Mesoporous Pt–Co oxygen reduction reaction (ORR) catalysts for low temperature proton exchange membrane fuel cell synthesized by alternating sputtering

In-situ electrochemical atomic force microscopy study of aging of magnetron sputtered Pt-Co nanoalloy thin films during accelerated degradation test

“…So far, a large number of studies reported Pt-Co alloy nanoparticles prepared by wet techniques. Although the number of publications devoted to PtCo materials obtained by physical deposition methods is relatively small [14][15][16][17], it has been proved that a catalyst prepared in such a way is also promising for ORR. In our previous studies we have showed that simultaneous magnetron sputtering of Pt and Co leads to the formation of Pt-Co alloy catalyst film [18,19].…”

Tetrakis(trimethylsilyloxy)silane for nanostructured SiO2-like films deposited by PECVD at atmospheric pressure

“…In particular, a stability against chemical or mechanical impact is desirable for coatings in a wide range of morphologies. For instance, permeation barriers rely on compact pin-hole free coatings [6] whereas surfaces for heterogeneous catalysis require hierarchically nano-structured films with large surface area and their catalysts centered in chemically stable matrices [7,8]. The importance of hybrid materials production from molecular precursors leads to investigation of organosilicates from complex precursors.…”

Nanostructuring Noble Metals as Unsupported Electrocatalysts for Polymer Electrolyte Fuel Cells

“…[114] The latter were mostly removed through dissolution during cell conditioning, leaving behind a mesoporous PtCo CL with improved mass-normalized performance at high current densities under H 2 /air operation with respect to pure Pt CLs prepared by the same process. The macroporous Pt CLs with inverse opal structure on a GDL (as shown in Figure 6f) exhibits an ECSA amounting to 24 m 2 g Pt −1…”
