Tunable and stable localized surface plasmon resonance in SrMoO4 for enhanced visible light driven nitrogen reduction

Photocatalytic nitrogen reduction for the green synthesis of ammonia at ambient conditions has been slowed by narrow light harvesting range, low activity and high charge recombination photocatalysts. Plasmonic semiconducting nanomaterials are becoming promising candidates photofixation because broad absorption spectrum, rich defects hot carriers. In present study, plasmonic SrMoO4 is developed regulating concentration oxygen vacancies that accompanied in process from Mo6+ to Mo5+. The stable tunable localized surface plasmon resonance (LSPR) visible near infrared range makes wide bandgap utilize solar energy more efficiently. Energetic electrons both intrinsic band excitation LSPR enable dinitrogen molecules thermodynamically ultrapure water ammonia. This work provides a unique clue design efficient photocatalysts fixation.
