A review on hydrogen production from hydrogen sulphide by chemical and photochemical methods

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

“…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.…”

Energy‐Band‐Controlling Strategy to Construct Novel CdxIn1‐xS Solid Solution for Durable Visible Light Photocatalytic Hydrogen Sulfide Splitting

“…Annually, millions of tons (>4 × 10 7 t) hydrogen sulfide (H 2 S) are produced from the natural or anthropic processes such as oil‐refinery, natural‐gas extraction, and black sea, and so on, which is predicted to increase rapidly in the future. H 2 S is very harmful to the environment and human beings when the content of H 2 S is higher than the threshold limit of 10 ppm .…”

“…H 2 S is very harmful to the environment and human beings when the content of H 2 S is higher than the threshold limit of 10 ppm . On the other hand, H 2 S is also a potential resource if both sulfur (S) and hydrogen (H 2 ) can be recovered . Therefore, the resource utilization of H 2 S has attracted great attention.…”

“…Therefore, the resource utilization of H 2 S has attracted great attention. Up to now, several methods for converting H 2 S into H 2 and S have been proposed to realize the resource utilization of H 2 S, including thermal, thermochemical, electrochemical, and plasmochemical methods. However, these methods usually require extra energy and involve expensive equipment.…”
