In the 21 st century, at a global level, energy and environment are the most important issues. The green approach to solve these issues is photocatalysis. In this regards, perovskite-based materials owing to their inexpensiveness, non-toxicity have attracted significant interest. The photocatalytic activity of perovskite and layered perovskite needs some modification to provide better activity than that of neat one. The modification can be done by replacing cations, formation of heterojunction or formation of composite. This critical review presents and discusses the current development of perovskite, layered perovskite, and their composite especially with π-conjugated carbon materials towards photocatalytic applications. After introduction of the synthesis methods of perovskite and layered perovskite as well as their properties, we focus on the description of various methods to synthesize their composites, mainly those with graphene, carbon nano-tubes and carbon nitrides. Particular importance is placed on strategies for the optimization of composite properties. Lastly, the advantages of perovskite and layered perovskite based composites in applications such as the photocatalytic H 2 production, pollutant degradation are described in details.

“…Cubic mesoporous ordered g-C 3 N 4 as an all-in-one chemosensor was used for the detection of trace amounts metal ions [23]. Semiconductor properties of g-C 3 N 4 nanosheets were explored to design fluorescence sensors for sensitive and selective detection of Cu 2+ [24,25]. Recently, the g-C 3 N 4 has been used as a highly sensitive electrochemical sensor for simultaneous electrochemical detection of Pb 2+ , Cu 2+ and Hg 2+ by modifying glassy carbon electrode [26].…”

We demonstrate that nanosheets composed of graphitic carbon nitride (g-C 3 N 4 ) can serve as a low-cost and efficient fluorescent nanoprobe for the multiplexed detection of DNA in solution. The strategy is based on the finding that g-C 3 N 4 is capable of binding dye-labeled single-stranded DNA (ssDNA) which results in quenching of the fluorescence of the dye. If target DNA hybridizes with dye-labeled ssDNA, the interaction between dye-labeled ssDNA and g-C 3 N 4 is weakened, and this results in desorption of the dsDNA from the surface of the g-C 3 N 4 and in recovery of fluorescence. The large surface area of g-C 3 N 4 nanosheets allows for simultaneous quenching of multicolor DNA probes labeled with different dyes, leading to the development of multiplexed DNA sensors for the detection of multiple DNA targets in a single solution. By using one 15-mer DNA fragment and one 18-mer DNA fragment as proof-of-principle analytes, the method displayed good analytical performance. The limits of detection are 75 and 62 pM, respectively. The method is simple and sensitive, and was used to detect DNA in serum samples. We perceive that this method represents a new approach towards multiplexed assays for applications in DNA monitoring, clinical diagnosis, and in the detection of genetic disorders.
