The fruc.ose-to-furfural transformation is fac.ng major c.allenges in the selec.ivity.and high effic.enc.0} Herein, we have developed a simple and effec.ive approac. for the selec.ive c.nversion of fruc.ose to furfural using Hβ zeolite modified by.organic.ac.ds for dealuminization to regulate its textural and ac.dic.properties. It was found that c.tric.ac.d-dealuminized Hβ zeolite possessed high spec.fic.surfac. areas, wide c.annels and high Brønsted ac.d amount, whic. fac.litated the selec.ive c.nversion of fruc.ose to furfural with a maximum y.eld of 76.2% at433 K for 1 h in the γ-buty.olac.one(GBL)-H_(2)O sy.tem, as well as the c.nc.mitant formation of 83.0% formic.ac.d. The^(13)c.isotope labelling experiments and the mec.anism revealed that the selec.ive c.eavage of c.–c. or c.–c. bond on fruc.ose was firstly.oc.urred to form pentose or c. intermediate by.weak Brønsted ac.d, whic. was then dehy.rated to furfural by.strong Brønsted ac.d. Also this dealuminized Hβ c.taly.t showed the great rec.0}ling performanc. and was ac.ive for the c.nversion of gluc.se and mannose.
