摘要
High-performance composite electrocatalysts of g-C3N4/FeS2/MoS2 for hydrogen evolution reaction (HER) is synthesized by the growth of molybdenum disulfide (MoS2) nanosheets from ferrous disulfide (FeS2) sites supported on graphite-like carbon nitride (g-C3N4) substrates. The high conductivity of such composite catalysts is induced by the Fe-S bond between FeS2 and MoS2 and Fe-N bond between FeS2 and g-C3N4. These two bonds of Fe-S and Fe-N can have a bridging function to provide efficient charge transfer channels between g-C3N4 and MoS2 via chemical bonding rather than physical attachment. Furthermore, the FeS2 sites can prevent the agglomeration of MoS2 nanosheets and also seed the MoS2 to form highly dispersed vertical growth nanosheets with more exposed edging active sites. As a result, this g-C3N4/FeS2/MoS2 catalyst exhibits both high catalytic HER activity and stability.
