The Laboratory of Catalysis(LC) tem has access to a broad range of techniques at the Nuclear and Technological Institute. The facilities includes analytical techniques for molecular and macromolecular characterization such as NMR, FTIR, Mass Spectrometry, Elemental Analysis (C, H, N, S), Thermal Analysis (TG, DSC), X-Ray (powder and single crystal), Gas Chromatography (CG, with TCD and FID detectors), etc.
Several reactor systems are available at the LC, including pressure reactors (autoclaves) and plug-flow type reactors (Pyrex and quartz) for measurements at atmospheric pressure. Facilities for CO safety manipulation and techniques such as TPR and TPD for catalysts characterization are also installed
On line GC analysis(TCD e FID) is the main technique used to follow the catalytic reactions. Three GC are available (Agilent 4890D with TCD, Agilent 7820, with FID and Shimadzu 9A, with TCD and FID) either for reactivity studies or for thermal characterization of the catalysts (TPR, TPD of selected molecules).
Resource facilities for the synthesis of ligands and compounds under inert atmosphere, namely glove boxes, are also on hand. The LC has also access to unusual facilities for catalysts preparation such as synthesis in liquid ammonia.
The LC has been doing research in several areas. The catalytic reactions and process under investigation are based on the activation of pollutant C1 substrates such as CH4 and CO2. The LC is also engaged in partnership projects with the industry.
A brief summary of selected projects is given below.
Oxidative Coupling of Methane using f Block Element Intermetallic Compounds as Catalytic Precursors a
The main objective of this project was to study LnCu2 (Ln=La, Ce, Pr, Nd, Gd, Tm) and AnCu2 (An=Th, U) intermetallic compounds as catalyst precursors for the oxidative coupling of methane to C2 hydrocarbons (C2H6 and C2H4), with high ethylene selectivity.
