Au-nanorod-modified PCN-222(Cu) for H2 evolution from HCOOH dehydrogenation by photothermally enhanced photocatalysis.

Abstract

Formic acid molecules, which can be produced by reducing CO2, are considered to be liquid organic hydrogen carriers. Herein, PCN-222(Cu) loaded with Au nanorods was prepared via following a seed-induced growth route, and it exhibited highly selective photocatalytic performance during H2 generation (rate: 2.33 ± 0.12 mmol g-1 h-1, QY: 2.7 ± 0.14%) from HCOOH dehydrogenation, enhanced by plasmonic Au.
