Hydrogen from hydrogen sulfide: towards a more sustainable hydrogen economy

Molybdenum‐ and vanadium‐containing perovskite electrocatalysts for dissociation of H 2 S

“…Natural gas (mostly methane) and “product gas” obtained via biomass gasification, commonly used as SOFC fuels, often contain varying amounts of H 2 S, which generally lead to corrosion and passivation of electrodes …”

“…As the demand for clean energy is growing, hydrogen production from H 2 S offers an opportunity for eliminating a toxic substance that is available at vast amounts from industrial and natural sources . Various methods, including thermochemical, electrochemical, photochemical, and plasmochemical methods, have been investigated at different levels . Although thermal decomposition is the most developed approach, electrochemical methods, allowing operation at relatively low temperatures for producing hydrogen and/or electricity, are developing as well.…”

“…8,43,44 Natural gas (mostly methane) and "product gas" obtained via biomass gasification, commonly used as SOFC fuels, often contain varying amounts of H 2 S, which generally lead to corrosion and passivation of electrodes. 7 In the present work, Mo-and V-containing perovskite electrocatalysts with La and Sr have been synthesized and studied in terms of electrical conductivity, with the purpose of developing chemically and thermally stable sulfur-resistant, electrode materials eligible for operating at a wide range of temperatures in SOFC and CFCs (ceramic fuel cells).…”

Catalytic hydrolysis of alkaline sodium borohydride solution for hydrogen evolution in a micro‐scale fluidized bed reactor

“…Due to the shortage of fossil fuels and growing concerns about environmental issues, hydrogen, as a promising source of renewable energy, has attracted increasing attention from around the world 6‐9 . Nevertheless, the efficiency and safety of storage remain what restricts the widespread applications of hydrogen.…”
