The anchored location of CdS on SiC via organosilane for effective heterogeneous interface design in photocatalysis
This work demonstrates a new approach to construct a heterogeneous junction by means of the periodic lattice distribution of semiconductor atoms. The organosilane was applied as an anchored coupling agent to connect the semiconductors at both ends, one of which connects SiC and the other connects CdS, and the SiC/M/CdS heterogeneous junction was established. The photocatalytic hydrogen evolution ability of this heterojunction was three times as much as the traditional SiC/CdS composite under visible light. Meanwhile, the uniform interface distribution, prolonged charge-carrier lifetime and minor electron–hole recombination were achieved. The results provide new insights into interface design and offer an indepth understanding with respect to organic–inorganic heterojunction configuration in photocatalysis.
