Solar-Responsive Treble 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 worldwide industrial importance. As a means to achieve this, we herein report on the synthesis and development highly efficient solar-responsive sulfur-bridged-two-dimensional Rose Bengal (SB-2DRB) framework composite via the thermal condensation technique. The composite photocatalyst/biocatalyst system using SB-2DRB as 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.
