Introduction Photocatalysis offers a green solution to many of our environmental problems such as water purification, hydrogen production, organic transformation, and the decomposition of harmful organic dyes [1,2,3,4]. TiO2, in anat...
This paper for the first time reveals the key properties of the most active zeolite catalysts for this reaction. Among many solid acid catalysts studied, acidic Beta zeolites were found to stand out in their performance for the reaction. In this work, several acidic Beta zeolites (HBeta) from...
