Photocatalytic Hydrogen Production

This study investigated the effects of constituents in bio/photocatalytic hydrogen production system using an experimental design tool, a fractional factorial design. The factors considered included species of buffer solution, the amount of hydrogenase (Pyrococcus furiosus, Pfu), electron donor, reaction temperature and electron mediator. The experiments were designed to determine critical conditions that were required to achieve the highest level of H2 production.

Dual Bed

A new dual-bed photocatalytic hydrogen production reaction system is proposed in this paper. In this dual-bed system, one bed is photocatalytic hydrogen evolution reaction bed in which I- is oxidized into I2 by a hole and H+ is reduced to H2 by an electron, and the other is the hole-sacrificed agent regeneration bed in which I- is regenerated by reducing I2 with Cu2O. The two reaction beds are connected with two constant flow pumps to form a circulation loop. The hole-sacrificed agent I- can always be renewable by circulating the reaction solution between dual beds. The dual-bed reaction system achieves to produce hydrogen continuously, steadily and efficiently.
