Ambient Ammonia Synthesis via Electrochemical Reduction of Nitrate Enabled by NiCo2O4 Nanowire Array

Qian Liu et al.

Summary: NiCo2O4 nanowire array on carbon cloth (NiCo2O4/CC) is proposed as a highly active electrocatalyst for ambient nitrate (NO3-) reduction to ammonia (NH3). It achieves a high Faradic efficiency of 99.0% and a large NH3 yield up to 973.2 mu mol h(-1) cm(-2). The superior catalytic activity comes from its half-metal feature and optimized adsorption energy due to the existence of Ni in the crystal structure.

Greatly Facilitated Two-Electron Electroreduction of Oxygen into Hydrogen Peroxide over TiO2 by Mn Doping

Quanying Chen et al.

Summary: In this study, Mn-doped TiO2 was used as an efficient electrocatalyst for highly selective H2O2 synthesis, showing low onset potential and high H2O2 selectivity. Density functional theory calculations revealed that Mn dopant improved the electrical conductivity and reduced the activation energy, leading to a highly efficient H2O2 production process. The significantly boosted catalytic performance can be attributed to the lattice distortion of Mn-doped TiO2 with a large amount of oxygen vacancies and Ti3+.

Changhong Wang et al.

Summary: In this study, Ni nanosheet arrays with Ni vacancies exhibited outstanding electrocatalytic performances towards selective nitrite reduction to ammonia and semi-dehydrogenation of tetrahydroisoquinolines. The decrease in electronic cloud density induced by the Ni vacancies improved NO2- adsorption and NH3 desorption, leading to high performance in nitrite-to-ammonia conversion. Additionally, a bifunctional two-electrode electrolyzer was constructed for simultaneous production of ammonia and dihydroisoquinoline with robust stability and high selectivity.
