ZnOCr2O3 + ZSM-5 catalyst with very low Zn/Cr ratio for the transformation of synthesis gas to hydrocarbons
TL;DR: In this article, three Zn Cr mixed oxide plus ZSM-5 compound catalysts with different compositions covering a wide range of Zn/Cr atomic ratios (0.064 to 1.913) were tested under different experimental conditions: temperature ranged from 356 to 410°C, pressure from 3.60 to 4.49 MPa and space velocity from 0.2 to 3.0 mmol reactants/(g cat min).

TPD, TPR and DRIFTS studies of adsorption and reduction of NO on La2O3 dispersed on Al2O3
TL;DR: The surface properties of La 2 O 3 supported by temperature-programmed desorption (TPD) showed features more and more similar to unsupported La 2 o 3 as the La o 3 loading increased as discussed by the authors.

Adsorption of CO and NO on NiO(111)Ni(111) surface studied by infrared-visible sum frequency generation spectroscopy
Athula Bandara,Shinsaku Dobashi,Jun Kubota,Ken Onda,Akihide Wada,Kazunari Domen,Chiaki Hirose,Satoru S. Kano +7 more
TL;DR: In this paper, the infrared-visible sum frequency generation (SFG) measurements were compared with those of infrared reflection absorption spectroscopy, and the results indicated that the CO molecule was inclined to the surface whereas the tilt angle of NO from the surface normal was smaller than that of CO. The adsorption sites of CO and NO molecules are located on the slopes of trigonal microfacets formed by the reconstruction of the NiO(111) surface.
