Abstract Large amounts of CO 2 have disrupted the natural carbon cycle. reduction reaction (CO RR) is an effective strategy to reduce high concentration . Currently, design cathode catalyst widespread promote RR. However, effect electrolyte on catalytic fuzzy. Hence, silver nanoparticles (Ag NPs) synthesized conveniently by a one-pot method was used study effects different electrolytes activity and selectivity in 0.1 M NaHCO 3 , KHCO KCl as were applied into Efficient RR performances are exposed three electrolytes. The results show that optimal choice with maximum over 80%, which better than many reports. Meanwhile, enhances but poisons active site weaken selectivity. This research affords direction for acquainting oneself exploit new energy.

Plasmonic Hafnium Nitride Nanoparticle‐Decorated Graphitic Carbon Nitride for Plasmon‐Enhanced Photocatalytic Dye Degradation

Nano Select, Journal Year: 2025, Volume and Issue: unknown

Published: March 15, 2025

ABSTRACT Photocatalytic dye degradation under visible light irradiation is restricted by the poor absorption and rapid recombination of photogenerated electron‐hole pairs in traditional materials, such as graphitic carbon nitride (g‐CN), hindering their practical applications. In this study, a plasmonic hafnium (HfN)‐decorated nanocomposite (HfN@g‐CN) was developed incorporating HfN nanoparticles (NPs) into g‐CN. The incorporation NPs enhanced facilitated efficient electron transfer. Moreover, SEM TEM analyses confirmed uniform distribution on g‐CN surface. photocatalytic activity tested during Rhodamine B (Rh B) upon achieved rate 3.7 × 10⁻ 3 g·h⁻¹·g⁻¹ catalyst, which times higher than that for pure These findings highlight potential HfN@g‐CN stable photocatalysts applications environmental remediation solar‐driven chemical processes.
