Abstract Solar-powered electrochemical NH3 synthesis offers the benefits of sustainability and absence of CO2 emissions but suffers from a poor ...

The cracking of ammonia to hydrogen and nitrogen ... to optimise the energy requirement, a PGM-based catalyst is often used, typically ruthenium. LOHCs absorb and release hydrogen through chemical ...

they could increase the electron density of ruthenium and maximize the performance of the catalyst. The newly created catalyst recorded over seven times the ammonia synthesis performance compared ...

However, catalysts are necessary to facilitate this process. To date, noble metal oxides such as ruthenium dioxide and iridium dioxide are being used as benchmark catalysts. These metals ...
