CO tolerance and durability study of PtMe(Me = Ir or Pd) electrocatalysts for H2-PEMFC application
(2021)In the present work, carbon supported PtMe (Me = Ir or Pd) electrocatalysts, with different atomic ratios (Pt/Me (20 wt%) = 3:1, 1:1, 1:3), are thoroughly investigated towards CO tolerance and durability, as anode and ... -
Durability indicators of SCC towards performance-based specifications for the durability of SCC
(2010)The fundamental principle behind the development of SCC has been the nanoscale tailoring of cementitious matrices. Although self-compacting concrete (SCC) is currently used in many countries, there is a fundamental lack ... -
Durability of accoya wood in ground stake testing after 10 years of exposure in Greece
(2020)In this research, acetylated wood (Accoya) was tested in ground contact in central Greece. After ten years of exposure during a ground stake test, acetylated pine wood (Pinus radiata) stakes, with a 20% acetyl weight gain, ... -
Enhanced electrocatalytic overall water splitting over novel one-pot synthesized Ru–MoO3-x and Fe3O4–NiFe layered double hydroxide on Ni foam
(2021)Herein, two novel electrocatalysts are simultaneously grown on Ni foam (NF) through a one-step hydrothermal method. The as-prepared Ru–MoO3-x NF exhibits good performance for HER with low overpotentials of 12 mV at 10 mA ... -
Enhanced oxygen reduction and methanol oxidation reaction over self-assembled Pt-M (M = Co, Ni) nanoflowers
(2022)Herein, we introduce a facile approach to synthesize a unique class of Pt-M (M = Ni, Co) catalysts with a nanoflower structure for boosting both oxygen reduction reaction (ORR) and methanol oxidation reaction (MOR). By ... -
Facile synthesis of bimetallic Pt-Pd symmetry-broken concave nanocubes and their enhanced activity toward oxygen reduction reaction
(2019)In the present work, we are reporting a facile one-pot synthesis route to get Pt-Pd symmetry-broken concave nanocube (SBCNCs) structures in N, N-dimethylformamide (DMF) solutions under the effect of iodide ions and Poly ... -
Furfurylation of tropical wood species with and without silver nanoparticles: Part II: Evaluation of wood properties
(2021)The purpose of the work was to assess the combined effect of furfurylation, along with the addition of silver nanoparticles (NPsAg), on the thermal stability, density, water absorption, hardness and biological durability ... -
Highly stable Pt-Co nanodendrite in nanoframe with Pt skin structured catalyst for oxygen reduction electrocatalysis
(2021)A novel self-etched engineering of Pt-Co nanodendrite in nanoframe (Pt-Co ND-NF) synthesized through a simple one-pot approach, for the first-time. The modulation mechanism of Pt-Co ND-NF formation is established by ... -
Iron oxide@graphitic carbon core-shell nanoparticles embedded in ordered mesoporous N-doped carbon matrix as an efficient cathode catalyst for PEMFC
(2020)Developing electrocatalysts with high activity and long-term stability towards oxygen reduction reaction (ORR) in acidic media is still an important topic. However, most of the already reported non-precious-metal catalysts ... -
Novel Mn-/Co-N x Moieties Captured in N-Doped Carbon Nanotubes for Enhanced Oxygen Reduction Activity and Stability in Acidic and Alkaline Media
(2021)Fe-N-C-based electrocatalysts have been developed as an encouraging substitute compared to their expensive Pt-containing equivalents for the oxygen reduction reaction (ORR). However, they still face major durability ... -
ZIF-Mg(OH)2 Dual Template Assisted Self-Confinement of Small PtCo NPs as Promising Oxygen Reduction Reaction in PEM Fuel Cell
(2022)Traditional calcination usually causes sintering of Pt, which diminishes Pt exposure in proton exchange membrane fuel cell (PEMFC) electrodes. In the present work, a facile self-confined method for synthesizing highly ...
