Abstract

In many aspects, similitude exists between man-made catalysts and enzymes. Can scientific insight into this similitude stimulate new research directions in catalysis? More precisely, can the understanding of the mechanisms of activity control in enzymes suggest new advances for man-made catalysts? Indeed, it is already possible to design catalysts with (i) new structures (e.g. presence of several phases) and (ii) a better balance between the roles of the different components. The ambition is to keep the essential advantages of solids as catalysts, in particular robustness, easy separation from products, and tolerance to high temperatures, while adding the advantages typical of enzymes, like more activity, allostery, and more precise control of selectivity, in particular enantioselectivity. The ambition is to build a bridge between robust man-made functional solids and fragile but extremely selective enzymes. For that, results from a line of the work in our group will be used.

Effect of secondary additives on the properties of vanadium‑aluminum mixed oxide tableted catalysts used in the oxidation of propane
2021, Powder Technology
Citation Excerpt :
Explaining the behavior of multicomponent catalysts is still an unresolved issue in catalysis science since most investigations are made for understanding model systems. In the past, however, the extensive works of the late Prof. Delmon et al. [75,76] aimed explaining such effects by postulating the so-called remote control theory in which one catalytic phase would be responsible for activating oxygen molecules (or hydrogen) and then spilling it over another catalytic phase. Where, the rate of spillover would determine the reactivity of the system and the dynamics of the reaction.
The effect of adding secondary additives for tableting vanadium‑aluminum mixed-oxides, VAlO, on key physicochemical properties and on the catalytic performance in propane oxidation was investigated. Graphite was used as the primary shaping agent. The secondary additives were MgO, silica, BN, sepiolite, and ZnO. The hardness, fracture strength, and particle shape of the secondary additives were associated to the changes of the mechanical strength and porosity of the tablets. There was a compromise between mechanical strength and loss of mesoporosity and surface area. Meanwhile, the additives did not establish a chemical interaction with the VAlO material. Therefore, the secondary additives may act as co-catalysts during propane oxidation. BN and sepiolite were best for promoting both the reactivity of the catalytic formulations and the production of propene. This promotion may be due to the combination of a redox mechanism over the VAlO phase and to a surface radical mechanism occurring over the active moieties of BN and sepiolite.
Hydrogen spillover effect between Ni<inf>2</inf>P and MoS<inf>2</inf> catalysts in hydrodesulfurization of dibenzothiophene
2015, Ranliao Huaxue Xuebao/Journal of Fuel Chemistry and Technology
The hydrodesulfurization of dibenzothiophene over physically separated Ni₂P//MoS₂ catalyst beds was investigated. The results indicated that the hydrogen spillover effect appears between the Ni₂P/Al₂O₃ and MoS₂/Al₂O₃ catalysts in the hydrodesulfurization reaction, which can significantly enhance the concentration of active sites and the hydrodesulfurization rate over the MoS₂ catalyst. The spillover factor on Ni₂P//MoS₂ is slightly higher than that on NiS_x//MoS₂, due to the higher hydrogen dissociation activity of Ni₂P; as a result, Ni₂P is a superior promoter to NiS_x for the MoS₂ catalyst.

Vennestrøm et al. have recently reported the combination of glucose oxidase with titanium silicalite-1 to utilize the by-product of one reaction (H2O2) for the second one (epoxidation of allyl alcohol) [16]. Our idea, which can be expressed by “a hybrid of an enzyme catalyst with artificial catalysts for the same reaction”, has come out from the instructive and inspiring review article presented by Professor Bernard Delmon [17]. He has proposed a bridged system between man-made functional solids and enzyme.
Glucose oxidation by enzyme takes place in neutral aqueous solution at room temperature, producing gluconic acid in equilibrium with gluconate, while gold catalysts exhibit much higher catalytic activity but in alkali solution to produce sodium gluconate. The combination of glucose oxidase with selected gold catalysts such as Au/ZrO₂ and Au/NanoDiamond led to improved catalytic performance in neutral solution at room temperature. Gold nanoparticles supported on ZrO₂ decomposed hydrogen peroxide (H₂O₂) formed by the oxidation of glucose and depressed the damage of glucose oxidase by H₂O₂. In addition, Au/ZrO₂ utilized H₂O₂ produced by the enzyme to oxidize glucose to gluconic acid. In contrast, gold nanoparticles supported on NanoDiamond were active only for the decomposition of H₂O₂, while the presence of NanoDiamond itself could encourage glucose oxidase for the selective oxidation.

2013, Ranliao Huaxue Xuebao/Journal of Fuel Chemistry and Technology
The synergetic effect between Ni₂P/Al₂O₃ and MoS₂/Al₂O₃ catalysts on their performance in the hydrodenitrogenation of quinoline was proved by a simplified experimental design and explained by the remote control model through a migration of hydrogen spillover. The results indicated that the synergism factor of Ni₂P and MoS₂ is slightly higher than that of NiS_x and MoS₂; it decreases with the increase of reaction temperature. Since the spillover hydrogen with Ni₂P can increase the amount of hydrogenation active sites of MoS₂, the hydrogenation rate of 1,2,3,4-tetrahydroquinoline and 5,6,7,8-tetrahydroquinoline to decahydroquinoline over the Ni₂P/Al₂O₃ and MoS₂/Al₂O₃ catalyst system is then greatly enhanced; as a result, Ni₂P is a superior promoter for MoS₂ catalyst for hydrodenitrogenation.

Synergetic effect between sulfurized Mo/γ-Al<inf>2</inf>O<inf>3</inf> and Ni/γ-Al<inf>2</inf>O<inf>3</inf> catalysts in hydrodenitrogenation of quinoline
2011, Journal of Natural Gas Chemistry
An evidence for the synergetic effect between the stacked bed of Mo/γ-Al₂O₃ and Ni/γ-Al₂O₃ in the hydrodenitrogenation (HDN) reaction of quinoline has been provided in this paper. The synergism factor decreases when the reaction temperature increases (280–340°C). The synergetic effect leads to improve the hydrogenation activity for the stacked bed compared with the single Mo/γ-Al₂O₃ bed, which may be attributed to the generation of hydrogen spillover on the Ni/γ-Al₂O₃ catalyst.
