Abstract

Start with the transition state: Zeolites catalyze a wide range of industrial reactions, but identifying the reactions that they catalyze well tends to be done by trial and error. Gallego et al.propose a way to rationalize the process by using structure-directing agents that act as scaffolds for creating the zeolite pores and channels (see the Perspective by Millini). They picked molecules that mimic the transition states for reactions such as the isomerization of ethylbenzene into xylene, and they successfully identified catalysts with improved reactant conversion and product selectivity.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The rational design of OSDAs in the search for particular zeolites has given good results in some cases.

    “However, the rational design of OSDAs in the search for particular zeolites has given good results in some cases.57,97−100”
  • Recent advances in data mining and artificial intelligence have allowed computational prediction to some extent of which OSDAs may lead to the crystallization of targeted zeolite structures.

    “In this sense, recent advances in data mining and artificial intelligence have allowed us to computationally predict to some extent which OSDAs may lead to the crystallization of targeted zeolite structures.97,99,101”
  • Al distribution in the zeolite framework can be controlled by modifying the synthesis conditions.

    “It has been found that selectivity in many acid-catalyzed reactions by Al-containing zeolites strongly depends on the Al distribution in the zeolite framework, which can be controlled by modifying the synthesis conditions.”
  • The reduction of average crystal size of a zeolite is mostly done directly by hydrothermal synthesis promoting nucleation versus crystal growth.

    “The reduction of average crystal size of a zeolite is mostly done directly by hydrothermal synthesis promoting nucleation versus crystal growth,99,134−138 although other nonconventional methods have been applied as well.139”
  • Selectivity in many acid-catalyzed reactions by Al-containing zeolites strongly depends on the Al distribution in the zeolite framework.

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.
