The carbonate-modified Ni/La2O2CO3 catalyst displays a superior catalytic activity, stability, and CO tolerance in CO2 methanation reactions in comparison with Ni/La2O3 catalyst. The structure of Ni-La2O2CO3 interfaces is verified to be stable against thermal decomposition and reduction reaction,...
Moreover, the fraction of each metal species varies sensitively depending on the reaction condition. This can eventually alter their degree of participation as precursors in metal NC synthesis. Thus, to elucidate the formation mechanism of metal NCs and control their ensemble uniformity, it is ...
Diverse cyclic and acyclic carbonates such as ethylene carbonate, propylene carbonate, glycerol carbonate, and dimethyl carbonate were synthesized in moderate to good yields by the direct coupling of the corresponding alcohols with carbon dioxide in the absence of metal catalysts and inorganic bases. The...
In this work, the effect of the metal nature on the reaction mechanism of the partial oxidation of ethanol on Pt/CeO2 and Rh/CeO2 catalysts was studied by using diffuse reflectance infrared spectroscopy (DRIFTS) analyses. The results showed that the nature of the metal affected the reaction ...
Coupling deactivated manganese with nickel migration provides sluggish reaction kinetics and induces serious structural instability in the material. Our findings provide new insights and further understanding of electrochemical degradation, which serve to facilitate cathode material design improvements....
Trace metals are immobilised within these cements both by incorporation into the Mg-carbonate mineral, hydromagnesite, likely by substitution for Mg, and by physical trapping of metal-rich grains that are liberated during mineral processing and weathering. This indicates that if mineral carbonation of...
Jin et al. [201] prepared CoP and Ni2P heterojunction with layered structure as electrodes, and found that the products had excellent durability and catalytic effect on battery reaction after testing. On the other hand, the synergistic effect of layered structure and heterojunction leads to the ...
and properties of the resulting MOFs. Hydrothermal synthesis is similar to solvothermal synthesis, but the reaction takes place in an aqueous solution instead of an organic solvent. This method is advantageous for the synthesis of water-stable MOFs. Microwave synthesis involves the use of microwave ...
The cooperative catalysis between lipase-active site and single Pd atom accelerates alkyl-alkyl cross-coupling reaction between 1-bromohexane and B-n-hexyl-9-BBN with high efficiency (TOF is 540 h−1), exceeding that of the traditional catalyst Pd(OAc)2 by a factor of 300 under ambient...
