An improved palladium-based DMFCs cathode catalyst
, 2004 A novel carbon-supported palladium-rich Pd3Pt1/C catalyst prepared by a modified polyol process showed a better cell performance than Pt/C in direct methanol fuel cells, which may be attributed to palladium's inactivity to methanol electro-oxidation ...

Advanced Functional Materials, EarlyView.Sulfur fluoride exchange (SuFEx) is a powerful click platform, yet water‐compatible multifunctional linchpins remain elusive. Here, we report decagram‐scalable diazonium linchpins that enable rapid Pd‐catalyzed diversification and direct, catalyst‐free on‐DNA ligation in aqueous media.

Advanced Functional Materials, EarlyView.Sulfur‐doped graphitized carbon nanofibers act as adaptive catalyst–support platforms, enabling dynamic sulfur‐mediated reconstruction and strong metal–support interactions. This unique behavior enhances catalyst stability and controls reaction pathways, achieving highly selective urea oxidation (∼92% N2) coupled with efficient hydrogen evolution ...

Electronic Modifictions in Supported Palladium Catalysts
, 1994 XPS and IR spectroscopy indicate that the electron density of the supported metal clusters in Pd/LTL catalysts is a function of the support acidity/alkalinity. In addition, the neopentane and propane hydrogenolysis TOF's increase with increasing support acidity from alkaline to acidic.

Palladium-on-Charcoal Catalysts
Platinum Metals Review, 1961 The performance of charcoal-based catalysts cannot be described simply in terms of their mesh size and noble metal content, as many factors can cause wide variations in activity, selectivity and resistance to poisoning. It is possible, however, by close collaboration between catalyst manufacturer and user, and by suitable choice of base and production ...
