Solar-responsive triple photocatalytic action of sulfur-bridged-2DRB framework composites for selective 1,4-NADH regeneration with simultaneous benzyl alcohol production and boronic acid conversion

Abstract

The fixation of nicotinamide adenine dinucleotide (NAD⁺), boronic acid (BA) and aromatic aldehyde for the production of solar chemicals is gaining increasing importance due to its worldwide industrial importance. To achieve this, we herein report the synthesis and development of a highly efficient solar-responsive sulfur-bridged-two-dimensional rose bengal (SB-2DRB) framework composite via a thermal condensation technique. The composite photocatalyst/biocatalyst system using SB-2DRB functions in a highly efficient manner, leading to high NADH regeneration (62.54%), followed by its consumption in exclusive benzyl alcohol production (166.7 µL) from benzaldehyde, along with the synthesis of phenol (96%). The present research endeavour highlights the development and application of a sulfur-based photocatalyst for value-added direct solar fuel formation under solar light.
