Abstract: Direct decomposition of hydrogen sulfide is an effective way not only to treat the waste gas in coal,petroleum,natural gas and mineral processing industries for solving the environmental pollution problems but also to produce sulfur and a clean energy,hydrogen. In this paper,the research progress of hydrogen and sulfur produced from direct decomposition of hydrogen sulfide including themolysis(directly high-temperature thermolysis,catalytic thermolysis and superadiabatic thermolysis),electrochemical technology,photocatalytic decomposition and plasma technology are reviewed. Fundamental principle and themodynamic basis of methods involved are briefly introduced. Then, a detailed description of research status focused on research methods,technique feature,reaction performance,advantage and disadvantage,and potential breakthrough point,etc. is given. The future development trend is prospected at the end of this review as well. A prospect is put forward that continuously exploring and developting new technologies such as combining membrane technology,catalytic technology and plasma technology would be the future trend in the field of hydrogen production from H2S decomposition.
