Efficiently generating C1 building blocks from environmentally friendly carbon sources, such as through photocatalytic CO2 reduction, is essential for fostering a sustainable circular economy. The pursuit of mild catalytic activation methods has yielded powerful catalysts that can be synergistically employed alongside various reaction media to enhance overall performance. Herein, we elucidate the influence of diverse imidazolium‐based ionic liquids as additives for visible‐light‐driven CO2 reduction with ruthenium(II)‐ and rhenium(I)‐bipyridine complexes. Our investigation reveals that incorporating ionic liquids into traditional solvents at concentrations below 10 % can markedly boost CO production while suppressing H2 generation. The best results were obtained for the highly basic ionic liquid [C2mim][OAc], resulting in a substantial rise in CO formation from 0.3 μmol/h to 5.4 μmol/h and an increase in turnover number from 3 to 59. This study underscores the cooperative influence of imidazolium‐based ionic liquids on CO2 photoreduction while circumventing their use as primary solvents, thus offering a promising avenue for sustainable chemical synthesis.

This study utilizes Social Information Processing (SIP) theory to investigate the relationship between organizational preventive actions (substantive vs. symbolic), employee preventive behavior, the mediating role of conspiracy beliefs, and moderating role of leadership integrity in the context of Covid‐19. The study explains leadership integrity as a boundary condition to facilitate or hinder the mediated relationship between organizational actions and employee preventive behavior (EPB). The hypothesized model was tested using partial least square structural equation modeling (PLS‐SEM) on two‐wave data collected from 281 respondents. The results revealed that substantive actions do not predict EPB directly but through conspiracy beliefs. Contrary to these, symbolic actions negatively predict EPB directly. Leadership integrity moderates the relationship between substantive actions and conspiracy beliefs, while the interaction effect with symbolic actions is not supported. The findings of this study caution managers to walk their talk because employees critically observe the most apparent actions, especially when management fails to practice them. The study contributes to social information processing theory by pointing to leadership integrity as a source of authenticity to curb the negative impact of symbolic actions and catalyst the effect of substantive actions on employee preventive behavior.
