A predictive method for efficient catalysts of the ORR reaction in hydrogen fuel cells.

  • Comments off

A key technological obstacle to the widespread adoption of proton exchange membrane fuel cells is the development of highly active and durable platinum-based catalysts to accelerate the slow oxygen reduction reaction (ORR). A team of CNR researchers from the Institute of Chemistry of Organometallic Compounds (CNR-ICCOM) and the Institute for Physical Chemistry Processes (CNR-IPCF), in […]

Hydrogen from Biomass

  • Comments off

The price of hydrogen produced with sustainable alternative processes, such as electrolysis and water splitting using sunlight, still makes these technologies uncompetitive from an economic point of view. In the context of the European Union Green Deal and the National Recovery and Resilience Plan (PNRR), which promote a sustainable energy transition, new technologies to produce […]

A stable ruthenium-hydride molecular complex promotes the sustainable production of green hydrogen from water electrolysis.

  • Comments off

Researchers from the Institute of Chemistry of Organometallic Compounds (ICCOM) of the National Research Council (CNR) have studied the production of green hydrogen from water in the laboratories of Sesto Fiorentino (FI), discovering that this can be promoted by a dinuclear organometallic complex of ruthenium in a polymer membrane electrolytic cell (PEM). The study was […]

A cheaper and cleaner way to make hydrogen peroxide

  • Comments off

Researchers at CNR-ICCOM and CNR-IMEM, in collaboration with the University of Trieste,  have developed an electrochemical catalyst for the more sustainable production of hydrogen peroxide, starting from a carbon nanomaterial. The method also solves the safety problems posed by one of the processes developed in recent years for the synthesis of H2O2, which uses hydrogen […]

Jagged Platinum nanowires achieve record mass activity and cost reduction for hydrogen fuel cells

  • Comments off

Shaping platinum into ultrafine jagged nanowires and using it as a catalyst in hydrogen fuel cells would dramatically increase efficiency, lower cost. An international team including a CNR-ICCOM researcher develops a method that allows a 50-fold reduction in the amount of platinum. Jagged platinum nanowires are obtained by removing nickel from Pt-Ni regular alloy nanowires. […]
