Sentence examples for aqueous catalyst from inspiring English sources

Obtained insights were used to establish a rate expression for this reaction, incorporating the interfacial area between organic substrate and aqueous catalyst phase.

The photocatalytic oxidation and mineralization of petroleum refinery wastewater in aqueous catalyst suspensions of titanium dioxide (TiO2), Degussa P25 (80% anatase, 20% rutile), were carried out in a batch circulating photocatalytic reactor.

The location of the biphasic reaction is contested: is it the bulk of the aqueous catalyst solution or the interfacial layer aqueous/organic liquid?

Our results clearly showed that a faster oxidation rate was obtained using the silica supported with surfactant molecules than with the corresponding supported aqueous catalyst on unmodified silica.

Open image in new window Fig. 7 The images of the sulfur containing aqueous catalyst media and after settling down; a the as-received sulfur-catalyst liquid solution, b after 1 h setting down.

UV vis spectra of RhB in contact with different catalyst samples after 30-min dark adsorption/desorption are shown in Fig. 6a, b. Figure 6c shows that the degradation efficiency of the RhB (20 mg/L) in aqueous catalyst dispersion with ZnO-SnO2 hollow spheres could reached 99.85% within 40 min while the ZnO hollow spheres need more time.

To develop the way to separate the sulfur from the aqueous phase catalyst system, we have taken 1000 ml of the sulfur rich catalyst solution and left it in the beaker statically in air (as shown in Fig. 7).

The photodegradation efficacy of the prepared material was evaluated by varying parameters like aqueous pH, catalyst dosage and dye concentration for photodegradation of the dye molecules.

A rate equation has been proposed, considering that each particle of supported aqueous phase catalyst is a microreactor, where the reaction takes place at the aqueous/organic interface.

The hydrogenation of trans-cinnamaldehyde catalysed by a supported aqueous phase catalyst of RhCl TPPTS 3 [TPPTS: trisodium salt of tris m-sulfophenyl phosphine] on silica was investris m-sulfophenyl phosphineuct selectivity, reaction kinetics and mass transfer characteristics.

This suggests that the sulfur could be easily filtered from the aqueous phase catalyst system.
