摘要: Heterogeneous catalysis performed in wall-coated reactors and electrocatalysis require homogeneous catalytic coatings with high surface area good accessibility of the active sites. Conventional coating methods necessitate use binder components that often block pores sites, which limits efficiency, utilization expensive metals. We report an approach for direct binder-free synthesis chemically, mechanically, thermally stable based on ordered mesoporous carbon films employed as catalyst support. The relies codeposition a structure-directing agent small clusters polymeric precursors along ionic metal species substrate. A sequence thermal treatments converts polymer into partly graphitized carbon, decomposes agent, precursor highly nanoparticles. Syntheses applications are exemplarily demonstrated palladiu...
