The phrase "amount of active metals" is correct and usable in written English.
It can be used in scientific or technical contexts when discussing the quantity or concentration of active metals in a sample or reaction.
Example: "The experiment measured the amount of active metals present in the solution to determine its reactivity."
Alternatives: "quantity of active metals" or "level of active metals".
The DBT HDS assessment results also revealed that the catalyst containing 17.7 wt% WO3 and 2.4 wt% NiO prepared by the hydrothermal deposition method had the similar DBT HDS activity as a commercial NiW/γ-Al2O3 catalyst containing 23 wt% WO3 and 2.6 wt% NiO, resulting in the greatly decreased amount of active metals for achieving the same HDS activity.
The effect of the preparation method, the support, the precursors, the relative amount of active metals and their role in the formation of intermediates and products are tentatively discussed.
Therefore, our results indicated that the toxicity of NPs was dependent on the amount of active metal reaching the anammox cells.
Amongst these limitations are 1) the lengthy and complicated hydrothermal synthesis procedure, 2) the low amount of active metal incorporated per kilogram of final catalyst, resulting in low space time yields, and 3) the large crystallite sizes obtained via typical hydrothermal synthesis, resulting in mass-transfer issues.
Further improvement of this alloy's oxidation stability results from synergistic doping by a small amount (01 0.2% atomic) of active metals such as Hf and Y as well as Si (above 1%).
The nucleophilic character of organometallic compounds of active metals has many synthetic applications.
Finally, the role of the amount of the active metal and the amount of the excess of silicates inserted as anion were investigated.
Additional tests revealed that the deposited catalysts serve as a source of active metal for the reaction occurring in the liquid phase and that the yield of the coupling product is controlled by the amount of the leached-out metal.
This strong metal support interaction can restrict the agglomeration of active metal and avoid metal sintering during the reaction.
It has been demonstrated that small amounts of active lithium metal can be added to a lithium-ion (Li-ion) battery via the separator by using vacuum deposition techniques.
The amount of heavy metal uptake is directly associated with the total amount of active sites available on the adsorbent; a decrease in metallic nanoparticle dimensions increases their surface-to-volume ratio and consequently increases the active surface area for adsorption.
