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. In this review, recent advances critically summarized. The target products reaction mechanisms systems, together with responsible active sites, discussed, respectively. Then, realistic practicability is proposed, including strict performance evaluation criteria application by photo-/electrocatalysis. Finally, current challenges future opportunities proposed terms catalyst design, enhancement, mechanism understanding, practical conditions, product separation techniques.

The chemical composition of indoor air is strongly driven by the and properties surfaces. At Chemical Assessments Surfaces Air (CASA) campaign, we performed controlled additions ammonia (reaching up to 297 ppb 662 ppb) investigate impacts changing surface basicity on fate gaseous particulate acids bases in an unoccupied house. In response injections, nitrogen-containing compounds (C2–7H3–11N1O0–3) were emitted from surfaces gas phase with signals increasing 101% 104% compared their prior addition. same time, oxygen-containing (C1–7H2–6O2–3) removed partitioning. Indoor pH aerosol likely increased during these injections relative baseline conditions. We estimate be nearly 5 range 2 4 this experiment. each injection, observed ammonium nitrate concentrations increase due gas-particle partitioning nitric acid. This gas-particle-surface exchange showed strong dependence humidity; evaporation was more pronounced at lower humidity when surface-associated water volume reduced, while gas-to-particle inorganic species greater presence liquid higher humidity. From cooking experiments, which represent realistic sources environment but emit 10 times less than introduced house via pure injection predict that may still important basic gases air.
