Özet
In photocatalytic hydrogen evolution reactions, SiC catalyst was templated with biopolymers (cellulose, chitin, chitosan, sodium alginate) in a reaction medium containing eosin Y dye and triethanolamine. Biopolymers act as biotemplate and mediator, provide easy dispersion, hydrophilicity, morphological transformation and adhesion to semiconductor with the help of functional groups. The photo-deposition of MoS<inf>x</inf> and Pt in aqueous solution is performed on biopolymer-SiC nanocomposite to obtain biopolymer-SiC/MoS<inf>x</inf> and biopolymer-SiC/Pt by reducing (NH<inf>4</inf>)<inf>2</inf>MoS<inf>4</inf> and H<inf>2</inf>PtCl<inf>6</inf>·6H<inf>2</inf>O, respectively. Sodium alginate-SiC/MoS<inf>x</inf> showed highest photocatalytic activity which is approximately 158-, 34- and 13 times higher than bare SiC, bare sodium alginate and sodium alginate-SiC catalyst, respectively. Moreover, the solar-to-hydrogen efficiencies are achieved about 19.83% under solar light irradiation for the sodium alginate-SiC/MoS<inf>x</inf> catalyst. In addition, photo-deposited MoS<inf>x</inf> and Pt on biopolymer-SiC nanocomposite resulted in enhanced photocatalytic activity and stability because of increased active sites and enhanced electron transfer ability due to the co-catalyst effect.
