Piezocatalytic nitrate reduction to ammonia in seawater.

ABSTRACT: The renewable-energy-driven conversion of nitrate in seawater into ammonia ions (NH₄ ⁺) is a promising strategy for concurrent marine environmental remediation and sustainable chemical production. Herein, a seawater piezocatalytic nitrate reduction reaction (NitRR) is demonstrated for efficient NH₄ ⁺ production by employing MnPS₃ nanosheets (NSs) as a new type of piezocatalyst. It is shown that the Mn and P dual sites promote the adsorption and activation of NO₃ ^- ions via an asymmetric side-on mode. Moreover, the lattice strain of MnPS₃ NSs induced by the external mechanical vibration further weakens the N-O bond. With the additional contribution of the active hydrogen supplied by the S sites, the MnPS
