Au-nanorod-modified PCN-222(Cu) for H 2 evolution from HCOOH dehydrogenation by photothermally enhanced photocatalysis.

Formic acid molecules, which can be produced by reducing CO 2 , 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 H 2 generation (rate: 2.33 ± 0.12 mmol g -1 h -1 , QY: 2.7 ± 0.14%) from HCOOH dehydrogenation, enhanced by plasmonic Au.
