Three-dimensionally ordered macroporous perovskite materials for environmental applications

Abstract

Three-dimensionally ordered macroporous (3DOM) perovskite materials have attracted the interest from researchers worldwide due to their unique macroporous structure, flexible composition, tailorable physicochemical property, high stability and biocompatibility. In particular, they were widely used in environmental field, such as photocatalysis, catalytic combustion, catalytic oxidation and sensors. In this review, the recent progresses in the synthesis of 3DOM perovskite materials and their environmental applications are summarized. The advantages and the promoting mechanisms of 3DOM perovskite materials for different applications are discussed in detail. Subsequently, the challenges and perspectives on the topic are proposed.

Current State of Porous Carbon for Wastewater Treatment

“…As these materials have fairly large pores (dp> 50 nm), they find their use in the field of decontamination of polluted water with organic dyes and as a catalyst support for the photodegradation of the pollutant [20,[38][39][40][41].…”

Z-scheme N-doped K4Nb6O17/g-C3N4 heterojunction with superior visible-light-driven photocatalytic activity for organic pollutant removal and hydrogen production

“…Photocatalysis has been widely investigated, and is generally considered to be one of the "green" approaches for solving the problems of environmental pollution and energy shortages [1]. Various semiconductor photocatalysts, such as layered niobate, polymeric carbon nitride (g-C3N4), perovskite materials, TiO2, and MoS2, have been carefully constructed and applied in organic dye degradation, H2 generation, and CO2 reduction [2][3][4][5]. Among these semiconductor photocatalysts, the typical layered compound K4Nb6O17, which contains NbO6 units connected by bridging oxygen atoms [6], has been investigated extensively for photocatalytic applications because of its appealing electronic band structure, easy structural modification, and favorable charge transfer capacity [7][8][9].…”

Design of a ZnO/Poly(vinylidene fluoride) inverse opal film for photon localization-assisted full solar spectrum photocatalysis

“…Among the different types of PC, opal and inverse opal (IO) structures have been widely researched due to their excellent optical performance. Owing to its PBG and slow light effects, PC structure has attracted great interest due to its potential application for improving light harvesting in photocatalysis [33][34][35][36]. The PBG effect can be described as light within the wavelength region of the PBG being forbidden from propagating in the PC on the grounds of Bragg diffraction and scattering [37,38].…”
