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 […]

The discovery of a new synthesis of phosphine (PH3) and the missing compound (PH3)2H2

  • Comments off

A recent study, published on Nature Communications, describes the discovery of a new synthesis of phosphine (PH3) starting from the elements under conditions of high pressure and high temperature in the absence of catalysts. The study, carried out by a team of researchers of the Institute of Chemistry of OrganoMetallic Compounds of the National Research […]

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. […]

Production of Energy from High Performance, Platinum-Free Fuel Cells

  • Comments off

Thanks to innovative anode electrocatalysts based on nanostructured palladium, the first entirely platinum-free fuel cells have been created that release a power density greater than 500 mW cm-2. Their use could revive hydrogen technology for cars and portable energy generators with “zero emissions” of pollutants. The research was coordinated by ICCOM-Cnr of Florence. A fuel […]

Phosphorene: a New Platform for Multifunctional Materials

  • Comments off

Phosphorene is a 2D material consisting of a single ordered layer of phosphorus atoms and can be prepared by exfoliation of black phosphorus, one of the crystalline forms of elemental phosphorus. 2D materials have attracted a great deal of interest for some years for their potential use in different fields. Among these, the best known, […]
