Recently, electrocatalytic nitrogen fixation into ammonia has provoked wide attention due to its capability to be performed under mild condition, with the electricity as the only power input. Nevertheless, the conventional metal-based electrocatalysts normally suffers from their difficulty in balancing the competitive reactions of nitrogen adsorption/activation and hydrogen generation, hampering the ammonia production efficiency. Lately, metal-free electrocatalysts have turned up as a promising candidate for such an approach due to their highly controllable surface-structure and relatively sluggish hydrogen generation activity. In this review, we summarize recent progress in electrocatalytic nitrogen reduction reaction using metal-free electrocatalysts, with the particular emphasis on their electronic structure and microstructure modulations for ameliorating N2 adsorption/activation and electron transfer.

Numerous efforts have been devoted on physical blocking and chemical adsorption for inhibiting of lithium polysulfides (LiPSs), which are not efficient enough for high sulfur-loading and ultra-long cycling life. In recent years, the concept of catalysis is proposed in LSBs, which can not only alleviate the shuttle effect, but also accelerate the redox kinetics and prolong the lifespan. Herein, we will highlight the catalytic effects in the cathode of LSBs comprehensively. Firstly, we introduce the electrochemistry mechanism of LSBs.
