  1. Applications of metal-organic frameworks in adsorption/separation processes via hydrogen bonding interactions

URL:

Metal–organic frameworks (MOFs) are promising environmental remediation materials due to their ability to adsorb a diverse range of pollutants. Many comparatively inert materials can still adsorb onto MOFs through hydrogen bonding. Pursuing research on the hydrogen bonding interactions of MOFs and pollutants is sure to provide effective solutions for preserving the environment.

  1. Z-scheme CdS/g-C3N4 composites with RGO as an electron mediator for efficient photocatalytic H2 production and pollutant degradation

URL:

Z-scheme photocatalytic systems offer attractive options for pollutant degradation, hydrogen fuel generation, and carbon dioxide reduction. Now, researchers from KNU have developed a novel Z-scheme photocatalyst using cadmium sulfide (CdS), reduced graphene oxide and graphitic carbon nitride?(g-C3N4) that offers improved charge separation and long-term photostability.

  1. Influence of TiO2 morphology on the photocatalytic efficiency of direct Z-scheme g-C3N4/TiO2 photocatalysts for isoniazid degradation

URL:

Titanium dioxide (TiO2) is an important catalyst for the degradation of pharmaceuticals and dyes, but its use is limited by its high electron band gap and poor photocatalytic activity. In this study, researchers not only fabricate a new Z-scheme graphitic carbon nitride/TiO2 photocatalyst, but also propose a mechanism to enhance the photocatalytic ability of TiO2 ??photocatalysts through Z-scheme charge transfer processes.

  1. Adsorption of diclofenac sodium from water using oxidized activated carbon

URL:

Even trace amounts of pharmaceutical and personal care products in water can harm aquatic life and wreak havoc on the environment. There is an increasingly urgent need to develop effective and inexpensive materials that can adsorb these pollutants from water. Oxidized activated carbons (OACs)—surface-modified activated carbons—are one such group of materials with a facile synthesis and high adsorptive capacity.

  1. Adsorptive removal of 2,4-dichlorophenoxyacetic acid (2,4-D) from water with a metal–organic framework

URL:

2,4-dichlorophenoxyacetic acid (2,4-D) is a highly carcinogenic herbicide. But despite its dangerous effects, it is still widely used. Metal–organic frameworks (MOFs) are a promising option for the removal of toxic herbicides from contaminated water. Here, scientists evaluate how an MOF, called MIL-53, can be used to remove 2,4-D from wastewater.
