1. A one-step process for converting sugars to platform chemicals, the one-step process comprising reacting a sugar with a physical mixture of a Lewis acid catalyst and a Bronsted acid catalyst at a temperature from 100° C. to 250° C. for 0.5 h to 7 h in an alcohol to obtain the platform chemicals with a reaction product yield from 60% to 85%, wherein:
the Lewis acid catalyst comprises Lewis acid catalyst particles;
the Bronsted acid catalyst comprises Bronsted acid catalyst particles; and
the physical mixture of the Lewis acid catalyst and the Bronsted acid catalyst comprises a combination of the Lewis acid catalyst particles and the Bronsted acid catalyst particles showing a mixed morphology.
