Additionally, it promotes the synthesis of valuable organic compounds from bioethanol. This study investigated the use of green-synthesized NiO nanoparticles as a catalyst for ethanol dehydrogenation. The highest selectivity for hydrogen production (97.4%) was achieved using 10% NiO at 260\u00a0\u00b0C. However, at 10% NiO and 280\u00a0\u00b0C, the fuel gas mixture yielded a higher calculated calorific value (1,231.6\u00a0kJ). This condition was used to evaluate the reaction\u2019s kinetic over a period of 1 to 8 reaction-hours. During these experiments, a progressive increase in gas volume was observed, along with a transition in the gas products from propane to hydrogen, followed by methane. These changes correlated with ethanol conversion to organic compounds (1,1-diethoxyethane and 1-butanol) in the liquid phase, as well as catalyst\u2019s crystal structure alterations, from Ni\n                    <jats:sup>2+<\/jats:sup>\n                    face-centered-cubic (FCC) to metallic nickel FCC and hexagonal close-packed (HCP) phase.\n                  <\/jats:p>","DOI":"10.1007\/s11356-026-37421-8","type":"journal-article","created":{"date-parts":[[2026,4,16]],"date-time":"2026-04-16T06:04:04Z","timestamp":1776319444000},"page":"6861-6876","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Renewable fuel gases and important organic compounds production from ethanol dehydrogenation using nickel oxide, a green-synthesized catalyst"],"prefix":"10.1007","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4035-8755","authenticated-orcid":false,"given":"Carla Maria Beraldi","family":"Gomes","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Denise Aparecida","family":"Zempulski","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Caroline","family":"da Ros Montes D\u2019Oca","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Helton Jos\u00e9","family":"Alves","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2026,4,16]]},"reference":[{"key":"37421_CR1","unstructured":"Associa\u00e7\u00e3o Brasileira de Normas T\u00e9cnicas (ABNT) (2018) NBR 11348\u20131 - Produtos l\u00edquidos de petr\u00f3leo \u2013 Determina\u00e7\u00e3o do teor de \u00e1gua pelo reagente de Karl Fischer \u2013 Parte 1: M\u00e9todo volum\u00e9trico.
