Universidad de Zaragoza (orcid)0000-0001-8572-1760 Solventless synthesis of ZIF-L and ZIF-8 with hydraulic press and high temperature 2021 Access copy available to the general public Unrestricted In recent years, alternative methods to conventional synthesis of MOFs (metal-organic frameworks) have emerged due to the problematic use of solvents for both the environment and human health. Here we present the synthesis of ZIFs (zeolitic imidazolate frameworks) at high pressure by means of a hydraulic press provided with a heating mechanism. By the optimization of parameters such as temperature, time and the addition of promotor NH4NO3, a considerable increase in the reaction yield was achieved in products, neither washed nor activated, obtained since the first minute of reaction. Depending on the operation conditions, ZIF-L appeared as competing phase with ZIF-8. Upon transformation of ZIF-L into ZIF-8 in presence of ethanol, a reaction yield of 58.2% was achieved to highly crystalline ZIF-8 with a BET specific surface area of 947 m2/g. This green, fast, versatile and improved method suggests a possible way to future synthesis of other MOFs and the possibility of their industrial implementation. info:eu-repo/grantAgreement/ES/DGA-FSE/T43-20R info:eu-repo/grantAgreement/ES/MINECO-AEI-FEDER/MAT2016-77290-R info:eu-repo/grantAgreement/ES/MINECO-AEI-FEDER/PID2019-104009RB-I00/AEI/10.13039/501100011033 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 5.876 2021 CHEMISTRY, APPLIED 15 / 72 = 0.208 2021 Q1 T1 MATERIALS SCIENCE, MULTIDISCIPLINARY 106 / 344 = 0.308 2021 Q2 T1 NANOSCIENCE & NANOTECHNOLOGY 51 / 108 = 0.472 2021 Q2 T2 CHEMISTRY, PHYSICAL 58 / 165 = 0.352 2021 Q2 T2 0.924 2021 Chemistry (miscellaneous) 2021 Q1 Nanoscience and Nanotechnology 2021 Q1 Mechanics of Materials 2021 Q1 Condensed Matter Physics 2021 Q1 8.9 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Reséndiz-Ordóñez, J.U.
