Regulating surface oxygen species on copper (I) oxides via plasma treatment for effective reduction of nitrate to ammonia
TL;DR: Wang et al. as mentioned in this paper demonstrate that tuning the oxygen chemical environment via Ar plasma treatment is an effective approach to improve the NO3-RR activity of Cu2O. They find that plasma treatment can effectively promote the formation of oxygen vacancies and hydroxyl groups on CU2O surface, thus leading to improved ammonia selectivity.

Understanding the Z-scheme heterojunction of BiVO4/PANI for photoelectrochemical nitrogen reduction.
TL;DR: Based on the idea that a heterojunction can significantly promote photoelectrochemical (PEC) efficiency, BiVO4/PANI (polyaniline), as a Z-scheme heterjunction, was designed in this article, which achieved a desirable NH3 yield rate (rNH3 = 0.93 μg h−1 cm−2) and faradaic efficiency (FE = 26.43%).

Fabrication of Zn-MOF decorated BiVO4 photoanode for water splitting
TL;DR: In this article , Zn-MOF with large surface area and abundant exposed active sites was decorated on BiVO4 photoanode, exhibiting boosted PEC activity. But, the PEC performance was still seriously hindered due to low carrier transmission efficiency and slow water oxidation kinetics.
