Sustainable plasma-catalytic bubbles for hydrogen peroxide synthesis
Hydrogen peroxide (H2O2) is a green oxidant widely used in various fields, from water treatment to rocket propellant. In this study, an argon plasma-catalytic bubble process was designed to generate underwater plasma bubbles for efficient delivery of reactive species for H2O2 synthesis, using only water as a reactant and solar radiation as the renewable energy source.
Long-Chain Hydrocarbons from Nonthermal Plasma-Driven Biogas Upcycling
The burgeoning necessity to discover new methodologies for the synthesis of long-chain hydrocarbons and oxygenates, independent of traditional reliance on high-temperature, high-pressure, and fossil fuel-based carbon, is increasingly urgent. In this context, we introduce a nonthermal plasma-based strategy for the initiation and propagation of long-chain carbon growth from biogas constituents (CO2 and CH4). Utilizing a plasma reactor operating at atmospheric room temperature, our approach facilitates hydrocarbon chain growth up to C40 in the solid state (including oxygenated products), predominantly when CH4 exceeds CO2 in the feedstock.
Sustainable Ammonia Synthesis from Nitrogen and Water by One-Step Plasma Catalysis
Sustainable ammonia synthesis at ambient conditions that relies on renewable sources of energy and feedstocks is globally sought to replace the Haber–Bosch process. Here, using nitrogen and water as raw materials, a nonthermal plasma catalysis approach is demonstrated as an effective power-to-chemicals conversion strategy for ammonia production. By sustaining a highly reactive environment, successful plasma-catalytic production of NH3 was achieved from the dissociation of N2 and H2O under mild conditions.
