The Effect of SnO2 and Rh on Pt Nanowire Catalysts for Ethanol OxidationAbstract In this study, we synthesized Pt-Rh nanowires (NWs) through chemical reduction of metallic precursors using formic acid at room temperature, excluding the use of surfactants, templates, or stabilizing agents. These NWs were supported on two substrates: carbon (Vulcan XC-72R) and carbon modified with [...] 103 473 |
Synthesis of NaA Zeolite: Conventional Route and Green RouteAbstract The research describes a sustainable approach for the synthesis of zeolite NaA using kaolin as an alternative source of silica. The main objective of this research was to prepare NaA zeolite using metakaolin derived from kaolin from the state of Rio Grande do Norte, Brazil, as an alternative source [...] 116 868 |

NaY Zeolite Synthesis from Vermiculite and Modification with SurfactantAbstract This work focuses on preparing NaY zeolite using alternative sources of silica and modifying the zeolite with the surfactant cetyltrimethylammonium bromide. Two different hydrothermal synthesis routes were employed: the conventional method using sodium silicate as the silica source, and the other is [...] 162 1435 |
Synthesis of SAPO-34 Zeolite Membrane: Influence of Sources of SilicaAbstract The research described the production and characterization of various materials, particularly alpha-alumina ceramic supports, zeolite SAPO-34, and zeolite membranes. Ceramic supports were manufactured through dry uniaxial compaction. Sintering of the supports was carried out at 1300°C for 2 h. SAPO- [...] 139 1391 |

Abstract To improve CH4 and H2 formation from CO2 photoreduction using non-organic, non-laborious, and inexpensive photocatalysts, we have prepared two surface-silicate-modified TiO2 catalysts: P25-SiO2< [...] 205 1675 |
Nano Metal Oxide Frameworks (NOF): Development of New Heterogeneous Catalyst for the Synthesis of Furan Derivatives from GlucoseAbstract A surface modification approach has prepared a nanostructured organic framework connecting two metal oxide NPs. The surface modifier attached two metal oxide NPs via molecular interaction to generate modular structures of fiber, rod, or sponge materials. Thus, obtained hybrid sy [...] 314 1839 |

Abstract This paper investigates how the aggregation of bimetallic nanoparticles (NPs) influences the electronic condition of the surface adsorption site and, hence, the performance of materials during the electrooxidation of fuels in an alkaline medium. First, we synthesized Pt-Ni NPs in three configuration [...] 264 1805 |
