Direct and Sustainable Ammonia Synthesis from Air and Water with Sulfur-Deficient MoS₂ Piezocatalysts.

ABSTRACT: Eco-friendly ammonia (NH₃) production is critical for advancing sustainable agriculture and industry. This study introduces a sustainable, cleaner approach using MoS₂ nanoflowers (NFs) to synthesize NH₃ directly from water and air without the need for sacrificial agents. The advanced design leverages double sulfur vacancies (V2s) in MoS₂ NFs (V2s-MoS₂ NFs) and their piezoelectric properties, achieving a noteworthy production efficiency of 8374.8 ± 140.1 μmol L^-1 g^-1 h^-1 (absolute production rate of 0.84 ± 0.01 μmol h^-1). This outperforms most existing photocatalysts and piezocatalysts and rivals advanced electrocatalysts. The catalyst demonstrated exceptional stability, producing 36.55 mmol L
