“…21,25 Absorptions at around 1242 cm −1 is the nature of protonated PANI. 26 The absorption peak at 797 cm −1 probably due to the vibration of (-NH 2 ) wagging. The absorption peak at 2936 cm −1 is due to anti symmetric CH 2 stretching, another peak at 594 cm −1 is due to C-H bond out-of-plane bending vibration of PANI, 27,28 which shows the presence of substituted benzene.…”

Antimony sulfide (Sb2S3) is an emerging photovoltaic material that comprises earth-abundant, non-toxic constituents and has a high absorption coefficient (>104 cm−1). Nevertheless, the serious bulk recombination phenomenon and the slow electrochemical reaction kinetics on the surface of Sb2S3 electrode restrict its application in the photoelectrochemical (PEC) water splitting. Herein, we have designed a polyaniline (PANI)/Sb2S3 p-n junction photoanode successfully to address these issues. With the modification of in-situ anchored PANI, the composite electrode exhibits enhanced light-absorption and accelerated charge transfer efficiency. As a result, the photocurrent density of optimized PANI/Sb2S3 photoanode is about twice of pristine Sb2S3, being a promising material for PEC water splitting.
