Halide perovskite nanomaterials have demonstrated promising potential in various fields, including photocatalysis for environmental remediation. However, perovskites' poor stability toward water makes it difficult to use them for the photocatalytic degradation of organic pollutants in wastewater. Herein, we develop a facile and scalable NaBr-assisted room-temperature aqueous phase procedure for the synthesis of all-inorganic CsPbBr 3 -embedded PbBr(OH) with controlled hierarchical structures, excellent ambient stability, and strong activity for photocatalytic degradation of dyes (e.g., methyl orange and methylene blue) in simulated organic wastewater. It is exceptional that the added NaBr can complex PbBr 2 to form a transparent aqueous solution, enabling the subsequent reaction with the aqueous Cs 2 CO 3 precursor to produce CsPbBr 3 -embedded PbBr(OH) microflowers and microspheres. The photocatalysis shows that the CsPbBr 3 -embedded PbBr(OH) photocatalysts exhibit excellent photocatalytic activity for dye degradation under visible-light irradiation, which is significantly stronger than that of commercial TiO 2 and some other perovskite-based materials produced using a previously reported method. The excellent stability of the CsPbBr 3 -embedded PbBr(OH) as a photocatalyst is verified by nine consecutive photocatalytic cycles without a noticeable drop in photodegradation efficiency. This work will shed light on the green synthesis of ultra-stable perovskite-based nanomaterials for photocatalytic degradation of organic pollutants as well as other promising water treatment technology prospects.

“…Inside these very broad categories, several aspects have been considered. If Humayun et al [ 29 ] pointed out the synthesis procedures of composite photocatalysts and the use of microwave is underlined, other works focalize on a specific class of materials: MOF [ 25 ], metal halide perovskite [ 26 ], graphene [ 28 ], and carbon nitride [ 30 ].…”

Heterogeneous photocatalysts have garnered extensive attention as a sustainable way for environmental remediation and energy storage process. Water splitting, solar energy conversion, and pollutant degradation are examples of nowadays applications where semiconductor-based photocatalysts represent a potentially disruptive technology. The exploitation of solar radiation for photocatalysis could generate a strong impact by decreasing the energy demand and simultaneously mitigating the impact of anthropogenic pollutants. However, most of the actual photocatalysts work only on energy radiation in the Near-UV region (<400 nm), and the studies and development of new photocatalysts with high efficiency in the visible range of the spectrum are required. In this regard, hybrid organic/inorganic photocatalysts have emerged as highly potential materials to drastically improve visible photocatalytic efficiency. In this review, we will analyze the state-of-art and the developments of hybrid photocatalysts for energy storage and energy conversion process as well as their application in pollutant degradation and water treatments.

“…[ 1–3 ] Owing to their excellent photoelectric properties, these perovskites have been recently used in extensive studies. [ 4–6 ] However, the organic cations in organic–inorganic halide perovskites are very sensitive to high temperatures and moisture, leading to poor device stability in ambient environments. Fortunately, all‐inorganic halide perovskites (AIHPs) exhibit better stability as they are configured without any organic cations.…”

All‐inorganic halide perovskites (AIHPs) are promising photovoltaic materials that have been extensively studied in the last decade. In addition, lead‐free AIHPs are preferred because of their non‐toxic and environmentally friendly nature. However, the quality of AIHPs fabricated by conventional solution processing methods is usually unsatisfactory, which leads to poor photoelectric performance. Herein, a facile polydimethylsiloxane‐assisted slow evaporation method that can be readily used to synthesize high‐quality AIHP microcrystals (MCs) (CsPbBr3, Cs2AgBiBr6, and L‐Cs3Sb2I9) is demonstrated. The photodetection properties of the synthesized AIHP MCs and their spin‐coated thin‐film counterparts are thoroughly studied and compared. Owing to their superior crystallinity, AIHP MCs show better photoelectric performance than spin‐coated films. The responsivity of the CsPbBr3 microcrystal photodetectors is ≈590 000 mA W−1. This work proposes a universal solution‐processing method for the successful fabrication of high‐quality all‐inorganic lead‐based (CsPbBr3), lead‐free (L‐Cs3Sb2I9), and double (Cs2AgBiBr6) perovskites, which can overcome the bottleneck in the development of halide perovskites and promote their applications.
