As primary air pollutants from fossil fuel combustion, the excess emission of nitric oxides (NOx) results in a series atmospheric environmental issues. Although selective catalytic reduction technology has been confirmed to be effective for NOx removal, green purification and value-added conversion under ambient conditions are still facing great challenges, especially nitrogen resource recovery. To address that, photo-/electrocatalysis offers sustainable routes efficient upcycling temperature pressure, which received considerable attention scientific communities.

Photocatalysis offers a promising avenue for the efficient removal of nitrate compounds from water by harnessing solar energy and transforming them to ammonia. The constraints, such as rapid charge carrier recombination comparatively low selectivity, however, hinder widespread application technology. In this study, an inexpensive bimetal sulfide (NiCo2S4, NCS) is anchored over phosphorus (P)-doped g-C3N4 (PCN) sheets. fabricated NCS-PCN heterojunction tested photocatalytic nitrate-reduction activity. Notably, dose composite with 30% (w/w) NCS shows optimal reduction, achieving 99% in 4 h, ammonia selectivity increasing ∼56 96%, compared PCN alone under identical conditions. photocatalyst also remarkable stability, experiencing marginal decrease less than 1% activity after 5 reaction-regeneration cycles. isotope labeling test using nuclear magnetic resonance spectroscopy confirms that salt supplied feedstock nitrogen source formed during photoreduction. observed enhanced activity, supported radical scavenging tests, electronic paramagnetic measurements, X-ray photoelectron spectroscopy, situ diffuse reflectance infrared Fourier transform spectroscopic analyses, provides evidence S-scheme-mediated transfer mechanism heterojunction. This study not only contributes valuable insights into light-harvesting but paves way sustainable processes on large scale.
