TA10 Titanium Alloy in HCl Solution: W‐Influenced Corrosion and Passivation Film Evolution
Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT This work investigated the evolution of passive films of Ti–0.3Mo–0.8Ni (TMN) in 5 mol L−1 HCl and studied the influence of W on the anti‐corrosion properties of TMN. The intermittent electrochemical impedance spectroscopy test results showed that when TMN entered 5 mol L−1 HCl solution, the stability of the passive film first became stronger ...

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Electrosynthesis of hydrogen peroxide (H2O2) via the two‐electron oxygen reduction reaction (2e−ORR) offers a sustainable and decentralized alternative to the anthraquinone process. However, conventional solo‐active‐site catalysts are intrinsically limited by scaling relationships, imposing a trade‐off between activity and selectivity.
