Sentence examples for binary catalysts and the from inspiring English sources
The stability of Ba Al–O is higher than Ba La O binary catalysts and the conversion of rapeseed oil over Ba Al–O can achieve ~100% at optimum conditions.
The phase transitions of metallic components of binary catalyst and their role in the CNT growth process were discussed.
The optimal experimental conditions were found to be 54.1 °C, agitation speed at 250 rpm with 6 wt.% of CaO/SnO2 (7:3 mass ratio of the binary catalyst) and 10 1 (methanol:oil) molar ratio.
For the binary catalysts, the addition of Co and Ni enhanced the overall activity while W and Mo improved the catalyst selectivity to iC4H8.
A comparison of the activities of the ternary catalysts with the corresponding binary catalysts suggests that the surface vanadium oxide and the additive surface metal oxide redox sites act independently without synergistic interactions.
In the binary catalysts, variation of the ratios of Co to Fe and the total metal loading during the synthesis leads to a markedly different activity and four-electron selectivity for oxygen reduction.
The interpretation of the role played by the relay molecules in the electrocatalytic photodecomposition of water allows a discussion of the preparation and the behaviour of Pt Au binary catalysts used for the production of photolytic hydrogen.
A quinine-derived aminophosphine precatalyst and silver oxide were found to be an effective binary catalyst system and promoted the reaction to afford chiral oxazolines possessing a fully substituted stereocenter with good diastereoselectivities and excellent enantioselectivities.
The PtRu/C electro-catalyst showed the best electro-catalytic activity and the highest tolerance to the poisonous species in the low over-potential range (<0.55 V, 50 °C) among the binary electro-catalysts and the Pt/C, but at the higher potential (>ca. 0.55 V, 50 °C), the Pt/C behaved better than PtRu/C.
Various partial oxidation products were identified on the surface of TiO2 and an 8%SiO2 TiO22 binary catalyst used for the photocatalytic oxidation of gas-phase toluene.
The modification of binary catalysts with gold led to increase the activity in the case of systems containing Co and Cu, and led to maintain the activity in the case of Ni-containing catalysts.
