Hydrogen (H2) Recovery From Hydrogen Sulfide (H2S): Current Technologies, Challenges, and Future Outlook

Advanced Science, Volume 13, Issue 36, 29 June 2026.
ABSTRACT Hydrogen sulfide (H2S) can be transformed into hydrogen (H2) through several chemical and catalytic processes, offering a promising route for both waste treatment and clean H2 production. This colorless, flammable, and toxic gas is found abundantly in swamps, volcanoes, hot springs, sewages, other natural gas fields, and even in refineries and

The Effect of Permanent Magnet on Dielectric Barrier Discharge (DBD) and Ozone Production

Journal of Physics: Conference Series, 2020
Abstract This paper reports the experimental results on the characteristic of ozone generator induced by a magnetic field from permanent magnets (ring PMs or combination of ring PMs and neodymium PMs) and a solid dielectric (floor ceramic/tile). Three electrode configurations (Models I, II and III) with ring PMs installed above and below

Deactivation of yeast by dielectric barrier discharge

, 2009
Saccharomyces Cerevisiae (S. Cerevisiae) and Mrakia Frigida (M. Frigida) were deactivated using alternative current dielectric barrier discharge (DBD). The deactivation was done in argon and oxygen plasma under different discharge currents.

Tuning the Geometric and Electronic Structures in PtMn/SiO2 Catalysts via Oxygen Plasma Treatment for Enhanced Propane Dehydrogenation

Carbon and Hydrogen, Volume 28, Issue 2, Page 184-195, June 2026.
Oxygen plasma treatment promotes Pt dispersion, reducing the average Pt particle size of PtMn catalyst from 2.7 to 1.2 nm, and increases the electron cloud density of Pt. The optimized catalyst exhibits excellent mass‐normalized activity (171 molC3H8·gPt−1·h−1) and an ultralow deactivation rate constant, outperforming most reported Pt‐based catalysts ...
