NH4F Modified Al-SBA-15 Materials for Esterification of Valeric Acid to Alkyl Valerates
(MDPI, 2019)
Al-SBA-15 materials were functionalized by ball milling with several niobium loadings (0.25–1 wt.%) and/or with several F- loadings, using NH4F as a precursor. The catalysts synthesized in this study were characterised by ...
Sol-Gel Immobilisation of Lipases: Towards Active and Stable Biocatalysts for the Esterification of Valeric Acid
(MDPI, 2018)
Alkyl esters are high added value products useful in a wide range of industrial sectors.
A methodology based on a simple sol-gel approach (biosilicification) is herein proposed to encapsulate
enzymes in order to design ...
Bentonites Modified with Phosphomolybdic Heteropolyacid (HPMo) for Biowaste to Biofuel Production
(MDPI, 2019)
Two bentonites from Paraíba (Northeastern Brazil) were impregnated with heteropoly phosphomolybdic H3PMo12O40 (HPMo). The materials produced were characterized by various techniques such as N2 adsorption-desorption (specific ...
