This paper presents the results of quantum chemical simulation and experiments to determine the effects of the adsorption of hydrogen onto gold–nickel nanoparticles. Numerical experiments revealed that the most energetically favorable positions of adsorbed hydrogen atoms are mainly located in the vicinity of gold atoms due to electron density redistribution between gold and nickel in bimetallic clusters...
We studied adsorption state of water molecules in a porous coordination polymer (PCP) using infrared spectroscopy. We observed two absorbance peaks below 4% relative humidity (RH) that originate from OH stretch modes of adsorbed water molecules. Their peak frequencies and areas indicate that one of the OH is free, and the other is hydrogen bonded. We also found that Free-OH plays a role of water attraction...
For comprehensive utilization of CO contained in closed carbide furnace tail gas, the purification of HCN in the artificial tail gas mixed with pure gases was studied by means of adsorption using modified activated carbon. In range of this study the optimum conditions for preparing modified activated carbon are: NaOH concentration is 10 wt% and sulfonated cobalt phthalocyanine (CoPcS) concentration...
