The hydroformylation of alkenes is a cornerstone transformation for the chemical industry, central both functionalizing and extending carbon backbone an alkene. In this study, silica‐supported crystalline rhodium sulfide nanoparticles are explored as heterogeneous catalysts in reactions, it found that Rh x S y systems ( = 17, 15 or 2, 3 with 1 wt% on SiO 2 ) greatly outperform metallic nanoparticles. These prove to be exceptionally competitive when benchmarked against other cutting‐edge terms activity, 17 /SiO being superior catalyst candidate. By employing local environment descriptors, unsupervised machine learning density functional theory, structure‐performance relationships examined. results highlight presence close proximity catalytic site unlocks tunability surface properties. This allows substrate affinity modulated, particular , adsorption energies rivalling those pristine improved spatial resolution.

Incorporating phosphorus (P) into the active metals of a catalyst is an effective strategy to enhance catalytic performance. However, mechanisms underlying influence introduced species on performance remain largely unknown. Herein, we observe pronounced shift in product selectivity CO2 hydrogenation from CH4 CO upon introducing P Ru/SiO2 catalysts. This alteration attributed role as "fence" hindering migration H species. The adsorbed CO, key intermediate for methanation, preferentially desorbed before cross further hydrogenation, thereby weakening H2-assisted activation process and consequently inhibiting generation. Our findings provide in-depth insights origin phosphorization-induced modulation hydrogenation. Furthermore, concept "fence effect" opens promising avenue design various industrial processes.

Abstract Inexpensive iron‐based materials are considered promising electrocatalysts for nitrate (NO 3 − ) reduction, but their catalytic activity and spontaneous corrosion remain challenges. Here, the α‐Fe 2 O active surface is reconstructed by gradient phosphorization to obtain FeP x with higher electrochemical activity. 2.0 optimizes adsorption energy of NO its reduction intermediates, meanwhile promote generation hydrogen ( * H) inhibit H . More importantly, Fe P can serve as binding sites H, respectively, which improves electron utilization deoxygenation efficiency subsequent hydrogenation selective synthesis NH 91.7% conversion rate achieved 100 mL 200 mg L −1 −N, 99.3% ammonia (NH selectivity (yield 1.79 h cm −2 ), 91.4% Faraday in h.

ABSTRACT Ruthenium (Ru)‐based electrocatalysts show great promise as substitutes for platinum (Pt) the alkaline hydrogen evolution reaction (HER) because of their efficient water dissociation capabilities. Nevertheless, strong adsorption Ru–OH intermediates (Ru‐OH ad ) blocks active site, leading to unsatisfactory HER performance. In this study, we report a universal ligand‐exchange strategy synthesizing MOF‐on‐MOF‐derived FeP–CoP heterostructure‐anchored Ru single‐atom site catalyst (Ru‐FeP‐CoP/NPC). The obtained shows low overpotential (28 mV at 10 mA cm −2 and high mass activity (9.29 A mg −1 100 mV), surpassing performance commercial Pt/C by factor 46. Theoretical studies that regulating local charge distribution sites could alleviate surrounding OH − blockages, accelerating facilitating adsorption/desorption, thus enhancing activity. This work aims inspire further design highly durable with tailored electronic properties high‐purity production.
