“…Screening of different light sources showed that blue light slightly increased the yield. The apparent quantum efficiency (AQE) was 0.54 % at 450 nm (see the Supporting Information) [40c] . Furthermore, increasing or decreasing the loading amounts of catalyst did not improve the yield (Table 1, entries 20 and 21).…”

Am agnetic CdS quantum dot(Fe 3 O 4 /polydopamine (PDA)/CdS) was synthesized through af acile and convenient method from inexpensives tarting materials. Characterization of the prepared catalyst was performedb ym eans of FTIR spectroscopy,X RD, SEM, TEM, energy-dispersive Xray spectroscopy, and vibrating-samplem agnetometert ech-niques. Fe 3 O 4 /PDA/CdS was found to be ah ighly active photocatalyst for the amidation of aromatic aldehydes by using air as ac lean oxidantu nder mild conditions. The photocatalyst can be recovered by magnetic separation and successfully reused for five cycles without considerable loss of its catalytic activity.

Artificial photosynthesis has attracted increasing attention due to recent environmental and energy concerns. Metal halide perovskites (MHPs) demonstrating excellent optoelectronic properties have currently emerged as novel and efficient photocatalytic materials. Herein, the structural features of MHPs that are responsible for the photoinduced charge separation and charge migration properties are briefly introduced, and then important and necessary photophysical and photochemical aspects of MHPs related to photoredox catalysis are summarized. Subsequently, the applications of MHPs for solar energy harvesting and photocatalytic conversion, including H2 evolution, CO2 reduction, degradation of organic pollutants, and photoredox organic synthesis, are extensively demonstrated, with a focus on strategies for improving the performance (e.g., selectivity, activity, stability, recyclability, and environmental compatibility) of these MHP‐based photocatalytic systems. To conclude, existing challenges and prospects on the future development of MHP‐based materials towards photoredox catalysis applications are detailed.

“…[82]. Copyright 2020 Elsevier photocatalyst, is applied to the transformation of BA to H 2 and BAD under Vis-NIR light irradiation [76]. The results show that the Au-Pt@CdS composite exhibits higher production of H 2 and BAD than CdS deposited Au nanorods (Au@ CdS) and CdS deposited Pt-covered Au nanorods (Au@ Pt@CdS), indicating that the spatial distribution of metal components and the composition of bimetal-semiconductor composites affect photocatalytic activity.…”

The conversion of biomass into valuable chemicals has promise for application in biorefineries. Light-driven photoredox catalysis, with the typical features of green route and operation under mild conditions, is considered a promising strategy for renewable biomass or biomass-derived intermediates conversion into high-value-added chemical feedstocks. In this review, we strongly emphasize the recent advances in photocatalytic valorization of lignin model compounds and biomass-derived alcohols. We briefly summarize the advances in photocatalytic cleavage of the β-O-4 bond or C–C bond into usable chemicals in the lignin model. On the other hand, we clarify not only the hybrid system for cooperative biomass-relevant alcohols oxidation and hydrogen (H2) evolution but also the tunable accessibility to variation of the target products from the same alcohol reactant by catalyst design and optimization of reaction conditions. It is hoped that this review will inspire the rational design of photoredox catalysis-based systems toward efficient biomass-derived platform molecules valorization to obtain target-oriented valuable products.
