Three-dimensional photocatalysts with a network structure

Abstract

The synthetic strategies and energy and environmental applications of 3D network photocatalysts are summarized and the ongoing challenges and perspectives are highlighted.

Oxygen-doped carbon nitride aerogel: A self-supported photocatalyst for solar-to-chemical energy conversion

“…So far, CNs with various morphologies from 0D, 1D, 2D to 3D have been designed [8] , among which carbon nitride aerogel (CNA) or hydrogel (CNH) with 3D hierarchical structure are one of the most outstanding candidates thanks to their interconnected open-framework that could expose more reactive sites, provide convenient mass transfer channels and then promote the surface chemical reaction. Aiming at this goal, different strategies have been presented.…”

Visible-light photooxidation in water by 1O2-generating supramolecular hydrogels

“…Catalytic supramolecular hydrogels provide a promising solution to this challenge. [15][16][17][18][19] Hydrogel networks can address the solubility problem because hydrophobic aromatic compounds oen associate into the nanober network in water and become reactively accessible. 20 For example, the Meijer 21 and Escuder 22 groups have shown that a self-assembled, 1D ber network enhances catalytic activity compared to its non-assembled counterpart.…”

Advanced Design and Synthesis of Composite Photocatalysts for the Remediation of Wastewater: A Review

“…In recent years, there have been a great number of works reporting a new generation of composite photocatalysts with 3D frameworks [115]. Actually, the 3D photocatalysts with well-deigned frameworks show great advantages such as a large specific surface area, high adsorptive capacity, good structure stability, good mass transfer ability, and a large number of exposed active sites, which make them promising candidates for the highly efficient photodegradation of contaminants in water.…”
