Visible light induced biohydrogen production from sucrose using the photosensitization of Mg chlorophyll-a

Abstract:
A photoinduced hydrogen production system, coupling sucrose degradation with invertase and glucose dehydrogenase (GDH) and hydrogen production with colloidal platinum as a catalyst using the visible light-induced photosensitization of Mg chlorophyll-a (Mg Chl-a), has been developed. Continuous hydrogen gas production was observed when the reaction mixture containing sucrose, invertase, GDH, nicotinamide adenine dinucleotide (NAD(+)), Mg Chl-a, methyl viologen (MV(2+), an electron relay reagent), and colloidal platinum was irradiated by visible light.

Photons
A photon is a discrete electromagnetic particle or bundle of energy. Photons are characterized by their frequency, wavelength, and amplitude, similar to the properties of a wave. Waves with higher frequencies transmit more energy and have shorter wavelengths than longer wavelengths that transmit less...
