Nitrite (NO2−) and hydrazine (N2H4) are common N‐pollutants in groundwater. The electrochemical method can realize the treatment of N‐pollutants and the synthesis of energy substance ammonia (NH3). Designing and synthesizing efficient electrocatalysts is of great significance. Herein, ultrathin Co0.5NiS nanosheets attached on nickel foam (Co0.5NiS‐NSs/NF) are synthesized via cyanogel‐NaBH4 hydrolysis...
Ammonia (NH3) is an essential chemical for agricultural production and a promising next‐generation hydrogen‐rich fuel. The electrocatalytic nitrate (NO3−) reduction reaction (NO3RR) to NH3 provides a sustainable and low‐energy method to replace industrial NH3 synthesis. However, the NO3− to NH3 conversion is limited by the complex eight‐electron and nine‐proton reduction processes, thus it is highly...
Nitrate is a reasonable alternative instead of nitrogen for ammonia production due to the low bond energy, large water‐solubility, and high chemical polarity for good absorption. Nitrate electroreduction reaction (NO3RR) is an effective and green strategy for both nitrate treatment and ammonia production. As an electrochemical reaction, the NO3RR requires an efficient electrocatalyst for achieving...
