Softwood Kraft Pulp-Derived Carbon-Supported PtNi Catalysts for the Electrooxidation of Ethanol
(Frontiers Media S.A., 2020-11-10)
In this work, the biocarbons synthesized by fast pyrolysis at 350°C of raw (BK) and H3PO4 treated (TBK) fibrous fraction of non-bleached softwood kraft pulp has been proposed as novel supports for the deposition of PtNi ...
Influence of Pt addition to Ni catalysts on the catalytic performance for long term dry reforming of methane
(Elsevier Science, 2012-09)
The influence of Pt addition (in very low concentrations) to a Ni/(10%)/Al 2O 3 catalyst in its catalytic performance during long-term experiments of dry reforming of methane was studied. The monometallic Pt(0.5%)/Al 2O 3 ...
Pt-Co and Pt-Ni Catalysts of Low Metal Content for H2 Production by Reforming of Oxygenated Hydrocarbons and Comparison with Reported Pt-Based Catalysts
(Hindawi Limited, 2018-07)
New catalysts of Pt, PtNi, PtCo, and NiCo supported on Al2O3 were developed for producing hydrogen by aqueous phase reforming (APR) of oxygenated hydrocarbons. The urea matrix combustion technique was used for loading the ...
EXAFS characterization of PtNi bimetallic catalyst applied to glycerol liquid-phase conversion
(American Chemical Society, 2014-10)
The aim of this work is to evaluate the catalytic properties (activity, selectivity, and stability) of PtNi catalysts supported on Ce−Zr−α-Al2O3 (CZA) in the liquid-phase conversion of glycerol and to relate them to the ...
Characterization of the PtNi(111) surface and their influence on the selectivity of CC and COOH bonds: A DFT study
(Elsevier Science, 2015-10)
The interest to study the bimetallic surfaces falls on the significant differences properties with respect to their pure components. In this work, the density functional theory (DFT) is used to study bimetallic surface ...

The following doctoral thesis work presents a series of studies to address the synthesis, physical characterization and electrochemical evaluation of polyhedral PtNi catalysts supported on different carbon materials for ...
Hydrogen production from ethylene glycol reforming catalyzed by Ni and Ni–Pt hydrotalcite-derived catalysts
(Elsevier, 2016-12)
In this work, we report a study of the steam reforming (SR) and the aqueous phase reforming (APR) of ethylene glycol (EG) with catalysts based on Ni, prepared from hydrotalcite-like compounds. The Pt–Ni bimetallic catalyst ...
Isomerization of n-hexane on Pt-Ni catalysts supported on nanocrystalline H-BEA zeolite
(Elsevier Science, 2011-08)
The zeolite Beta used in this work consists of nanosized crystallites (20-30 nm) aggregates, determined by HRTEM analysis. The influence of the zeolite structure and crystallite size on the desorption rates of linear ...
