1. IN SITU DRIFTS/MS STUDIES ON THE INTERACTION OF METHANOL AND ETHYL ACETATE OVER MG-LA CATALYST
The surface intermediates formed on the Mg-La catalyst (molar ratio 1:1) were studied through temperature-programmed desorption (TPD) and diffuse reflectance infrared Fourier transform spectroscopy coupled to mass spectrometry (DRIFTS-MS) using methanol (MeOH) and ethyl acetate (EA) as probe molecules. TPD results showed that the products formed from adsorbe

2. De-NOx Performance and Mechanism of Mn-Based Low-Temperature SCR Catalysts Supported on Foamed Metal Nickel
A series of manganese-based catalysts supported on foamed metal nickel (FMN) with various Mn/Ni ratios was prepared for low-temperature selective catalytic reduction (SCR) of NO with NH3 (NH3-SCR). The effects of calcination temperature, amount of added Mn, optimal operating conditions, and H2O on the elimination of nitrogen oxides (de-NOx) performance of ca

3. Adsorción y oxidación de monóxido de carbono en una lamina de ß-grafino: Estudio teórico
ABSTRACT This work presents a study, based on the Density functional theory (DFT), of the adsorption and oxidation of CO on a free platinum catalyst constituted from a sheet of Graphyne. Graphyne is a new allotrope of carbon, its structure is two-dimensional and is constituted by a monolayer of carbon atoms with sp-sp2 hybridization. Depending on the differe

4. Acilação de Friedel-Crafts do 2-metoxinaftaleno usando o ácido dodecafosfotúngstico suportado em sílica (HPW/SiO2) como catalisador e acetonitrila como solvente
The synthesis of fine chemicals intermediates using Friedel-Crafts acylation is one of the most important methods in chemical technology. In this work, the acylation of 2-methoxynaphthalene with acetic anhydride using a silica-supported dodecatungstophosphoric acid catalyst (HPW/SiO2) and acetonitrila as solvent was studied, showing that this reaction is a f

5. ELETROOXIDAÇÕES DE ACETALDEÍDO COMUM E ETANOL ISOTOPICAMENTE MARCADO (H3 13C12CH2OH) EM SUPERFÍCIE DE PLATINA ACOMPANHADAS POR FTIRS in situ / Electrooxidation of acetaldehyde common and ethanol Isotope-labeled compounds (H3 13C_12CH2OH) in surface accompanied by platinum FTIRS in situ.
Este trabalho trata das reações de eletrooxidações de acetaldeído comum e etanol isotopicamente marcado, ambas reações em superfície de platina policristalina em meio de ácido perclórico, HClO4, 0,1 Mol L-1, com a utilização de técnicas eletroquímicas convencionais e espectroscopia (FTIRS in situ). Para o acetaldeído, essa reação foi estuda
