چکیده
Environmental protection requires solving the problem of utilization and reduction CO CO2 emissions. Herein, Au/h-BN(O) Pt/h-BN(O) nanohybrids are thoroughly analyzed in oxidation hydrogenation reactions. The differ catalytic particle size distribution. particles smaller (1–6 nm) display a narrower distribution case Pt-based nanomaterials. exhibit high activity conversion carbon dioxide For both systems, oxidative state BN support affects activity. possible reaction mechanisms proposed based on DFT calculations. A charge density at Pt/h-BN interface increases oxygen absorption, thereby accelerating oxygen-associated chemical

Preparation of PdCu Alloy Nanocatalysts for Nitrate Hydrogenation and Carbon Monoxide Oxidation
Alloying Pd with Cu is important for catalytic reactions such as denitrification reaction and CO oxidation reaction, but understanding of the catalyst preparation and its correlation with the catalyst’s activity and selectivity remains elusive. Herein, we report the results of investigations of the preparation of PdCu alloy nanocatalysts using different methods and the catalytic properties of t...
متن کاملCatalytically active ceria-supported cobalt-manganese oxide nanocatalysts for oxidation of carbon monoxide.
A low-concentration cobalt (∼6 at%) and manganese (∼3 at%) bimetallic oxide catalyst supported on ceria nanorods (CoMnOx/CeO2), as well as its related single metal oxide counterparts (CoOx/CeO2 and MnOx/CeO2) was synthesized via a deposition-precipitation approach. The fresh samples after air-calcination at 400 °C were tested under the reaction conditions of CO oxidation, and showed the followi...
متن کاملCatalytic Hydrogenation of Carbon Monoxide
The hydrogenation of carbon monoxide and carbon dioxide on various steel catalysts was studied in the temperature range of 800" to 1,300'F. and at pressures from 5 to 30 atm. The feed gases (3.75 to 20 SCFH) were passed over a catalyst bed of 1/8-h. steel balls supported in a brass-lined reactor 0.81 in. in d i m . The percentage of carbon oxides in the feed was 30% in the runs using a Hz-COZ f...
متن کاملAccumulation of carbon monoxide and carbon dioxide in stored canola.
Production of carbon monoxide (CO) and carbon dioxide (CO(2)) from canola was studied in the laboratory and in commercial storage. Canola rapidly produced amounts of CO and CO(2) far exceeding those reported for dry cereal grain and dried peas and at levels dangerous to human health. In the laboratory, canola (5.8% m.c.) was stored in sealed flasks at 25, 35 and 45 degrees C for 12 weeks. Level...
متن کاملCatalytic Cyclocarbonylation in Compressed Carbon Dioxide: Pressure Influence of Carbon Monoxide and Carbon Dioxide
Among the current interests in organic synthesis are those reactions performing multiple C-C bond formation, in special when they undergo under catalytic conditions. Due to its properties, there is a growing interest on the use of compressed fluids (CF) as solvent media in catalytic processes. In this context, we present herein studies that aim to the development of a cleaner technology for the...
