Summary: Nitrogen-doped three-dimensional graphene (N-doped 3D-graphene) is a graphene derivative with great adsorption capacity, large specific surface area, high porosity, and optoelectronic properties. By growing N-doped 3D-graphene/Si heterojunctions on silicon substrates via plasma-assisted chemical vapor deposition (PACVD), surface-enhanced Raman scattering (SERS) substrates with promising applications are achieved. The incorporation of N atoms in 3D-graphene increases the electronic state density and enhances charge transfer, leading to improved optical and electric fields. The as-prepared SERS substrates based on N-doped 3D-graphene/Si heterojunctions demonstrate ultra-low detection for various molecules and show potential in low-concentration molecular detection and food safety.

Summary: In this study, the researchers developed an electrocatalyst for efficient ammonia synthesis under ambient conditions. By decorating vertical NiCo2O4 pillars with boron-doped carbon dots (BCDs), they achieved a near 100% Faradaic efficiency (FE) for nitrate reduction to ammonia. The remarkable performance was attributed to the abundance of Lewis acid sites provided by the BCDs, which facilitated the adsorption of nitrate ions and suppressed the competitive hydrogen evolution reaction (HER).
