Electroreduction of nitrite (NO2−) to valuable ammonia (NH3) offers a sustainable and green approach for NH3 synthesis. Here, a Cu3P@TiO2 heterostructure is rationally constructed as an active catalyst for selective NO2−‐to‐NH3 electroreduction, with rich nanosized Cu3P anchored on a TiO2 nanoribbon array on Ti plate (Cu3P@TiO2/TP). When performed in the 0.1 m NaOH with 0.1 m NaNO2, the Cu3P@TiO2/TP...
Synthesis of green ammonia (NH3) via electrolysis of nitric oxide (NO) is extraordinarily sustainable, but multielectron/proton‐involved hydrogenation steps as well as low concentrations of NO can lead to poor activities and selectivities of electrocatalysts. Herein, it is reported that oxygen‐defective TiO2 nanoarray supported on Ti plate (TiO2−x/TP) behaves as an efficient catalyst for NO reduction...
Electrochemical nitrate (NO3−) reduction reaction (NO3−RR) is a potential sustainable route for large‐scale ambient ammonia (NH3) synthesis and regulating the nitrogen cycle. However, as this reaction involves multi‐electron transfer steps, it urgently needs efficient electrocatalysts on promoting NH3 selectivity. Herein, a rational design of Co nanoparticles anchored on TiO2 nanobelt array on titanium...
