Abstract:The catalytic activity of layered double hydroxide (LDH) and the aqueous solution absorption capacity of ureasil polyethylene oxide (U-PEO) were combined to produce an easily recyclable solidliquid (S-L) reactor (U-PEO:LDH). Scanning electron microscopy (SEM), X-ray diffraction (XRD) and small-angle X-ray scattering (SAXS) of LDH (CuZnAl), U-PEO, and U-PEO:LDH confirmed the layered structure of the catalyst and evidenced its inclusion in the free volume of U-PEO matrix. The catalytic activity of the CuZnAl in … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
