Herein, we demonstrate that the synergetic interaction between neighbouring Pt monomers on MoS2 greatly enhanced the CO2 hydrogenation catalytic activity and reduced the activation energy relative to isolated monomers. Neighbouring Pt monomers were achieved by increasing the Pt mass loading up to 7.5% ...
The atomic-resolution high-angle-annular-dark-field scanning transmission electron microscopy (HAADF-STEM) image of Co-bCN was collected to disclose the specific distribution status of Co species. The isolated dots marked by orange circles are attributed to Co single atoms, undoubtedly proving the at...
Contrarily, it involves specific threats such as nuclear proliferation, radiation, and management of radioactive waste, which can thwart the relative acceptance of this potential energy option. Therefore, debate and further research are required to reach a national-level political consensus about the ...
Nevertheless, it is worth noting that, while the utilization of CO2 has potential to reduce greenhouse gas emissions into the atmosphere, CO2 has disadvantages as a chemical reactant due to its relative significant chemical inertness. This inertness is the underlying reason why CO2 has b...
Ternary diagram of relative abundances of Ar-N2-He of the studied samples, showing also the composition of air saturated water (ASW, grey triangle) and air (open triangle). b. Ternary diagram of relative abundances of He-Ar-CO2, showing the composition of ASW, air, deep gas and the ...
During further heating from 300 to 350 °C in vacuum, no changes are observed in the relative amounts of Mg and Co phases. When the temperature increases to 400 °C, the MgCo compound is formed by depleting the Co content (~15.0 wt%) and by involving all available Mg (~6 wt%) into...
These relative weights computed from the chemical equation are sometimes called equation weights.Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance....
The results obtained in this study reveal that the ECR efficiency as well as the selectivity for CO generation on Au electrode surfaces can be dominated by the surface atomic arrangements and that relative Faradaic selectivity evaluation by OLEMS is helpful for discussion of the ECR process....
At a low-pressure, the relative adsorption capacities were higher than in the high-pressure range, which can be attributed to the fact that the highest adsorption energy is found in the smallest pores at low pressure at first and then advances toward the larger pores with increased pressure, ...
However, the relative amount of Pd3Zr increases slightly with respect to Pd2Zr. This is also understandable on the basis of the Pd-Zr phase diagram: Pd3Zr is the thermodynamically most stable compound in the Pd-Zr system [25], with the system most likely approaching structural equilibrium. ...
