Abstract

Pd–NiO hybridized with zeolite and multiwalled carbon nanotube appeared as highly effective electrocatalyst in methanol oxidation reaction.

Fe2O3 Nanocatalysts Supported on Zeolite-Y for the Selective Synthesis of C2 Di-Indolyl Indolones and Isatins

“…19 Zeolite-Y is known to be an excellent hard templating agent for shaping and controlling the formation of different nanomaterials such as carbon nanomaterials and metal oxide nanoparticles. 19,20 Our group has investigated different metal complexes encapsulated in zeolite-Y and studied their activity for different organic transformations. 21−24 It was also observed that zeolite-Y-supported metal oxide nanoparticles showed good catalytic activity in the reactions such as benzyl alcohol oxidation, C−C coupling reactions, and methanol oxidation reaction.…”

Dual Matrix Influence on Ni(II) Rich Hybrid Catalyst for Electrochemical Methanol Oxidation Reaction

“…Although the DMFC technology has able to attract the eyes of the scientific community buts its commercialization is restricted by certain challenges involve in the methanol oxidation process. Among which the CO poisoning, methanol tolerance, slow kinetics, need of metal catalyst with high cost like Pt and Pd are major problems associated with methanol oxidation reaction (MOR) [22–24] …”

“…Like the Ni(OH) 2 , MnO 2 have some advantages‐ it acts as a suitable promoter, help in improving the kinetics of MOR and prevents the catalyst from agglomeration [40,41] . Along with zeolite‐Y, Ni(OH) 2 and MnO 2 , MWCNT also participate in enhancing the electronic conductivity and the overall electrocatalytic activity of the nanocatalyst by providing the secondary porosity for mass transport [23,24] . Therefore, taking the advantages of zeolite‐Y, Ni(OH) 2 , MnO 2 and MWCNT herein, we tried to develop a multicomponent hybrid electrocatalyst represented as MnO 2 −Ni(OH) 2 ‐Y/MWCNT for effective methanol oxidation reaction in alkaline medium.…”

Pt/Mn3O4 cubes with high anti-poisoning ability for C1 and C2 alcohol fuel oxidation

“…3,4 Therefore, attention has been paid to developing efficient catalysts to reduce the Pt loading and increase their catalytic activity. 5 Earth-abundant and non-precious metals have been employed to tune the electronic structure and chemical state of Pt in order to improve its catalytic performance via the ligand effect and electronic effect. 6,7 Because poisoning intermediates such as CO species that adsorb onto the Pt active sites severely reduce the catalytic performance, oxophilic components, such as transition metal oxides, have been introduced as assisting promoters, offering oxygen-containing species that can facilitate the catalytic reactions.…”

“…6,7 Because poisoning intermediates such as CO species that adsorb onto the Pt active sites severely reduce the catalytic performance, oxophilic components, such as transition metal oxides, have been introduced as assisting promoters, offering oxygen-containing species that can facilitate the catalytic reactions. 5,8,9 For example, the surface engineering of the Pt or Pd and CeO 2 particles can effectively promote methanol oxidation via a strong electronic effect and the abundant oxygen vacancies offered by CeO 2 . 10,11 Hausmannite (Mn 3 O 4 ) has received increasing interest with regards to molecular adsorption and catalysis, as the oxophilicity of Mn 3 O 4 is favorable for water adsorption and dissociation according to density-functional theory calculations.…”
