Summary: Electrocatalytic reduction of nitrogen into NH3 is currently of paramount importance due to its potential as a clean energy source and primary precursor for nitrogenous compounds. The conventional method for NH3 synthesis, Haber-Bosch process, is energy inefficient, while electrochemical synthesis can overcome this hurdle. In this review, Pd-based electrocatalysts for nitrogen reduction reaction (NRR) are critically reviewed and summarized, along with discussions on possible mechanisms, strategies to suppress Hydrogen Evolution Reaction (HER) for enhanced NRR, and the role of electrolyte pH on electrocatalyst's efficiency. The classification and systematic discussion of previously reported Pd catalysts in the context of NH3 generation and faradaic efficiency are provided, highlighting the potential for further improvement in electrocatalyst design.

Summary: Under visible light illumination, the p-n WO3/SnSe2 heterojunction significantly activates the oxygen evolution reaction (OER) catalysis of CoFe-layered double hydroxide (CF)/carbon nanotubes (CNTs), achieving a low overpotential of 224 mV at 10 mA cm(-2) and a small Tafel slope of 47 mV dec(-1), surpassing RuO2 and most previously reported transition metal-based OER catalysts. The p-n WS heterojunction exhibits strong light absorption and produces photogenerated carriers, with the photogenerated holes trapped by CF to suppress charge recombination and facilitate charge transfer, accelerating OER kinetics and enhancing the OER activity. This study highlights the possibility of using heterojunctions to activate OER catalysis and advances the design of energy-efficient catalysts for water oxidation systems using solar energy.

Summary: With the development of industrial and agricultural activities, the excessive production of nitrate has become a serious environmental and public health concern. Among various nitrate treatment techniques, electrochemical nitrate reduction reaction (eNRR) has gained significant attention due to its mild conditions and pollution-free nature. However, understanding the eNRR mechanism requires the use of in situ and operando techniques to study the reaction process at a time-resolved and atomic level.

Summary: In this study, chlorosalicylaldehyde-functionalized carbon dots (CDs) with solid-state fluorescence were prepared via molecular self-assembly. The position of chlorine on the aromatic core of chlorosalicylaldehyde affected the coplanarity and degree of conjugation of the CDs, thereby adjusting their emission wavelengths. The self-assembly process showed distinct isomeric effects, resulting in different morphologies. The multicolor luminescence of the CDs makes them potential candidates for light-emitting diodes, fluorescent films, and fingerprint detection.
