AlCl3·6H2O/
The coke deposition on HZSM-5/SAPO-34 composite catalysts has been studied in the conversion of ethanol to propylene.The HZSM-5/SAPO-34 composite catalysts were synthesized by hydrothermal method (ZS-HS) and fully blending (ZS-MM).The used catalysts were
Creating mesopores in ZSM-48 zeolite by alkali treatment: Enhanced catalyst for hydroisomerization o
ZSM-48 zeolites with various Si/Al ratios were hydrothermally synthesized in the H2N(CH2)6NH2 (HDA)-containing media.The obtained samples were highly crystallized with minor mixed phases as evidenced by X-ray powder diffraction (XRD).The alkaline treated
