The oxygen reduction reaction (ORR) is central to energy devices and sustainable chemical production. While acidic and alkaline ORR systems are well studied, neutral media offer advantages such as biocompatibility, environmental safety, and material stability, yet remain less explored. This mini-review summarizes recent progress in ORR electrocatalysis under neutral conditions, covering both four-electron (4e-) and two-electron (2e-) pathways. Emphasis is placed on catalyst design strategies and performance in complex environments like seawater. Key challenges and future directions are also discussed to guide the development of efficient and scalable ORR systems for real-world applications.

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...
