Titanium Dioxide as a Catalyst Support in Heterogeneous Catalysis
The lack of stability is a challenge for most heterogeneous catalysts. During operations, the agglomeration of particles may block the active sites of the catalyst, which is believed to contribute to its instability. Recently, titanium oxide (TiO2) was introduced as an alternative support material for heterogeneous catalyst due to the effect of its high surface area stabilizing the catalysts in...

متن کاملA conceptual translation of homogeneous catalysis into heterogeneous catalysis: homogeneous-like heterogeneous gold nanoparticle catalyst induced by ceria supporter.
Translation of homogeneous catalysis into heterogeneous catalysis is a promising solution to green and sustainable development in chemical industry. For this purpose, noble metal nanoparticles represent a new frontier in catalytic transformations. Many challenges remain for researchers to transform noble metal nanoparticles of heterogeneous catalytic active sites into ionic species of homogeneo...
متن کاملInorganic-organic hybrid nanomaterial (Fe3O4@SiO2-AQ): A retrievable heterogeneous catalyst for the green synthesis of 4H-chromenes
Preparation of 4-aminiquinaldine grafted on silica-coated nano-Fe3O4 particles (Fe3O4@SiO2-AQ) as a novel retrievable heterogeneous nanocatalyst is described. This novel hybrid nanomaterial was applicated for the green synthesis of substituted 2-amino-4H-chromenes via the one-pot condensation reaction of an aldehyde, malononitrile ...
متن کاملHeterogeneous asymmetric catalysis*
Examples of enantioselective catalysts, including homogeneous supported catalysts and biphasic liquid/liquid, are described and compared. In the case of asymmetric hydride transfer, polythiourea was proven to be more efficient for ruthenium-catalyzed reduction of aryl ketones, although the iridium complexes gave rise to higher ee when using amino sulfonamide bound to a polystyrene matrix. In th...
