“…GVL has attracted immense interest due to its ecotoxicity, biodegradability, low melting point, and high boiling point. Moreover, the efficiency of this system is comparable to the efficiency of other common solvents such as acetonitrile and dimethylformamide [86,87]. Due to its versatility, GVL has also been used as a biofuel and additive in the food industry [87,88].…”

Technological development made in the field of biomass application allows synthesizing several high-value products, such as furfuraldehyde. Furfural, produced through sequential hydrolysis and dehydration reactions from biomass, is considered a platform molecule and a precursor of several other chemicals and biofuels that are generated following reactions such as hydrogenation, hydrodeoxygenation, and decarboxylation. This review aims to reveal the environmental-friendly mechanisms followed for producing furfural derivatives and the design of catalysts and supports. Redox and acid-base properties of the molecules have been discussed. The stability, the details of the surface area, and the applications of the molecules to reduce the bottlenecks faced in the industrial production of bioproducts have been explored.

“…γ-Valerolactone (GVL) is considered a promising and versatile solvent because of its thermostable, non-toxic, and bio-derived characteristics while offering similar dielectric constant and polymer solubility to common dipolar aprotic solvents. 32 According to the toxicity and biodegradation data of GVL, it has low acute toxicity to aquatic organisms and is readily biodegraded in the natural environment. 31 Moreover, the low melting (−31 °C) and high boiling (207 °C) points of GVL also make it a safe solvent for application on a larger scale.…”

Solvents can significantly influence chemical reactions in condensed phases. Their critical properties are increasingly recognized in various research domains such as organic synthesis and biomass valorization. However, in semiconductor photocatalysis, solvents are primarily viewed as mediums for dissolving and diffusing substances, with their potential beneficial effects on photocatalytic conversions often overlooked. Additionally, common photocatalysis solvents like acetonitrile (ACN) pose serious safety and environmental concerns. In this study, we demonstrate that novel and safe green solvents, such as γ‐valerolactone (GVL), can significantly enhance the performance of semiconductor photocatalysis for C−H bond activation. Non‐specific solvent‐solute interactions are the primary contributors to increased photocatalytic activity in the self‐coupling of benzylic compounds. Specifically, GVL's large dielectric constant and high refractive index lower the energy barrier for the rate‐determining C−H bond activation step, facilitating a faster coupling reaction. The versatility of GVL is further demonstrated in reactions with multiple reagents and in various oxidation and reduction photocatalytic systems beyond classic C−H bond activation. This work not only pioneers the use of green solvents but also provides comprehensive insights for proper solvent selection in semiconductor photocatalysis.
