Microwave‐Assisted Rapid Substitution of Ti for Zr to Produce Bimetallic (Zr/Ti)UiO‐66‐NH₂ with Congenetic “Shell–Core” Structure for Enhancing Photocatalytic Removal of Nitric Oxide

Small, Journal Year: 2023, Volume and Issue: 19(20)

Published: Feb. 17, 2023

Abstract Efficient nitric oxide (NO) removal without nitrogen dioxide (NO 2 ) emission is desired for the control of air pollution. Herein, a series (Zr/Ti)UiO‐66‐NH with congenetic shell–core structure, denoted as Ti‐UION, are rapidly synthesized by microwave‐assisted post‐synthetic modification NO removal. The optimal Ti‐UION (i.e., 2.5Ti‐UION) exhibits highest activity 80.74% moisture, which 21.65% greater than that UiO‐66‐NH . efficiency 2.5Ti‐UION further increases to 95.92% photocatalyst deactivation under an anhydrous condition. This because selectively produced in photocatalysis completely adsorbed into micropores, refreshing active sites subsequent reaction. In addition, enhanced photocatalytic after Ti substitution due presence electron acceptor, potential difference between shell and core crystal, high conductivity TiO units. Additionally, improved adsorption gas molecules not only favors oxidation, but also avoids work provides feasible strategy rapid metal metal‐organic frameworks insights photodegradation.
