Microheterogeneous Catalysis [PDF]

Molecules, 2010
The catalytic effect of micelles, polymers (such as DNA, polypeptides) and nanoparticles, saturable receptors (cyclodextrins and calixarenes) and more complex systems (mixing some of the above mentioned catalysts) have been reviewed. In these microheterogeneous systems the observed changes in the rate constants have been rationalized using the ...

Novel Ni/Ce(Ti)ZrO₂ Catalysts for Methane Dry Reforming Prepared in Supercritical Alcohol Media

Energies, 2020
To achieve a high activity and coking stability of nickel catalysts in dry reforming of methane, materials comprised of ceria–zirconia doped by Ti were investigated as supports.

IDPi Catalysis [PDF]

Angewandte Chemie International Edition, 2019
AbstractHigh acidity and structural confinement are pivotal elements in asymmetric acid catalysis. The recently introduced imidodiphosphorimidate (IDPi) Brønsted acids have met with remarkable success in combining those features, acting as powerful Brønsted acid catalysts and “silylium” Lewis acid precatalysts in numerous thus far inaccessible ...

Anion–π catalysis on carbon allotropes

Beilstein Journal of Organic Chemistry, 2023
Anion–π catalysis, introduced in 2013, stands for the stabilization of anionic transition states on π-acidic aromatic surfaces. Anion–π catalysis on carbon allotropes is particularly attractive because high polarizability promises access to really strong

Catalysis of entanglement and other quantum resources [PDF]

Rep. Prog. Phys. 86, 116002 (2023), 2022
In chemistry, a catalyst is a substance which enables a chemical reaction or increases its rate, while remaining unchanged in the process. Instead of chemical reactions, quantum catalysis enhances our ability to convert quantum states into each other under physical constraints.

Processive Catalysis [PDF]

Angewandte Chemie International Edition, 2014
AbstractNature’s enzymes are an ongoing source of inspiration for scientists. The complex processes behind their selectivity and efficiency is slowly being unraveled, and these findings have spawned many biomimetic catalysts. However, nearly all focus on the conversion of small molecular substrates.

Challenges in Plasmonic Catalysis [PDF]

ACS Nano 14 (2020) 16202-16219, 2021
The use of nanoplasmonics to control light and heat close to the thermodynamic limit enables exciting opportunities in the field of plasmonic catalysis. The decay of plasmonic excitations creates highly nonequilibrium distributions of hot carriers that can initiate or catalyze reactions through both thermal and nonthermal pathways. In this Perspective,
