Mesoporous Materials as Catalyst support for Wastewater Treatment

Abstract

The scarcity of water resources has stimulated the exploration of sewage treatment technique. On account of flexible separation and recycling, heterogeneous catalysis has aroused strong interest among researchers. In terms of the specific surface area, pore dimension and catalytic sites distribution, porous materials hold infinite potentials in heterogeneous catalysis. Among different porous materials, mesoporous material is most favorable in aqueous system. Moderate diffusion flux and highly efficient mass transfer are achievable due to their appropriate pore dimension, high specific surface area and good organic adsorption capacity. Moreover, most kinds of mesoporous materials are non-toxic, environmental-friendly and highly stable in both acidic and basic conditions. In this review, several kinds of mesoporous materials (such as siliceous mesoporous materials, carbonaceous mesoporous materials and metallic mesoporous materials) are introduced involving their characteristics, advantages, disadvantages as well as their application in wastewater treatment.

Highly Mesoporous g-C3N4 with Uniform Pore Size Distribution via the Template-Free Method to Enhanced Solar-Driven Tetracycline Degradation

“…This is because GCN-500 is highly mesoporous, which is rich in active sites. It was found that the mesoporous property is also good in organic adsorption [ 42 ] and this helps to promote better photocatalytic performance. This is because once the pollutant adsorbs on the photocatalyst surface, photocatalysis can only take place.…”

“…In addition, supports drastically affect the catalytic properties of supported nanoparticles. Mesoporous materials with a large surface area used as catalyst supports make a critical difference to a better dispersion of active phase, preventing the particles aggregation, and, therefore, can improve the activity and reusability of the catalysts 8,9 . Interaction with the support material can also considerably affect the activity and selectivity of noble metals nanoparticles in various reactions including hydrogenation 10,11 …”
