Intermolecular interactions in adsorbate-carbon systems of various nano- and adsorption textures

Effect of surface acid groups associated with amorphous and structured carbon on the catalytic hydrodechlorination of chlorobenzenes

“…Bachiller‐Baeza et al ,27 on the other hand, examined the gas phase hydrogenation of crotonaldehyde over Pt supported on non‐oxidized and H 2 O 2 ‐oxidized graphite and found that oxygen groups can influence product selectivity when the catalyst was synthesized from a H 2 PtCl 6 precursor but there was no apparent catalytic response for preparations employing Pt(NH 3 ) 4 (OH) 2 as precursor. In terms of CB and DCB activation, there is evidence in the literature that haloarenes can adsorb both on the metal phase4, 42 and on the carbon support in liquid70–72 and gas phase54–57, 73 applications. The difference in catalytic performance must, therefore, be due to reactant interaction with the carbon surface, which appears to be influenced by the presence of acid groups.…”

Adsorption isotherms and kinetics of methylene blue on a low-cost adsorbent recovered from a spent catalyst of vinyl acetate synthesis

“…Both the precursor material and the experimental conditions in the preparation process play a decisive role in AC modeling [28,29]. Because of the wide variety of adsorbates, there are many possible adsorption processes [30] making the production of one universal AC sound utopian. Parameters such as a relatively high surface area and well developed porosity are considered the most influential physical properties that may affect the adsorption capacity of an AC, since it is these features that provide ample adsorption sites for molecules to attach to [31].…”
