“…In this context, different silica-supported semiconductor nanocomposites with improved photocatalytic performance than the corresponding single-component materials have been reported. Examples of silica-supported photocatalysts include SiO 2 /TiO 2 [63,72,123,124] SiO 2 /TiO 2 /CdS [125], SiO 2 /C 3 N 4 [126], SiO 2 /TiO 2 /C 3 N 4 [36] , SiO 2 /WO 3 [127] , SiO 2 /CuO [128,129], SiO 2 /ZnIn 2 S 4 [130] , SiO 2 /ZnO [131], SiO 2 /Ag 3 PO 4 [132] and SiO 2 /FAPbBr 3 [133] among others. While this wide variety of studies clearly demonstrates that silica is outstanding insulating support for the design of photocatalytic systems for energy and environmental applications, the origins of improved photocatalytic performance are debatable and often attributed to a combination of factors, including increased adsorption of reactant molecules, improved structural and textural properties, increased photonic efficiency related to optical scattering as well as changes in the electronic structure of the resulting support-photocatalyst systems [27,55,121].…”

Heterogeneous photocatalysis employing semiconductor oxide photocatalysts is a sustainable and promising method for environmental remediation and clean energy generation. In this context, nanostructured photocatalysts, with at least one dimension in the 1-100 nm size regime, have attracted ever-growing attention due to their unique and often enhanced sizedependent physicochemical properties. While their reduced size ensures enhanced photocatalytic performance, the same makes it difficult and time/energy-demanding to remove/recover such nanostructured photocatalysts from aqueous media. This fundamental limitation has paved the way towards developing supported nanophotocatalysts where the active photocatalytic nanostructures are coated on the surface of polymeric or inorganic support materials, often in a core@shell conformation. This arrangement solves the problem of photocatalysts' recovery for effective reuse or recycling and leads to improved and desired target properties due to specific photocatalyst-support interactions. While the enhanced physicochemical properties of supported photocatalysts have been widely studied in many target applications, the role of support-photocatalysts interactions in improving these properties remains unexplored. This review article provides an updated viewpoint on the photocatalyst-support interactions and the resulting unique physiochemical properties important for diverse photochemical applications and the design of practical devices. While exploring the properties of supported nanostructured metal oxide/ sulfides photocatalysts such as TiO 2 and MoS 2 , we also briefly discuss the common strategies employed to coat the active nanomaterials on the surface of different supports (organic/polymeric, inorganic, active, inert, and magnetic).

“…[6][7][8][9][10][11] At present, some researchers have witnessed the successful utilization of metal halide perovskite as photocatalysts in the elds of the degradation of organic pollutants, hydrogen production, and reduction of CO 2 or NO. [12][13][14][15][16] Driven by the unique attributes of metal halide perovskites and toxicity concerns of Pb, research efforts to develop lead-free halide perovskites have been made over the past few years. [17][18][19] Although a variety of lead-free halide perovskites have been reported over the past several years, there are a few reports about lead-free perovskites in the photocatalytic eld due to their instability and discrepancy between their structures and photocatalytic performance.…”

Bromine-based hybrid perovskites exhibit excellent performance as the top layer of tandem cells, but their overall efficiency as single-junction devices is still very limited. In this work, trimethylolpropane ethoxylated triacrylate (TET), which can form a cross-linking polymer at the grain boundary after heating at 150 °C, is introduced as an additive in FAPbBr3-based perovskite solar cells. The FAPbBr3 film with TET exhibits pinhole-free crystal grains with a large grain size. With a concentration of 5 mg/mL TET, the average grain size increases from 313 to 505 nm. What is more, Raman spectroscopy and X-ray photoelectron spectroscopy demonstrate that the cross-linked TET has a strong interaction with FAPbBr3, which can passivate the defects of grain boundaries. Therefore, the FAPbBr3-based perovskite solar cells with TET achieve a power conversion efficiency of 8.93%. As we know, this is the highest value in FAPbBr3-based hybrid perovskites with an inverted planar structure. This work provides a new insight into the in situ cross-linking additive TET, which only exists at the grain boundary, does not enter the lattice, and has a crystallization control and defect passivation effect on FAPbBr3 thin films, which will provide a new direction for further improving the performance of FAPbBr3 perovskite solar cells.
