a ZEOL-Coked sample. b ZEOL-Coked@N2 sample. c ZEOL-Coked@H2O-40 min sample d ZEOL-Coked@H2O-350 min sample. e–g Deactivated samples of ZEOL-Coked@N2, ZEOL-Coked@H2O-40 min and ZEOL-Coked@H2O-350 min used for MTO reaction, respectively. Scale bar represents 10 μm. The SIM images shown is the fluorescence that originated from the overlap of four profiles with a laser excitation of 405 nm (detection at 435–485 nm, false color: blue), 488 nm (detection at 500–545 nm, false color: green), 561 nm (detection at 570–640 nm, false color: red), 640 nm (detection at 663–738 nm, false color: pink).
