Abstract:
This article summarizes the ongoing studies on the photo-hydrogen-evolving molecular devices (PHEMDs) made up of polypyridyl Ru(II) photosensitizers and Pt(II)-based molecular catalysts, carried out in the authors' group in the last two decades. The H(2)-evolving activities of Pt(II)-based molecular catalysts demonstrated by various experimental evidences are first described. Then the structure-activity relationship, some important factors required for the higher catalytic activity, and several important insights into the mechanism of photochemical H(2) evolution catalyzed by the Ru(II)Pt(II)-based PHEMDs will be discussed in detail.

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.
