Reports Outline Carbon Research Study Results from Dalhousie University (Small and wide angle X-ray studies of impregnated activated carbons)

July 11, 2014

By a News Reporter-Staff News Editor at Science Letter -- New research on Carbon Research is the subject of a report. According to news originating from Halifax, Canada, by NewsRx correspondents, research stated, "Small angle X-ray scattering (SAXS) and powder X-ray diffraction (XRD) measurements were made on CuO-impregnated activated carbons, prepared with and without an HNO3 co-impregnant, in order to determine the effect of impregnant loading and HNO3 content on impregnant distribution. A comprehensive matrix of 30 CuO-impregnated samples with five HNO3 concentrations and six impregnant loadings was prepared and studied."

Our news journalists obtained a quote from the research from Dalhousie University, "As a highlight, in Cu-based samples prepared with no HNO3, relatively small particle size CuO impregnant (approximately 3 nm) was observed at low impregnant loading and additional CuO appeared in large particles (>10 nm diameter) in meso and macropores as the impregnant loading increased. By contrast, when 4 M HNO3 was present during the impregnation, the largest impregnant particles found were less than 4 nm. Results from SAXS data were shown to be in good agreement with XRD and data obtained from nitrogen gas adsorption isotherms."

According to the news editors, the research concluded: "The combination of SAXS and XRD is shown to be a powerful combination in elucidating the nanostructure of impregnated activated carbons."
