“…Furthermore, focusing on the recent advances in the electrochemical and photochemical CO 2 R with organohydrides metal-free catalysts, we mainly discuss two classes of organohydrides: pyridinium derivatives and benzimidazolines derivatives. For the more metal-free CO 2 R catalysts, we refer readers to several comprehensive reviews in the field. − Finally, we provide an outlook on future research directions, including the design of tailored organohydrides, the integration of in situ regeneration methods, and strategies for enhancing catalytic efficiency to unlock the full potential of organohydrides in the quest for efficient and environmentally benign CO 2 R processes.…”

The conversion of CO 2 into value-added chemicals and fuels using stable, cost-effective, and eco-friendly metal-free catalysts is a promising technology to mitigate the global environmental crisis. In the Calvin cycle of natural photosynthesis, CO 2 reduction (CO 2 R) is achieved using the cofactor NADPH as the reducing agent through 2e − /1H + or H − transfer. Consequently, inspired by NAD(P)H, a series of organohydrides with adjustable reducibility show remarkable potential for efficient metal-free CO 2 R. In this review, we first summarize the photosensitizers for NAD(P)H regeneration and list the representative photoenzyme CO 2 R system. Then, we introduce the NAD(P)H-inspired organohydrides and their applications in redox reactions. Furthermore, we discuss recent progress and breakthroughs by utilizing organohydrides as metal-free CO 2 R catalysts. Moreover, we delve into the reaction mechanisms and applications of these organohydrides, shedding light on their potential as sustainable alternatives to metal-based CO 2 R catalysts. Finally, we offer insights into the prospects and potential directions for advancing this intriguing avenue of organohydride-based catalysts for CO 2 R.
