Sentence examples for basic active sites from inspiring English sources

Catalytic performance of the catalysts was also tested in the gas phase dehydration of glycerol with the intention of investigating relationship between catalytic activity and nature of acidic and basic active sites.

Moreover, when a 1 M KOH solution was used in the process, the creation of new basic active sites resulted in an increase of the photocatalytic activity, even higher than for the fresh material.

The synthesis procedure of activated carbons with basic properties is optimized in order to prepare a basic solid with a high number of strong basic active sites on the surface of the carbon material.

Overall, from the mechanistic interpretation of H2O2 decomposition, it is concluded that the presence of sulphur containing functional groups at the surface of the activated carbons improves the removal of H2O2 in aqueous solutions, but, on the other hand, the selective decomposition of H2O2 via HO formation is enhanced by the presence of basic active sites on the carbon surface.

From Table 2, although both CaO and Calcium-based catalyst render strong basic strength, the binary metal oxide provide higher amount of strong basic active sites as compared to CaO catalyst.

Magnesium aluminum spinel (MgAl2O4), with attractive combination of the properties of good hydrothermal stability, high resistance against sintering, small coefficient of thermal expansion, and great mechanical strength and hardness as well as processing both acid and basic active sites, is widely applied as catalysts or catalyst supports [1].

In the phosphoribosyl-AMP cyclohydrolases a sequence alignment and super-position of the conservation onto the available structures indicates two basic active site elements (see Additional file 1).

The basis for this alkaline pH dependence is unknown, but it could be caused by a highly basic active site, which has to bind six phosphates from the two substrates, or by a missing protein partner, which could alter this toward more acidic pH.

It has been found that the surface basic groups are active sites.

This idea is related to a proposal of Hanson and Rose that natural selection favors the use of the minimal number of acidic and basic residues in active sites, so that such residues tend to be reused when mechanistically reasonable (Hanson and Rose, 1975).

But for Ce0.75Nd0.25O2-δ, with too many basic sites, more of active sites would be occupied and plenty of cerium sulfide species (Ce2S3) would be accumulated on the catalyst during the reaction processes.
