Plasma-Liquid Interactions at Atmospheric Pressure for Nanomaterials Synthesis and Surface Engineering

Plasma‐induced non‐equilibrium liquid chemistry (PiLC) offers enhanced opportunities over solution chemistry for developing new nanomaterials and tailoring their functional properties. Recent advances in the design and scientific understanding of microplasma devices operating at atmospheric pressure offer simple and effective routes to non‐equilibrium chemistry for both scientific study and future nanomanufacturing. This paper presents a short review of our recent work on atmospheric pressure plasma–liquid interactions used in the fabrication and functionalization of nanoparticles. A brief discussion of possible electron‐liquid reactions highlights outstanding scientific and engineering questions. Atmospheric pressure plasmas that interact with liquids exhibit interesting phenomena that induce chemical reactions in a wide range of solutions. Plasma‐induced non‐equilibrium liquid chemistry offers new exciting avenues for the activation of chemical reactions in solution with interesting implications for traditional wet chemistry. Here opportunities for nanomaterial synthesis and surface engineering are highlighted.
