“… 39 These peaks are in good agreement with the ref. 39 and 40 upon the addition of GQDs. It is observed that some diffraction intensity of peaks is increased or decreased slightly compared to CdS sample.…”

“…Additionally, it has been shown that only a minority of the electron–hole pairs participate in the photocatalytic reaction, and the large over potential on the surface of CdS also disfavor on-pathway catalysis. 39,48,49 The results indicate that there is a general trend of increasing RhB degradation efficiency with increasing loading of GQDs. The CdS-4 sample exhibits the highest dye degradation efficiency of 74.4%, which is 1.6 times higher than that of pure CdS.…”

An overview of the significant innovations in photocatalysts for H 2 development, photocatalyst selection criteria, and photocatalytic modifications to improve the photocatalytic activity was examined in this Review, as well as mechanisms and thermodynamics. A variety of semiconductors have been examined in a structured fashion, such as TiO 2 -, g-C 3 N 4 -, graphene-, sulfide-, oxide-, nitride-, oxysulfide-, oxynitrides, and cocatalyst-based photocatalysts. The techniques for enhancing the compatibility of metals and nonmetals is discussed in order to boost photoactivity within visible light irradiation. In particular, further deliberation has been carried out on the development of heterojunctions, such as type I, type II, and type III, along with Z-systems, and S-scheme systems. It is important to thoroughly investigate these issues in the sense of visible light irradiations to enhance the efficacy of photocatalytic action. In fact, another advancement in this area may include hiring mediators including grapheme oxide and metals to establish indirect Z-scheme montages with a correct band adjustment. The potential consideration of reaction chemology, mass transfer, kinetics of reactions, restriction of light diffusion, and the process and selection of suitable light and photoreactor also will optimize sustainable hydrogen output efficiency and selectivity.

“…Hence, the development of nonprecious and metal-free materials is essential. Low-cost and earth-occurring transition metals such as Cu, − Ni, and Co , are examples of nonprecious elements that have been successfully used as cocatalysts in HER. Carbon-based supports such as graphitic carbon nitride (g-C 3 N 4 ), graphene and its derivatives, − as well as an organohydride-catalyst may also enhance photocatalytic CO 2 reduction performance by overcoming the limitation faced by a traditional photocatalyst through their suitable physiochemical and electrical properties like high surface area, stability, anticorrosion capacity, photosensitivity, and conductivity.…”

Photoelectrochemical water splitting and CO2 reduction provide an attractive route to produce solar fuels while reducing the level of CO2 emissions. Metal halide perovskites (MHPs) have been extensively studied for this purpose in recent years due to their suitable optoelectronic properties. In this review, we survey the recent achievements in the field. After a brief introduction to photoelectrochemical (PEC) processes, we discussed the properties, synthesis, and application of MHPs in this context. We also survey the state-of-the-art findings regarding significant achievements in performance, and developments in addressing the major challenges of toxicity and instability toward water. Efforts have been made to replace the toxic Pb with less toxic materials like Sn, Ge, Sb, and Bi. The stability toward water has been also improved by using various methods such as compositional engineering, 2D/3D perovskite structures, surface passivation, the use of protective layers, and encapsulation. In the last part, considering the experience gained in photovoltaic applications, we provided our perspective for the future challenges and opportunities. We place special emphasis on the improvement of stability as the major challenge and the potential contribution of machine learning to identify the most suitable formulation for halide perovskites with desired properties.
