Nov 03, 2020· In this work, a novel sponge-like platinum nanostructures are fabricated on a nickel foam and utilized for electro-oxidation of methanol. The fabrication method consisted of three steps: the electrodeposition of mesoporous silica film onto the Ni-foam as a template, the galvanic replacement of Pt nanostructures into the silica-templates/Ni-foam, and finally removing the silica templates.

Improvement of cell performance in catalyst layers with

Jan 13, 2020· Recently, Takenaka et al. have developed silica-coated Pt catalysts (SiO 2-Pt/Cs) at the cathode for PEFCs, and their catalysts have maintained a high activity for the ORR during the durability tests. By TEM images of Takenaka et al., most Pt metal particles in these SiO 2-Pt/Cs seemed to be covered with thin silica layers .

Effect of Cement Replacement by Silica Fume and Fly Ash

The replacement level of silica fume is generally low at about 10%. When SF is used in concrete mix, its introduction affects the physical arrangement of the system, particularly near the aggregate surface where porosity exists. Silica fume starts reacting at the early stage of hydration process. The pozzolanic action of silica fume reduces
