Cu,Zn,Al layered double hydroxides as precursors for copper catalysts in methanol steam reforming – pH-controlled synthesis by microemulsion technique [PDF]
, 2012 By co-precipitation inside microemulsion droplets a Cu-based catalyst precursor was prepared with a Cu:Zn:Al ratio of 50:17:33. A pH-controlled synthesis was applied by simultaneous dosing of metal solution and precipitation agent.

Effect of Nano Hydrotalcite on the Aging Resistance of a High Binder Content Stone Mastic Asphalt
Applied Sciences, 2021 Hydrotalcite, a type of layered double hydroxide (LDH), reveals an interesting potential for the modification of bitumen. The LDH can induce a barrier effect that prevents the loss of volatiles, retards oxidation, and protects against ultraviolet ...

FTIR study of hydrotalcite [PDF]
Acta Chimica Slovaca, 2018 Abstract The aim of the research was the study of aluminium-magnesium hydrotalcite by FTIR analysis and detection of differences in structure due to calcination. Three types of samples were analysed. In the first two samples, cobalt was added into the structure and the third sample contained nickel and zinc.

Production of hydrogen by unmixed steam reforming of methane [PDF]
, 2008 Unmixed steam reforming is an alternative method of catalytic steam reforming that uses separate air and fuel–steam feeds, producing a reformate high in H2 content using a single reactor and a variety of fuels. It claims insensitivity to carbon formation
