Highly Durable Heterogeneous Atomic Catalysts
Accounts of Chemical Research, 2022ConspectusSingle-atom catalysts (SACs), in which surface metal atoms are isolated on the surface of a support, have received a tremendous amount of attention recently because this structure would utilize precious metals fully, without occluding atoms inside nanoparticles, and enable unique surface reactions which typical nanoparticle catalysts cannot ...

Peels from tucuma, a widely consumed fruit in the North of Brazil, were calcined at 800 °C and employed as heterogeneous catalyst in biodiesel synthesis. The catalyst characterization by WDXRF showed it was mostly composed of K, P, Ca, and Mg.

Science, 1980
Proven catalysts exist in many different forms and with many different kinds of composition. An understanding of how catalysts function is beginning to emerge in a few areas, and some superior catalysts have been developed as a result of this knowledge. Applications of new techniques and disciplines should lead to impressive advances in the years ahead.

Heterogeneous hydrogenation catalysts
Russian Chemical Reviews, 1998The main types of heterogeneous catalysts used for hydrogenation, the methods for their preparation, and the structure and chemistry of their surfaces are considered, as well as the catalytic activity and the mechanism of action in the hydrogenation of unsaturated and aromatic compounds, of CO, and of carbonyl compounds and in the hydrorefining of ...

Hybrid chemoenzymatic heterogeneous catalysts
Current Opinion in Green and Sustainable Chemistry, 2021Through selected recent examples, we show that a new class of catalysts — hybrid chemoenzymatic heterogeneous catalysts — is currently emerging. These multifunctional solid materials have a bright forecast for the development of green and sustainable chemistry.
