Synergy of Bi O and RuO Nanocatalysts for Low-Overpotential and Wide pH-Window Electrochemical Ammonia Synthesis.

Electrocatalytic nitrogen reduction reaction (NRR) under ambient conditions is still seriously impeded by the inferior NH yield and low Faradaic efficiency, especially at low overpotentials. Herein, we report the synthesis of nano-sized RuO and Bi O particles grown on functionalized exfoliated graphene (FEG) through in situ electrodeposition, denoted as RuO -Bi O /FEG. The prepared self-supporting RuO -Bi O /FEG hybrid with a Bi mass loading of 0.

Bismuth-Based Free-Standing Electrodes for Ambient-Condition Ammonia Production in Neutral Media.

Electrocatalytic nitrogen reduction reaction is a carbon-free and energy-saving strategy for efficient synthesis of ammonia under ambient conditions. Here, we report the synthesis of nanosized BiO particles grown on functionalized exfoliated graphene (BiO/FEG) via a facile electrochemical deposition method. The obtained free-standing BiO/FEG achieves a high Faradaic efficiency of 11.

Ultrathin 1T-MoS Nanoplates Induced by Quaternary Ammonium-Type Ionic Liquids on Polypyrrole/Graphene Oxide Nanosheets and Its Irreversible Crystal Phase Transition During Electrocatalytic Nitrogen Reduction.

Ultrathin nanoplates of metastable 1T-MoS have been successfully stabilized and uniformly distributed on the surface of -butyl triethyl ammonium bromide functionalized polypyrrole/graphene oxide (BTAB/PPy/GO) by a very simple hydrothermal method. BTAB as a typical kind of quaternary ammonium-type ionic liquids (ILs) played a crucial role in the formation of the obtained 1T-MoS/BTAB/PPy/GO. It was covalently linked with PPy/GO and arranged in a highly ordered order at the solid-liquid interface of PPy/GO and HO due to Coulombic interactions and other intermolecular interactions, which would induce and stabilize ultrathin 1T-MoS nanoplates by morphosynthesis.
