Chemiluminescence of the Ce 3+ * ions, and the 1 О 2 and ( 1 О 2 ) 2 molecular species of oxygen induced by active surface of the (NH 4 ) 2 Ce(NO 3 ) 6 crystals at reduction of Ce 4+ to Ce 3+ by water in heterogeneous system «(NH 4 ) 2 Ce(NO 3 ) 6 -C 6 H 6 -H 2 O»

Singlet oxygen-promoted one-pot synthesis of highly ordered mesoporous silica materials via the radical route

“…The formation of 1 O 2 and ˙OH molecular species of reactive oxygen species is induced by the active surface of (NH 4 ) 2 Ce(NO 3 ) 6 crystals via Ce 4+ reduction to Ce 3+ by water. 19 In this case, 1 O 2 could be used to accelerate the hydrolysis of silica species. Herein, a facile one-pot method was reported for the synthesis of highly ordered mesoporous Ce-SBA-15 without acid addition.…”
