Developing sustainable FeTi alloys for hydrogen storage by recycling

Abstract Intermetallic alloys such as FeTi have attracted ever-growing attention a safe and efficient hydrogen storage medium. However, the utilization of high-purity metals for synthesis materials poses considerable concerns over environmental sustainability their large-scale production. Here, we report an approach synthesizing from industrial scraps iron (steels C45 316 L) titanium (Ti alloy Grade 2) to reduce carbon footprint associated with synthesis, without compromising properties. At 50 °C pressure 0 100 bar, obtained by using C45-Ti 2 316L-Ti can absorb maximum amount 1.61 wt.% 1.50 wt.%, respectively. Moreover, depending on type steel utilized, thermodynamic properties be modified. Our findings pave pathway developing high-performance, environmentally-sustainable purposes metal wastes.
