abstract aims: the application of photocatalytic processes to remove heavy metals in aqueous solutions and industrial wastewater are regarded as extremely effective, clean and without producing waste methods. the goal of the present study was to investigate the photocatalytic activity of zno based on h-zsm-5 zeolite support. materials & methods: zno/h-zsm-5 composite synthesized by impregnation...

Transformation of lignocellulosic biomass into high-value chemicals is a viable strategy for sustainable development bio-based economy. 5-Hydroxymethylfurfural (HMF) one potential platform bio-chemicals the manufacture various renewable products. In this work, commercial H-ZSM-5 zeolite was used as starting material preparing series acid catalysts with bifunctionality direct dehydration glucose...

An equilibrated mixture of pentene isomers was produced by dehydroisomerization of n-pentane on catalysts consisting of Pt clusters within [Fe]ZSM-5 channels. These catalysts showed high isomerization rates, excellent stability even without added H2, and isopentene selectivities above 60%. Metal sites on Pt clusters dehydrogenate n-alkanes and n-alkenes formed undergo skeletal rearrangements wi...
