Implication

Experimental study demonstrates conversion of dissolved cellulose to 5-hydroxymethylfurfural in a corrugated TiO2 reactor, indicating an energy-efficient pathway for biomass valorization.

Key Points

To investigate the photocatalytic degradation of dissolved cellulose into 5-hydroxymethylfurfural under ultraviolet irradiation using a titanium dioxide-coated corrugated plate reactor.
Dissolved 10 g of natural cellulose in 100 mL of 66% ZnCl2 solution.
Conducted photodegradation in a corrugated plate photocatalytic reactor equipped with a 21 W UV lamp, evaluating a 42° plate angle and nine TiO2 coating cycles across a 2-hour irradiation period.
The yield of 5-hydroxymethyl furfural (5-HMF) reached 3.87 g L−1 under optimal reactor conditions.
The energy efficiency per mass (EE/M) for cellulose degradation was measured at 10.9 kWh kg−1, facilitated by enhanced catalyst surface illumination and photon capture.
