Testing catalytic activity of ruthenium(III) acetylacetonate in the presence of trialkylphosphite or trialkylphosphine in hydrogen generation from the hydrolysis of sodium borohydride
Open accessAbstract
Abstract Catalytic activity of Ru(acac) 3 in the presence of different phosphorus compounds (P(OMe) 3 , P(OPh) 3 , PPh 3 and dppe) was investigated for the first time in the hydrolysis of NaBH 4 . Phosphorus compound, usually known as poison in catalysis, is involved in the formation of a species which has higher catalytic activity in comparison with Ru(acac) 3 alone. Varying the phosphorus compound affects the catalytic activity and lifetime of the catalyst as well as the kinetics and the activation parameters of the hydrolysis of NaBH 4 . For all of the phosphorus compounds, the hydrogen generation was found to be zero-order with respect to the substrate concentration and first-order regarding the catalyst concentration. The catalyst system with P(OMe) 3 shows the highest catalytic activity and provides the largest total turnover number (TTON = 20,700 over 72 h) in the hydrolysis of NaBH 4 . The highest activation energy and enthalpy values were obtained for the catalyst with dppe ( E a = 59 ± 2, Δ H # = 60 ± 2 kJ/mol) while the lowest values were found for the catalyst system with PPh 3 ( E a = 46 ± 2, Δ H # = 43 ± 1 kJ/mol).

“there is no significant effect on the HGR by changing the amount of NaBH4, indicating that the reaction is a zero order reaction and is independent within a certain NaBH4 concentration range [21, 33, 34].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
