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 removal and conversion of nitrate (NO3–) from wastewater has become an important environmental health topic. NO3– can be reduced to nontoxic nitrogen (N2) for remediation or ammonia (NH3) recovery, in which the tailoring selectivity is greatly challenging. Here, by construction CuOx@TiO2 photocatalyst, efficiency enhanced ∼100%. Moreover, precise regulation NH3 (∼100%) N2 (92.67%) accomplished synergy cooperative redox reactions. It identified that photoreduction determined combination different oxidative key roles intermediates reactive radicals are revealed comprehensive situ characterizations, providing direct evidence regulated photoreduction. Different active produced interaction reactants light-generated holes. Specifically, introduction CH3CHO as reactant results generation formate radicals, drives selective reduction into its remediation. alkyl contributed (CH2OH)2 oxidation, facilitate deep upcycling. This work provides a technological basis radical-directed purification resource recovery.
