The reverse water-gas shift (RWGS) reaction is one of the most promising strategies to bridge large-scale CO2 utilization with transitional syngas conversion processes. As promising materials for the RWGS reaction, Mo-based catalysts feature accessible raw materials and high activity. However, developing catalysts combining high activity, complete selectivity, and long-term stability poses major challenges. In this context, we provide a comprehensive and critical analysis of recent advances in Mo-based catalysts for the RWGS reaction. This review emphasizes the structure-performance relationships in various Mo-based catalysts, including promotional effects, metal-support interactions, and vacancy engineering that enable enhanced CO2 conversion, product selectivity, and long-term durability. We also address the ongoing debate surrounding the nature of active sites and elucidate their dynamic evolution, offering forward-looking perspectives on the rational design of improved Mo-based catalysts. Furthermore, we outline the fundamental reaction mechanisms, with emphasis on the role of advanced in situ/operando characterization techniques. By critically evaluating current challenges and future opportunities, this work aims to inspire innovations in RWGS technology and support the transition toward sustainable CO2 utilization for the production of synthetic chemicals and fuels.

Preparation of Alcohols via Addition Reactions
The acid-catalyzed addition of water to the double bond of alkenes is a large-scale industrial method used to synthesize low-molecular-weight alcohols. An acidic atmosphere is required to allow the hydrogen in the water molecule to act as an electrophile and attack the double bond in an alkene. The addition of a proton to the double bond creates a carbocation intermediate. The proton preferentially bonds to the less substituted end of the double bond to create a more stable carbocation...
Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
