Development of a Polyphenol Oxidase Biosensor from Jenipapo Fruit Extract (Genipa americana L.) and Determination of Phenolic Compounds in Textile Industrial Effluents
(MDPI, 2018)
In this work, an innovative polyphenol oxidase biosensor was developed from Jenipapo
(Genipa americana L.) fruit and used to assess phenolic compounds in industrial effluent samples
obtained from a textile industry located ...
Catalytic Conversion of Biomass
(MDPI, 2016)
Petroleum, natural gas and coal supply most of the energy consumed worldwide and their massive utilization has allowed our society to reach high levels of development in the past century. The shift towards a bio-based ...
Novel Bifunctional Mesoporous Catalysts Based on Preyssler Heteropolyacids for Green Pyrrole Derivative Synthesis
(MDPI, 2018)
In this paper, we report the synthesis of Preyssler heteropolyacids supported on mesoporous
alumina in order to obtain materials with acid–base properties. A series of pyrrole derivatives were
synthesized using a suitable ...
Ternary Hydrotalcites in the Multicomponent Synthesis of 4H-Pyrans
(MDPI, 2020)
Lamellar double hydroxides (LDH) with double divalent cations were synthesized by the co-precipitation method and studied in the multicomponent synthesis of 4H-pyrans. The solids obtained were characterized by X-ray ...
Simple Preparation of Novel Metal-Containing Mesoporous Starches
(MDPI, 2013)
Metal-containing mesoporous starches have been synthesized using a simple and
efficient microwave-assisted methodology followed by metal impregnation in the porous
gel network. Final materials exhibited surface areas >60 ...
Acetylation of Eugenol over 12-Molybdophosphoric Acid Anchored in Mesoporous Silicate Support Synthesized from Flint Kaolin
(MDPI, 2019)
A new prepared catalyst, 12-molybdophosphoric acid (HPMo) anchored to the mesoporous aluminosilicate AlSiM, synthesized from Amazon kaolin, was characterized and used as a heterogeneous acid catalyst for the production of ...
An Efficient and Recyclable Nanoparticle-Supported Cobalt Catalyst for Quinoxaline Synthesis
(MDPI, 2015)
The syntheses of quinoxalines derived from 1,2-diamine and 1,2-dicarbonyl compounds
under mild reaction conditions was carried out using a nanoparticle-supported cobalt catalyst.
The supported nanocatalyst exhibited ...
Continuous-Flow Hydrogenation of Methyl Levulinate Promoted by Zr-Based Mesoporous Materials
(MDPI, 2019)
Several Zr-based materials, including ZrO2 and Zr-SBA-15, with different silicon/zirconium molar ratios, and ZrO2/Si-SBA-15 (where SBA-15 stands for Santa Barbara Amorphous material no. 15), have been prepared as hydrogenation ...
Efficient Enzyme-Free Biomimetic Sensors for Natural Phenol Detection
(MDPI, 2016)
The development of sensors and biosensors based on copper enzymes and/or copper
oxides for phenol sensing is disclosed in this work. The electrochemical properties were studied
by cyclic and differential pulse voltammetry ...
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 ...
