CO2 is a greenhouse gas and nontoxic, easily available renewable C1 feedstock. H2 clean cheap reductant that can be obtained from energy. Olefins are platform chemicals produced variety of raw materials such as petroleum, coal biomass. The production carboxylic acids by combining olefins, sustainable very promising protocol. However, only few advances in this topic have been achieved because novel catalysts need to developed. In work, we demonstrate simple iridium-based catalyst could efficiently promote the synthesis C2+ via reaction olefins with H2. was effectively accelerated catalytic system at 170 °C, which may applied various olefin substrates. mechanism studied through series control experiments. findings contribute advancing valuable products green chemicals.
