In this regard, increasing surface area and decreasing dimensions of catalysts have been widely employed on account of effectiveness of these methods. Herein, aerogel form of chitosan as a sustainable, and high aspect ratio compound is employed as a green support for the catalytic purposes. Chitosan aerogel was modified with Fe(II)-phthalocyanine to produce a heterogeneous catalyst for oxidation reactions. The synthesized catalyst promoted the oxidation reactions of alcohols and alkyl arenes to the corresponding aldehydes and ketones using H\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>2<\/jats:sub>\n                    as an oxidant in 24\u00a0h. The reactions for aliphatic and aromatic alcohols gave turnover numbers of 106\u2013109 at 80\u00a0\u00b0C and 106\u2013117 at room temperature, respectively. The oxidations of alkyl arenes were carried out with turnover numbers laying in the range of 106\u2013117 at 100\u00a0\u00b0C. The low toxicity, inexpensive nature, and recycling possibility of the catalyst accompanied by the reaction mild conditions, clean oxidant, and excellent yields offer chitosan aerogel modified with Fe(II)-phthalocyanine as a promising catalyst for oxidation reactions.\n                  <\/jats:p>","DOI":"10.1038\/s41598-021-03226-7","type":"journal-article","created":{"date-parts":[[2021,12,9]],"date-time":"2021-12-09T06:12:09Z","timestamp":1639030329000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Fe(II)-phthalocyanine supported on chitosan aerogel as a catalyst for oxidation of alcohols and alkyl arenes"],"prefix":"10.1038","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3503-031X","authenticated-orcid":false,"given":"Fatemeh","family":"Azimi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5899-4285","authenticated-orcid":false,"given":"Ahmad","family":"Poursattar Marjani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3545-2907","authenticated-orcid":false,"given":"Sajjad","family":"Keshipour","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2021,12,9]]},"reference":[{"key":"3226_CR1","doi-asserted-by":"publisher","first-page":"8152","DOI":"10.1021\/cr4000072","volume":"113","author":"AB Sorokin","year":"2013","unstructured":"Sorokin, A.
