<p><span style=color: rgba(23 43 77 1)>This Special Issue is dedicated to transition-metal-containing bifunctional catalysts their design and catalytic applications. Transition-metal-catalyzed reactions are highly demanded in modern chemical industry. Nanosized mono- and bimetallic particles as well as complexes of transition metals are well known as catalysts for many processes such as hydrogenation oxidation deoxygenation carbonylation cross-coupling etc. The search for novel supports is of high importance and the optimization of catalysts' morphology and functionalities is a constantly developing field. The Special Issue is focused on bifunctional catalysts which is an emerging field of catalysis including a variety of systems: bimetallic magnetically separable inorganic (oxidic and carbonaceous) and polymeric systems.</span></p>
