Summary: Atomically dispersed Pt species supported on Fe2O3 (Pt1/Fe2O3) are successfully constructed via a simple ball milling process. Pt1/Fe2O3 exhibits excellent selectivity and conversion rate in the selective hydrogenation of cinnamaldehyde (CAL) in pure water medium, attributed to its superior dissociation ability of H-2 and preferential adsorption of CAL via C=O.

Summary: An iridium complex-catalyzed reductive etherification of alpha,beta-unsaturated ketones and aldehydes with primary alcohols has been demonstrated, resulting in the formation of allyl ethers with excellent yields. Deuterated and control experiments revealed that this etherification transformation proceeds through a cascade transfer hydrogenation and alcohol condensation process. Furthermore, the feasibility of this protocol has been confirmed through gram-scale experiments.

Summary: Hydroboration of amides using the supported lanthanum benzyl material La(CH2C6H4NMe2-o)(3)@SBA-15 is highly active and selective, demonstrating good tolerance for various functional groups and heteroatoms. The reduction procedure showed recyclable and reusable properties of heterogeneous catalysts, and is applicable to gram-scale synthesis. It represents the first example of hydroborative reduction of amides to amines mediated by heterogeneous catalysts.

Summary: The study presents a scalable and economically feasible approach to prepare atomically dispersed Pd sites on titanium substituted ordered mesoporous silica for catalytic combustion. The catalyst exhibits excellent catalytic activity towards cyclohexane, n-hexane, and styrene combustion, maintaining 100% mineralization. The outstanding catalytic performance is attributed to the considerable amount of acid sites derived from Ti substitution and the maximized Pd utilization realized by atomic Pd sites.

Summary: In this study, a Ru-immobilized bisphosphine-based porous organic polymer (Ru@PP-POP) was used as an efficient heterogeneous catalyst for the chemoselective hydrogenation of cinnamaldehyde to cinnamyl alcohol with high chemoselectivity (98%) and excellent recyclability. The catalyst showed a high turnover number (970) and a high turnover frequency (240h^-1), representing the best activity obtained using a phosphine-based heterogeneous Ru-catalyst in this transformation.

Summary: The determination of catalytically active sites is crucial for the design of efficient and stable catalysts. A structurally controllable catalyst system (Pd/SBA-15) was developed to reveal the catalytic active sites for the selective hydrogenation of ketones. It was found that unsupported Pd nanocrystals showed no catalytic activity, while oxidized Pd species exhibited high catalytic activity. The catalytic activity decreased with the decreased oxidation state of Pd. This work provides insights not only into the hydrogenation mechanism of ketones but also other unsaturated compounds containing polar bonds.

Summary: The catalytic performance of a Cu2O-Fe3O4@TNT nanocatalyst derived from Fe(iii) acetylacetonate, Cu(ii) acetylacetonate and hydrogen titanate nanotubes (HTNTs) has been investigated for the first time for the click reaction in a water medium at room temperature. The nanocatalyst exhibited superior catalytic activity for the multicomponent synthesis of 1,2,3-triazoles in an aqueous medium and can be reused and recovered using an external magnet.
