Tungsten Nitride/Tungsten Oxide Nanosheets for Enhanced Oxynitride Intermediate Adsorption and Hydrogenation in Nitrate Electroreduction to Ammonia.

Electrochemical NO reduction reaction (NORR) is a promising technique for green NH synthesis. Tungsten oxide (WO) has been regarded as an effective electrocatalyst for electrochemical NH synthesis. However, the weak adsorption and the sluggish hydrogenation of oxynitride intermediates (NO, e.

Self-Reconstruction of Highly Degraded LiNi Co Mn O toward Stable Single-Crystalline Cathode.

The ever-growing demand for resources sustainability has promoted the recycle of spent lithium-ion batteries to a strategic position. Direct recycle outperforms either hydrometallurgical or pyrometallurgical approaches due to the high added value and facile treatment processes. However, the traditional direct recycling technologies are only applicable for Ni-poor/middle cathodes.

A Universal Molten Salt Method for Direct Upcycling of Spent Ni-rich Cathode towards Single-crystalline Li-rich Cathode.

With ever-increasing pursuit for high-value output in recycling spent lithium-ion batteries (LIBs), traditional recycling methods of cathodes tend to be obsolete because of the complicated procedures. Herein, we first upcycle spent polycrystal LiNi Co Al O (S-NCA) to high value-added single-crystalline and Li-rich cathode materials through a simple but feasible LiOH-Na SO eutectic molten salt strategy. The in situ X-ray diffraction technique and a series of paratactic experiments record the evolution process of upcycling and prove that excessive Li occupies the transition metal (TM) layers.

Synthesis of a Hexagonal Phase ZnS Photocatalyst for High CO Selectivity in CO Reduction Reactions.

ZnS materials exhibit very negative potential of the conduction band, which is promising in photocatalytic reduction reactions. Unfortunately, previously reported ZnS materials for photocatalysis are mainly in the cubic phase, which produce high activity for H evolutions and low activity toward CO reductions. Herein, a hexagonal phase ZnS photocatalyst is fabricated for highly efficient CO reduction reactions.
