Bimodal-HZ-5 zeolite obtained by post-synthesis modification of H-ZSM-5 with desilication was found to be a potential heterogeneous catalyst with 67% cellulose conversion and 46% yield of 5-HMF. Bimodal-HZ-5 was observed to be reusable for four cycles, without any loss in activity. The detailed optimization of process parameters and catalyst reusability are also presented. The present study opens a new avenue for the renewable one-pot synthesis of 5-HMF, a valuable product.</p>10a5-Hydroxymethylfurfural10aBiomodal-HZ-510aglucose10aHydrolysis10aMicrocrystalline cellulose1 aNandiwale, Kakasaheb, Y.1 aGalande, Nitish, D.1 aThakur, Pratika1 aSawant, Sanjay, D.1 aZambre, Vishal, P.1 aBokade, Vijay, V.  uhttps://library.ncl.res.in/content/one-pot-synthesis-5-hydroxymethylfurfural-cellulose-hydrolysis-over-highly-active-bimodal-0
