dc.description.abstract [EN] In the hydrothermal crystallization of zeolites from basic media, hydroxide ions (OH-) catalyze the depolymerization of the aluminosilicate gel by breaking the Si, Al-O-Si, Al bonds and catalyze the polymerization of the aluminosilicate anions around the hydrated cation species by remaking the Si, Al-O-Si, Al bonds. We report that hydroxyl free radicals (center dot OH) are involved in the zeolite crystallization under hydrothermal conditions. The crystallization processes of zeolites-such as Na-A, Na-X, NaZ-21, and silicalite-1-can be accelerated with hydroxyl free radicals generated by ultraviolet irradiation or Fenton's reagent. es_ES
dc.description.sponsorship This work was supported by the 973 Project (grants 2014CB931802 and 2013CB921802) and the National Natural Science Foundation of China (grants 21320102001, 91122029, and 21571075). A.C. thanks the Program Severo Ochoa for financial support and ERC-AdG-2014-671093-SynCatMatch. J.Y. designed and supervised the project; W.Y., A.C., and R.X. involved the design of the experiments; G.F., P.C., and J.W. performed the experiments; J.-H.S. performed the EPR analyses; M.B., X.L., and Y.L. contributed to the calculations; J.Y. and W.Y. analyzed the data; G.F. wrote the first draft; and J.Y. and W.Y. deeply revised the manuscript. A Chinese patent about the method for UV-assisted synthesis of zeolite materials has been applied for. es_ES
