Ethylene was selected as target pollutant due to the importance of its removal in the control of climacteric fruit ripening. Activated carbons (ACs) were obtained by physical activation in CO2 from baru waste and used either as adsorbents of ethylene, or as support of MnxOy nanoparticles to obtain active photocatalysts by simple incipient impregnation. All samples were characterized by complementary techniques (physical adsorption of CO2 and N2, XRD, SEM-EDX, FTIR, XPS, TG-DTG). Adsorption and photocatalytic assays were carried out in continuous fixed bed reactors. Breakthrough curves for ethylene adsorption were recorded in 100 ppm ethylene, air flow (25 cm3 min\u20131) and under both dry and humid (RH = 50%) conditions. After saturation, the photo-oxidation of ethylene was studied under visible radiation at room temperature. The results indicated that, under these experimental conditions, the reaction proceeds selectively to CO2, with ethylene removal increases with MnxOy content in the presence of humidity, reaching complete conversion at 10 wt.%.<\/jats:p>","DOI":"10.2139\/ssrn.6360794","type":"posted-content","created":{"date-parts":[[2026,3,6]],"date-time":"2026-03-06T20:40:14Z","timestamp":1772829614000},"source":"Crossref","is-referenced-by-count":0,"title":["Towards the sustainable preservation of climacteric fruit by ethylene removal using MnxOy-carbon composites derived from agrifood waste"],"prefix":"10.2139","author":[{"given":"Ana  Carolina J.","family":"Oliveira","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0914-1139","authenticated-orcid":true,"given":"Sergio","family":"Morales-Torres","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7037-3417","authenticated-orcid":true,"given":"L.M.","family":"Pastrana-Mart\u00ednez","sequence":"additional","affiliation":[]},{"given":"Tatiane  F. de","family":"Oliveira","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2468-8407","authenticated-orcid":true,"given":"Francisco  J.","family":"Maldonado-H\u00f3dar","sequence":"additional","affiliation":[]}],"member":"78","reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"5029","DOI":"10.1021\/cr900398v","article-title":"Ethylene Removal and Fresh Product Storage: A Challenge at the Frontiers of Chemistry.
