Novel TiO catalyst carriers with high thermostability for selective catalytic reduction of NO by NH.

Catal Today 2019 May 24;327:279-287. Epub 2018 Apr 24.

Department of Chemistry and Biochemistry, Environmental Science & Engineering, and Biomedical Engineering, University of Texas at EL Paso, EL Paso, TX 79968, USA.

A series of TiO catalyst carriers with ceria additives were prepared by a precipitation method and tested for selective catalytic reduction (SCR) of NO by NH. These samples were characterized by XRD, N-BET, NH-TPD, H-TPR, TEM, XPS and DRIFTS, respectively. Results showed that the appropriate addition of ceria can enhance the catalytic activity and thermostability of TiO catalyst carriers significantly. Read More

Silver-modified octahedral anatase particles as plasmonic photocatalyst.

Catal Today 2018 Jul;310:19-25

Institute for Catalysis. Hokkaido University, N21, W10, 001-0021, Sapporo, Japan.

Octahedral anatase particles (OAPs) were modified with silver nanoparticles (NPs) by photodeposition method. The properties of OAPs influenced the properties of silver deposits, and thus the photocatalytic activity of the obtained silver-modified OAPs. Photocatalytic activities were tested under UV and vis irradiation for oxidative decomposition of acetic acid and oxidation of 2-propanol, respectively. Read More

Coordination chemistry insights into the role of alkali metal promoters in dinitrogen reduction.

Catal Today 2017 May 16;286:21-40. Epub 2016 Aug 16.

Department of Chemistry, Yale University, New Haven, CT 06511 USA.

The Haber-Bosch process is a major contributor to fixed nitrogen that supports the world's nutritional needs and is one of the largest-scale industrial processes known. It has also served as a testing ground for chemists' understanding of surface chemistry. Thus, it is significant that the most thoroughly developed catalysts for N reduction use potassium as an electronic promoter. Read More

Reduction of CO using a Rhenium Bipyridine Complex Containing Ancillary BODIPY Moieties.

Catal Today 2014 Apr;225:149-157

Department of Chemistry and Biochemistry, University of Delaware, Newark, DE, 19716.

The reduction of carbon dioxide to chemical fuels such as carbon monoxide is an important challenge in the field of renewable energy conversion. Given the thermodynamic stability of carbon dioxide, it is difficult to efficiently activate this substrate in a selective fashion and the development of new electrocatalysts for CO reduction is of prime importance. To this end, we have prepared and studied a new -Re(CO) complex supported by a bipyridine ligand containing ancillary BODIPY moieties (). Read More

A modified expression of the major hydrolase activator in () changes enzymatic catalysis of biopolymer degradation.

Catal Today 2011 Jun;167(1):122-128

Gene Technology, Gene Technology and Applied Biochemistry, Institute of Chemical Engineering, TU Wien, Getreidemarkt 9/166/5/2, A-1060 Wien, Austria.

(anamorph ) is a saprophytic fungus that produces hydrolases, which are applied in different types of industries and used for the production of biofuel. A recombinant strain, which constantly expresses the main transcription activator of hydrolases (Xylanase regulator 1), was found to grow faster on xylan and its monomeric backbone molecule d-xylose. This strain also showed improved ability of clearing xylan medium on plates. Read More

Iron(II)-catalyzed enhancement of ultrasonic-induced degradation of diethylstilbestrol (DES).

Catal Today 2005 Apr;101(3-4):369-373

Department of Chemistry and Biochemistry, Florida International University, Miami, FL 33199, USA.

The oxidation of the endocrine disruptor, diethylstilbestrol (DES) in aqueous media by ultrasound is significantly enhanced by Fe(II) catalyst. The observed enhancement is likely the result of increased levels of hydroxyl radicals from the iron-promoted reduction of the hydrogen peroxide produced during ultrasonic irradiation. The degradation is effective over a range of concentrations and is consistent with pseudo first-order kinetics. Read More
