SACs are transforming CO2 conversion and energy applications due to their high catalytic efficiency, unique electronic structures, and maximal atom utilization. They have shown great promise in CO2 electroreduction, hydrogenation, and dry reforming, yet challenges remain in their synthesis, stability, and scalable production. This review explores advances in SAC design, support interactions, and electronic tuning to enhance catalytic performance. It also analyzed state-of-the-art characterization techniques used to probe SAC structures and reaction mechanisms. Machine learning is emerging as a powerful tool for predicting SAC stability and optimizing reaction pathways. By examining recent breakthroughs and existing limitations, this work provides insights into the future of SACs in energy applications and CO2 utilization, highlighting their role in sustainable chemical transformations and carbon-neutral technologies.

Reduction of Alkenes: Catalytic Hydrogenation
Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.

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...
