Perovskite Oxide–Based Materials for Photocatalytic and Photoelectrocatalytic Treatment of Water

Abstract

Meeting the global challenge of water availability necessitates diversification from traditional water treatment methods to other complementary methods, such as photocatalysis and photoelectrocatalysis (PEC), for a more robust solution. Materials play very important roles in the development of these newer methods. Thus, the quest and applications of a myriad of materials are ongoing areas of water research. Perovskite and perovskite-related materials, which have been largely explored in the energy sectors, are potential materials in water treatment technologies. In this review, attention is paid to the recent progress in the application of perovskite materials in photocatalytic and photoelectrocatalytic degradation of organic pollutants in water. Water treatment applications of lanthanum, ferrite, titanate, and tantalum (and others)-based perovskites are discussed. The chemical nature and different synthetic routes of perovskites or perovskite composites are presented as fundamental to applications.

Application of Materials Genome Methods in Thermoelectrics

“…Since the discovery of p-type NaCo 2 O 4 with high TE performance (Terasaki et al, 1997), many oxides, such as the binary oxide ZnO (Ong et al, 2011) and the perovskite-type oxides SrTiO 3 (Muller et al, 2004), CaMnO 3 (Wang et al, 2009), and LaCoO 3 (Vulchev et al, 2012), have been investigated as TE materials. The hightemperature stability, environmentally friendly properties, and low cost make them suitable for various applications, such TE, photoelectric, catalysis, photocatalytic (Sawada and Nakajima, 2018;Nkwachukwu and Arotiba, 2021), and dielectric materials. Unlike the favored materials in the field of TE, such as SnSe (Wang et al, 2015;Zhao et al, 2016), PbTe (Pei et al, 2011;Xiao and Zhao, 2018), and Cu 2 Se (Nunna et al, 2017;Olvera et al, 2017), the ZT values of oxides were not very high (Wang H. C. et al, 2011;Wang J. et al, 2017).…”

Analysis of the Applications of Particle Swarm Optimization and Genetic Algorithms on Reaction Kinetics: A Prospective Study for Advanced Oxidation Processes

“…[47] Because of these, it have been a challenging task to synthesize a material with superior qualities accounting to all of the above mentioned requirements. However, promising advances have been already reported for the implementation of metal-organic frameworks (MOFs), [48,49] perovskite oxides, [50,51] doped semiconductors, [52,53] and photo-sensitized materials. [54][55][56] When modeling photocatalytic processes, two main factors need to be considered: (i) the light absorption on the catalyst ChemElectroChem and (ii) the concentration of pollutants.…”

A Review on Synthesis, Properties, and Environmental Application of Fe-Based Perovskite

“…e magnetic and electrical properties of ferrite-based Perovskite draw interest. Due to a distortion in their crystal structures, they feature an intrinsic electric dipole moment, which enhances the separation of photo-generated charges during the photoexcitation process [105].…”
