Summary: Three kinds of porous organic polymers (POPs) containing N or P atoms were prepared and used as supports for Rh catalysts. The structures and compositions of these polymers were fully characterized. The Rh-N-POP showed a larger BET surface area and pore volume due to the bulk extrusion of triphenylphosphine (TPP) unit. The hydroformylation activity was promoted by the presence of free ligands in Rh-N-POP, but isomerization was greatly promoted by the TPP structure.

Summary: Metal-catalyzed hydroformylation of alkenes is widely employed for the synthesis of aldehydes, with rhodium being the most commonly used metal catalyst. However, due to rhodium's rarity, high cost, and depletion, finding alternative catalysts is of great interest. This review summarizes the recent advancements in hydroformylation using metals other than rhodium, highlighting cobalt as the only metal that poses a significant challenge to rhodium's dominance.

Summary: The authors develop a universal strategy to synthesize extra-heavy olefins through the sustained release of hydrogen and selective extraction of olefins. They achieve the selective production of C(12+)(=) from CO and water using Pt/Mo2N and Ru particles as catalysts in polyethylene glycol (PEG). PEG acts as a selective extraction agent to hinder hydrogenation of olefins. Under optimal conditions, the yield ratio of CO2 to hydrocarbons reaches the theoretical minimum, and the C(12+)(=) yield reaches its maximum with a selectivity of 40.4%.

Summary: Selective electrochemical reduction of CO to acetate can be achieved on an amino functionalized Cu surface. The Cu@NH2 catalyst shows significant catalytic performance with a CO-to-acetate Faradaic efficiency of 51.5% and an acetate partial current density of around 150 mA cm-2 at -0.75 V versus RHE. The amino groups on the Cu surface help maintain the low valence state of Cu and the H delta+ in the amino groups stabilize the oxygen-containing intermediates, promoting the formation of acetate through *CO-*CHO coupling.

Summary: In this study, PtFe/SiO2 catalyst was successfully prepared and showed excellent performance for non-oxidative propane dehydrogenation (PDH), efficiently producing propylene. The introduction of Fe component in the catalyst facilitated the high dispersion of Pt, preventing its agglomeration. Electron-rich Pt sites were formed in PtFe/SiO2, enhancing both propylene formation rate and mean lifetime. This work provides a pathway for developing robust Pt-based PDH catalysts through alloying with earth-abundant metals.

Summary: Electrosynthesis of valuable chemicals from CO2 or CO offers a promising approach to store renewable electricity and reduce carbon emission. In this study, amino functionalized Cu surface (Cu@NH2) derived from in situ electroreduction of copper ammonia chloride complexes exhibits significant catalytic performance for CO reduction to acetate. The amino groups on the Cu surface play a crucial role in maintaining the low valence state of Cu and stabilizing the oxygen-containing intermediates, thus promoting the coupling reaction between *CO and *CHO to form acetate.
