Promoting the formation of metal–carboxylate coordination to modulate the dimensionality of ultrastable lead halide hybrids

Abstract

In this study, we employ the synthetic strategy involving coordination chemistry to rationally modulate the dimensionality of lead halide hybrids, realizing the transition from 2D to 3D structures.

Isoreticular Azobenzene Functionalization of Ultrastable Lead Chloride Hybrids for Enhanced Photocatalytic Aerobic Oxidation

“…By employing p -benzoquinone ( p -BQ) as a •O 2 – scavenger, K 2 S 2 O 8 as an electron ( e – ) scavenger, and (NH 4 ) 2 C 2 O 4 as a hole ( h + ) scavenger, the overall photocatalytic evolution rates of TMOF-6-4azo decreased to 383.5 μmol g –1 h –1 , 606.9 μmol g –1 h –1 , and 410.7 μmol g –1 h –1 , respectively, suggesting the important roles of light-generated e – , h + and superoxide radical anion •O 2 – in photocatalytic mechanism (Figure d). Therefore, based on literature reports and the above-mentioned studies, the mechanism of photocatalytic ethylbenzene oxidation was proposed in Figure c. ,− Initially, the lead chloride MOF was photoexcited to generate e – - h + pairs. Ethylbenzene and O 2 were simultaneously adsorbed on the MOF surfaces, where ethylbenzene was oxidized to •R by holes and O 2 was reduced to •O 2 – via electrons.…”
