Owing to the creation of a large number of surface active sites, surface modification is an efficient strategy for improving the catalytic performances of photocatalysts. Herein, zero-dimensional (0D) p-type NiS species were developed in situ on the large surface of NiAl-LDH by controlled vulcanization. Importantly, the development of the 0D p-type NiS species not only enriched the active sites but also triggered the in situ formation of a NiS/NiAl-LDH p−n heterojunction due to NiAl-LDH, which was utterly underdeveloped in the vulcanization modification procedure. This undoubtedly accelerated the faster separation and migration of charge carriers and yielded improved photocatalytic hydrogen evolution. The optimum hydrogen production rate of the NiS/NiAl-LDH photocatalyst could reach 3408 μmol•g −1 •h −1 using a 5 W LED simulation visible light, which was 52-fold that of NiAl-LDH. The design and construction of the in situ p−n heterojunction may provide a perspective for the formation of p−n heterojunction photocatalysts with a closer contact interface and highly enhanced photocatalytic activity.

“…But in the identical experimental condition when RGO-CdTe composite was used the degradation reached 83.6% for the same period of illumination. The photocatalytic degradation of TC follows a pseudo-first-order kinetic reaction process, and the pseudo-first-order kinetic constant or the degradation rate constant k (min −1 ) was calculated by the equation: 57 , 58 . Figure 4 B shows the variation of with the illumination time.…”

RGO-CdTe composite was synthesized using a straightforward, easy-to-realize, one-pot solvothermal technique. The synthesized composite was characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), Brunauer-Emmett-Teller method (BET), Raman spectra, UV-Vis absorption, and photoluminescence measurement. The RGO-CdTe composite exhibited 83.6% photocatalytic degradation efficiency for the aqueous tetracycline (TC) antibiotic solution and the apparent quantum yield (AQY) for the same was as high as 22.29% which is 2.63 times higher than that of CdTe. The scavenger investigation demonstrated that although hole acts as the leading active species, despite that, superoxide and hydroxyl radicals have also played crucial roles. The initial pH-dependent photocatalytic performance was measured. The zeta potential of the composite at different pH values was evaluated to establish the photocatalytic performance of the RGO-CdTe towards TC degradation at different pH. The recycling experiment depicts that only a 10% degradation performance declines after 5 times recycle use of the RGO-CdTe photocatalyst. An efficient photocurrent generation in RGO-CdTe thin film device has also been observed. Our study establishes as-synthesized composite of RGO-CdTe as a highly potential, and stable photocatalyst for the degradation of antibiotics from the polluted aqueous environment with a very good photoinduced charge generation efficiency in its solid phase.
