近日,中国科学院精密测量科学与技术创新研究院徐君报道了ZSM-5沸石上活性骨架Lewis酸位的鉴定。 本文要点 要点1.研究人员用三甲基氧化膦探针分子的一维(1D)31P和二维(2D)31P- {27Al}核磁共振谱确定了与羟基键合的骨架三配位Al的结构。 要点...
Carbonaceous deposits (coke) formed on zeolites H-ZSM-5 and Linde L during methanol conversion at 460掳C have been studied with transmission electron microscopy (TEM). At ca. 6% (w/w) of coke, deposits could just be detected, and at ca. 10% (w/w) the zeolite was enveloped in coke ...
The present work investigates, for the first time, the synthesis of a composite film based on glutaraldehyde-cross-linked chitosan (GA-CS) and a natural zeolite (H-ZSM-5) and its application for the removal of hexavalent chromium (Cr(VI)) from aqueous solutions under wide experimental conditio...
