Recent Progress on Rational Design of Catalysts for Fermentative Hydrogen Production

The increasingly severe energy crisis has strengthened the determination todevelop environmentally friendly energy. And hydrogen has emerged as a candi-date for clean energy. Among many hydrogen generation methods, biohydrogenstands out due to its environmental sustainability, simple operating environ-ment, and cost advantages. This review focuses on the rational design of catalystsfor fermentative hydrogen production. The principles of microbial dark fermen-tation and photo-fermentation are elucidated exhaustively. Various strategiesto increase the efficiency of fermentative hydrogen production are summa-rized, and some recent representative works from microbial dark fermentationand photo-fermentation are described. Meanwhile, perspectives and discussionson the rational design of catalysts for fermentative hydrogen production areprovided.
