Editing Iron (section)

===Catalysts and reagents===
Because Fe is inexpensive and nontoxic, much effort has been devoted to the development of Fe-based catalysts and [[reagent]]s.  Iron is however less common as a catalyst in commercial processes than more expensive metals.<ref>{{cite journal |doi=10.1021/acscentsci.6b00272|title=Iron Catalysis in Organic Synthesis: A Critical Assessment of What It Takes to Make This Base Metal a Multitasking Champion |year=2016 |last1=Fürstner |first1=Alois |journal=ACS Central Science |volume=2 |issue=11 |pages=778–789 |pmid=27981231 |pmc=5140022 }}</ref>  In biology, Fe-containing enzymes are pervasive.<ref>{{cite journal |doi=10.1126/science.abc3183|title=Using nature's blueprint to expand catalysis with Earth-abundant metals |year=2020 |last1=Bullock |first1=R.

Iron catalysts are traditionally used in the [[Haber–Bosch process]] for the production of ammonia and the [[Fischer–Tropsch process]] for conversion of carbon monoxide to [[hydrocarbon]]s for fuels and lubricants.<ref>{{Cite book| title = Surface science: foundations of catalysis and nanoscience|first = Kurt W.|last = Kolasinski|isbn = 978-0-471-49244-3| publisher =John Wiley and Sons|date = 2002|chapter-url={{Google books|OA7L1l6oHAYC|page=PR15|keywords=|text=|plainurl=yes}}|chapter = Where are Heterogenous Reactions Important|pages = 15–16}}</ref> Powdered iron in an acidic medium is used in the [[Bechamp reduction]], the conversion of [[nitrobenzene]] to [[aniline]].<ref>{{Cite book| chapter-url={{Google books|BiywGdlot9kC|page=PA167|keywords=|text=|plainurl=yes}}|chapter = Nitrobenzene and Nitrotoluene |isbn = 978-0-8247-2481-8|publisher = CRC Press|date = 1989|first = John J.|last = McKetta|title = Encyclopedia of Chemical Processing and Design: Volume 31 – Natural Gas Liquids and Natural Gasoline to Offshore Process Piping: High Performance Alloys|pages = 166–67}}</ref>
