Abstract Ilmenite is a mineral whose crystallinity can be altered by chemical treatment, producing TiO2 and iron and titanium-based metal nanocomposites, which are applicable mainly for photocatalysis. Porous and crystalline biomass-derived carbon materials include graphene oxide, redu [...] 414 3484 |
A Remarkable Pt Doped CNT Catalyst as a Double Functional Material: Its Application for Hydrogen Production and SupercapacitorAbstract In this study, by producing bifunctional material, hydrolysis, and supercapacitor applications were investigated. The carbon nanotube-supported Pt catalyst was prepared using the sodium borohydride (NaBH4) reduction. Surface characterization of the synthesized Pt/CNT catalyst [...] 412 3244 |
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 [...] 608 3698 |
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 [...] 662 4693 |

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 [...] 746 4752 |
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- [...] 591 4900 |
