Carboxylation Transition metal ‐ promoted carboxylation of various organic compounds has attracted much attention, and various types of reactions have been reported. In their Full Paper on page   1170   ff., which is featured on the Back Cover, Nozomi Saito, Zhongdong Sun, and Yoshihiro Sato report on the nickel(0) ‐ promoted carboxylation of aryl ynol ether that proceed in a highly regioselective manner to produce α ‐ substituted β ‐ aryloxyacrylic acid derivatives. Such derivatives could be transformed into the corresponding optically active β ‐ aryloxypropionic acid derivatives via rhodium ‐ catalyzed asymmetric hydrogenation. [ABSTRACT FROM AUTHOR]

The electrochemical reduction of CO2 The cover picture shows MoS2 and Ni‐doped MoS2 catalysts, and the reaction path of CO2 electrochemical reduction to CH4 on Ni‐doped MoS2. In their Full Paper on p. 1899 ff., J. K. Nørskov and co‐workers describe how their density functional theory calculations predict MoS2, MoSe2, and Ni‐doped MoS2 to have significantly improved activity for CO2 electrochemical reduction over the best transition metal catalysts. This activity arises from the binding of intermediates to different sites, which allows for deviations from the scaling relations between the intermediates on transition metals. Their results point to the broader application of the active edge sites of transition metal dichalcogenides in complex electrochemical processes. [ABSTRACT FROM AUTHOR]

It is highly desired to achieve controllable product selectivity in CO2 hydrogenation. Herein, we report light‐induced switching of reaction pathways of CO2 hydrogenation towards CH3OH production over actomically dispersed Co decorated Pt@UiO‐66‐NH2. CO, being the main product in the reverse water gas shift (RWGS) pathway under thermocatalysis condition, is switched to CH3OH via the formate pathway with the assistance of light irradiation. Impressively, the space‐time yield of CH3OH in photo‐assisted thermocatalysis (1916.3 μmol gcat−1 h−1) is about 7.8 times higher than that without light at 240 °C and 1.5 MPa. Mechanism investigation indicates that upon light irradiation, excited UiO‐66‐NH2 can transfer electrons to Pt nanoparticles and Co sites, which can efficiently catalyze the critical elementary steps (i.e. CO2‐to‐*HCOO conversion), thus suppressing the RWGS pathway to achieve a high CH3OH selectivity.
