This work reports an innovative method to directly synthesize M<jats:sub>2<\/jats:sub>S NCs through alcohol\u2010mediated reactions between alkali metals and hydrogen sulfide (H<jats:sub>2<\/jats:sub>S). In the first step, the alkali metal is complexed with alcohol in solution, forming metal alkoxide (ROM) and releasing hydrogen (H<jats:sub>2<\/jats:sub>). Next, H<jats:sub>2<\/jats:sub>S is bubbled through the ROM solution, where both chemicals are completely consumed to produce phase\u2010pure M<jats:sub>2<\/jats:sub>S NC precipitates and regenerate alcohol that can be recycled. The M<jats:sub>2<\/jats:sub>S NCs morphology may be tuned through the choice of the alcohol and solvent. Both synthetic steps are thermodynamically favorable (\u0394<jats:italic>G<\/jats:italic><jats:sub>m<\/jats:sub><jats:sup>o<\/jats:sup>&lt;\u2212100\u2005kJ\u2009mol<jats:sup>\u22121<\/jats:sup>), proceeding rapidly to completion at ambient temperature with almost 100\u2009% atom efficiency.

This scalable approach provides an energy\u2010efficient and environmentally benign solution to the production of nanostructured materials required in emerging battery technologies.<\/jats:p>","DOI":"10.1002\/cssc.201700532","type":"journal-article","created":{"date-parts":[[2017,5,16]],"date-time":"2017-05-16T12:33:38Z","timestamp":1494938018000},"page":"2904-2913","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Reactive Precipitation of Anhydrous Alkali Sulfide Nanocrystals with Concomitant Abatement of Hydrogen Sulfide and Cogeneration of Hydrogen"],"prefix":"10.1002","volume":"10","author":[{"given":"Xuemin","family":"Li","sequence":"first","affiliation":[{"name":"Department of Chemistry Colorado School of Mines  1012 14th Street Golden CO 80401 USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yangzhi","family":"Zhao","sequence":"additional","affiliation":[{"name":"Department of Chemistry Colorado School of Mines  1012 14th Street Golden CO 80401 USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alice","family":"Brennan","sequence":"additional","affiliation":[{"name":"Department of Chemical and Biological Engineering Colorado School of Mines  1613 Illinois Street Golden CO 80401 USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miranda","family":"McCeig","sequence":"additional","affiliation":[{"name":"Department of Chemistry Colorado School of Mines  1012 14th Street Golden CO 80401 USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Colin A","family":"Wolden","sequence":"additional","affiliation":[{"name":"Department of Chemical and Biological Engineering Colorado School of Mines  1613 Illinois Street Golden CO 80401 USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1451-2923","authenticated-orcid":false,"given":"Yongan","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Chemistry Colorado School of Mines  1012 14th Street Golden CO 80401 USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2017,6,21]]},"reference":[{"key":"e_1_2_7_1_1","doi-asserted-by":"publisher","DOI":"10.1038\/451652a"},{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1021\/ar2002705"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1038\/nmat3191"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1021\/cm901452z"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/adma.201500180"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1038\/507026a"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1038\/ncomms1843"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.electacta.2011.04.084"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1021\/nl402513x"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpowsour.2015.09.120"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1038\/ncomms11722"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1038\/ncomms2327"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/aenm.201600811"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1021\/nl100504q"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.200907324"},{"key":"e_1_2_7_15_2","doi-asserted-by":"publisher","DOI":"10.1002\/ange.200907324"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1039\/c2jm16802b"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1021\/ja3052206"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.nanolett.5b00112"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.1021\/ja309435f"},{"key":"e_1_2_7_20_1","doi-asserted-by":"publisher","DOI":"10.1002\/aenm.201400196"},{"key":"e_1_2_7_21_1","unstructured":"W.
