Unveiling dual catalysis enhancement of a pyridinium-containing Zn(ii) coordination polymer in aerobic photooxidation of organic substrates and selective photoreduction of CO₂

Abstract

We herein report two Zn(ii)–terpyridine coordination polymers for photoredox reactions.

Molecular Terpyridine–Lanthanide Complexes Modified Carbon Nitride for Enhanced Photocatalytic CO2 Reduction

“…The Carbon Capture, Utilization, and Storage project is recognized globally as one of the most effective method for reducing CO 2 . For CO 2 utilization, many studies have reported on the conversion of CO 2 into value-added chemicals. − Previous research studies have shown that photocatalytic CO 2 reduction reaction is a promising strategy for CO 2 utilization . The reaction has generally taken place at room temperature and under normal pressure with the aid of light and photocatalysts .…”

“…3−6 Previous research studies have shown that photocatalytic CO 2 reduction reaction is a promising strategy for CO 2 utilization. 7 The reaction has generally taken place at room temperature and under normal pressure with the aid of light and photocatalysts. 8 Molecule CO 2 has a stable linear nonpolar molecular structure(ΔG f,CO 0 = −394.228 kJ/mol) and is difficult to be activated.…”

“…They can coordinate with many kinds of N -containing ligands, such as polypyridyl ligands. For example, lanthanide ions coordinate with terpyridine-based ligands to form multifunctional complexes, which have intriguing applications in gas storage, magnetism, and luminescence. − Recently, we reported terpyridine-based metal complexes for efficient photocatalytic CO 2 reduction. ,, Inspired by these previous studies, we became interested in the catalytic performances of REE-based complexes in photocatalytic CO 2 reduction, preparing and investigating hybrid catalysts based on lanthanide complexes and CN.…”
