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

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