“…The NSGA-II was also proved to be an efficient method to optimize the toluene decomposition process in the PPC system. Jiang et al [128] found that the RSM is an efficient method to model the toluene degradation process and optimize the operation parameters (pulsed power, GHSV, RH, and oxygen content) in the PPC system over CoO x -CeO 2 catalyst. They proposed that the GHSV plays a dominant role in energy yield, whereas the pulsed power has a more pronounced effect on CO x selectivity.…”

The combination of non-thermal plasma (NTP) and catalyst characterized by high energy efficiency, enhanced volatile organic compounds (VOCs) removal efficiency, high product selectivity, and low production of unwanted and/or toxic by-products possesses a great promise for the abatement of VOCs. This work reviews the state of knowledge regarding Mn-based catalysts for VOCs abatement in the post-plasma-catalytic (PPC) system. First, the development and the performance of different Mn-based catalysts such as pure manganese oxide, mixed manganese oxide-based catalysts, and supported Mn-based catalysts in terms of VOCs abatement and O 3 decomposition are summarized. Then, the mechanism of the VOCs decomposition in the NTP and PPC system is discussed. Finally, the modeling and simulation of VOCs abatement in the NTP and PPC system are overviewed. This review aims at providing a reference guide for the development and optimization of VOCs abatement in the PPC system using Mn-based catalysts.

Tailored Catalytic Nanoframes from Metal–Organic Frameworks by Anisotropic Surface Modification and Etching for the Hydrogen Evolution Reaction

et al. 2021

A facile anisotropic surface modification and etching strategy is presented for the synthesis of hollow structured ZIF‐67 nanoframes. The strategy uses structural and compositional distinctions between each crystallographic facet of truncated rhombic dodecahedrons ZIF‐67 (tZIF‐67 RDs) and the moderate coordinating and etching effects of cyanuric acid (CA). The CA can anisotropically modify and protect the {110} facets from etching, causing the six {100} facets be selectively etched via an inside‐out manner, and finally forming the hollow nanoframes. The surface‐modified hollow tZIF‐67 RDs can be facet‐selectively etched by metal salts in an outside‐in manner to give metal‐doped tZIF‐67 nanoframes. After calcination, the metal‐tZIF‐67 hybrids are converted into metal‐Co alloy/C composite catalysts with hollow nanoframed structures. The PtCo/C catalyst with only 5.9 wt % Pt exhibits high catalytic activities and stabilities in the hydrogen evolution reaction (HER) in acidic solutions.

“…Nonthermal plasmas (NTPs) are characterized by the presence of electrons, ions, radicals, excited atoms, and molecules under ambient conditions [7]. In plasma, the energy of electrons can reach 1-20 eV [8], being able to produce clusters of active species such as excited atoms, positive or negative ions, and radicals via the collision between gas molecules and energized electrons [9]. ese active species, for instance, reactive nitrogen species (RNS) and reactive oxygen species (ROS), can destroy cell structures including cell membranes, proteins, and nucleic acids, leading to the inactivation or death of microorganisms [10,11].…”

Atmospheric pressure plasma jet (APPJ) is a promising technique for the sterilization of pathogenic microorganisms in an ambient environment. In this work, a helium-APPJ was generated by double dielectric barrier discharge and applied to the sterilization of model microorganism in air and water. Discharge characteristics (including waveform and frequency of applied voltage), jet properties (such as feed gas flow rate, jet length, thermal effect, and optic emission spectra), and sterilization performance (in terms of clear/sterilized area, size of plaques, and sterilization efficiency) were investigated. Homogeneous helium plasma jet was generated in an energy-efficient way (18 kHz, 6 kV, 0.08 W) with a 19 mm jet and limited heating. The He-APPJ achieved good sterilization performances within very short treatment time (as short as 30 s). For surface sterilization, the area of clear zone and size of the plaque were 1809 mm2 and 48 mm, respectively, within 5 min treatment. For water sterilization, 99.8% sterilization efficiency was achieved within 5 min treatment. The optic emission spectra suggest that active species such as excited molecules, ions, and radicals were produced in the He-APPJ. The as-produced active species played important roles in the sterilization process.
