Using selenium and zirconium metal, Ce0.8Zr0.2O2 MOF was processed which was thermally activated with cobalt tetraoxide to develop Co/Ce0.8Zr0.2O2 catalyst for methane conversion from carbon dioxide. Higher CO2 transformation to methane (> 80%) with advanced methane selectivity (99%) was achieved...

For which of the following molecules would the intermolecular forces be influenced mainly by hydrogen bonding? CH3COCH3 O2 PH3 NO2 BF3 What is the maximum number of other molecules that can joined together through hydrogen bonding with water?
What is the strongest of the intermolecular forces? What intermolecular forces act between the molecules of O2? How are vapor pressure and intermolecular forces related? a) The stronger the intermolecular forces, the higher the vapor pressure. b) The weaker the intermolecular forces, the lower the...
This commentary focuses on the conceptual interpretation of the bonding of O2 and NO to heme in oxyheme and nitrosylheme complexes, using high-level ab initio complete active space self-consistent field (CASSCF)/molecular mechanical (MM), gas-phase CASSCF, and CASSCF followed by second-order ...
Bonding in the ground state of C2 is still a matter of controversy, as reasonable arguments may be made for a dicarbon bond order of 2, 3, or 4. Here we report on photoelectron spectra of the C2− anion, measured at a range of wavelengths using a high-resolution photoelectron imaging...
It is a lot easier to gain two, so oxygen usually forms an O2− ion. In a similar vein, lithium is group 1, so it only has one electron. It needs to either gain seven electrons or lose just one. Since it is easier to lose one than it is to gain seven, it gives up its ...
