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.

MoS2/g-C3N4 (g-C3N4 [Formula: see text] graphitic carbon nitride) composite is considered as a promising photocatalyst for hydrogen production, while the preparation method still needs to be improved. Herein for the first time, nanosized MoS3 and melamine were used as starting materials and a facile one-pot calcination method was successfully applied for the synthesis of MoS2/g-C3N4. The physical and photophysical properties of the as-prepared MoS2/g-C3N4 were characterized by XRD, IR, SEM, TEM and XPS techniques. Sensitized by Erythrosin B (EB), the photocatalytic hydrogen production performance of MoS2/g-C3N4 was investigated and the amount of MoS2 was optimized. An excellent H2 production activity of 1091.2[Formula: see text][Formula: see text] was achieved for 43% MoS2/g-C3N4, which is about 330 times that of pure g-C3N4 (3.3[Formula: see text][Formula: see text]. In addition, its performance was compared with those of three other MoS2/g-C3N4 samples prepared by conventional methods and a possible mechanism of H2 production was proposed based on the photoluminescence and photoelectrochemical results.
