Perovskite Structure Associated with Precious Metals: Influence on Heterogenous Catalytic Process

Abstract

The use of perovskite-based materials and their derivatives can have an important role in the heterogeneous catalytic field based on photochemical processes. Photochemical reactions have a great potential to solve environmental damage issues. The presence of precious metals in the perovskite structure (i.e., Ag, Au, or Pt) may improve its efficiency significantly. The precious metal may comprise the perovskite lattice as well as form a heterostructure with it. The efficiency of catalytic materials is directly related to processing conditions. Based on this, this review will address the use of perovskite materials combined with precious metal as well as their processing methods for the use in catalyzed reactions.

Efficient photoselectrochemical hydrogen production utilizing of APbI 3 (A = Na, Cs, and Li) perovskites nanorods

“…These materials are organic and non-organic compounds with X halide has the crystalline structure ABX 3 , A and B are two cation. 20,21 Perovskite has excellent carrier transport, high absorption coefficients, long exciton lifetime, excellent charge mobilities, long hole-electron diffusion length, high stability, and tunable bandgap. [22][23][24] Also, they can be easily fabricated by various processes at room temperature under an ambient atmosphere at a low cost.…”

“…Over the past years, perovskite (PSK) nanomaterials have attracted researchers' interest in the photoelectrochemical (PEC) water splitting due to their unique properties. These materials are organic and non‐organic compounds with X halide has the crystalline structure ABX 3 , A and B are two cation 20,21 . Perovskite has excellent carrier transport, high absorption coefficients, long exciton lifetime, excellent charge mobilities, long hole‐electron diffusion length, high stability, and tunable bandgap 22‐24 .…”

The Influence of Photocatalytic Reactors Design and Operating Parameters on the Wastewater Organic Pollutants Removal—A Mini-Review

“…The basic composition includes a mono-component photocatalyst such as TiO 2 [40], WO 3 [41], ZnO [42], Cu 2 S [43], etc. Even optimized by doping or surface photosensitization, these materials exhibit disadvantages related to charge recombination, limited absorption range and low chemical stability [44][45][46]. The multi-component photocatalyst, called heterostructures, benefit from the extended light spectra being able to use UV, visible or near infra-red photoexcitation depending on their energy band gaps values and ability to produce oxidative radicals involved in organic pollutants removal.…”

Converting Sewage Water into H2 Fuel Gas Using Cu/CuO Nanoporous Photocatalytic Electrodes

“…Most of the previous studies on CuO relied on the use of an additional sacrificing agent such as Na 2 SO 3 , Na 2 S 2 O 3 , HCl, and NaOH [26][27][28]. Moreover, the H 2 rate production was limited [29][30][31][32].…”
