Cu-Ag interactions in bimetallic Cu-Ag catalysts enhance C product formation during electrochemical CO reduction.

The electroreduction of CO (CORR) is a promising alternative to the direct CO electroreduction reaction (CO2RR) to produce C products. Cu-based electrocatalysts enable the formation of C-C bonds, leading to various C hydrocarbon and oxygenate products. Herein, we investigated how the composition of bimetallic Cu-Ag catalysts impacted the nature of the Cu-Ag interactions and the product distribution of the CORR, aiming to improve the selectivity to C products.

Isolating Al Surface Sites in Amorphous Silica-Alumina by Homogeneous Deposition of Al on SiO Nanoparticles.

Well-defined amorphous silica-alumina (ASA) with a relatively low Al loading were synthesized by homogeneous deposition-precipitation of Al on SiO nanoparticles to understand the nature and formation of Brønsted acid sites (BAS). The amount of Al grafted relative to the silanol density was varied by variation of the size of SiO nanoparticles, reflected by their surface areas between 90 and 380 m·g. Two sets of ASA were synthesized, one aiming at a SiOH/Al ratio of 3, corresponding to the maximum amount of BAS represented by Al perturbation of SiOH groups, and the second one aimed at studying the impact of Al dispersion by using a constant Al loading (Si/Al ≈ 103).

Ce Promotion of InO for Electrochemical Reduction of CO to Formate.

InO is a promising electrocatalyst for CO electroreduction (COER) to formate. InO nanoparticles doped with Pd, Ni, Co, Zr, and Ce promoters using flame-spray pyrolysis were characterized and evaluated in a gas diffusion electrode for the COER. Doping results in slight shifts of the In binding energy as probed by XPS, which correlates with a change of the Faradaic efficiency to formate (FE) in the order Ce-doped InO > Zr-doped InO > InO > Pd-doped InO > Ni-doped InO > Co-doped InO.

Transferable, Living Data Sets for Predicting Global Minimum Energy Nanocluster Geometries.

Modeling of nanocluster geometries is essential for studying the dependence of catalytic activity on the available active sites. In heterogeneous catalysis, the interfacial interaction of the support with the metal can result in modification of the structural and electronic properties of the clusters. To tackle the study of a diverse array of cluster shapes, data-driven methodologies are essential to circumvent prohibitive computational costs.

Unravelling CO Activation on Flat and Stepped Co Surfaces: A Molecular Orbital Analysis.

Structure sensitivity in heterogeneous catalysis dictates the overall activity and selectivity of a catalyst whose origins lie in the atomic configurations of the active sites. We explored the influence of the active site geometry on the dissociation activity of CO by investigating the electronic structure of CO adsorbed on 12 different Co sites and correlating its electronic structure features to the corresponding C-O dissociation barrier. By including the electronic structure analyses of CO adsorbed on step-edge sites, we expand upon the current models that primarily pertain to flat sites.

A multicentric European survey about this topic was conducted focusing on safety issues, and the results were compared with the current literature.

-Linked Metastatic Paraganglioma: A Case Report with Implications for Counseling and Follow-Up of Pathogenic Variant Carriers.

Head and neck paragangliomas are slow growing and highly vascular neuroendocrine tumors. It is currently assumed that variants exclusively cause benign and often multicentric head and neck paragangliomas. Here, we present a patient diagnosed with multiple -linked head and neck paragangliomas who in addition developed paraganglioma metastases to the lung and spine and a primary or metastatic paraganglioma in the head of the pancreas.

Descriptor for CN-Supported Single-Cluster Catalysts in Bifunctional Oxygen Evolution and Reduction Reactions.

Developing highly active cluster catalysts for the bifunctional oxygen evolution reaction (OER) and oxygen reduction reaction (ORR) is significant for future renewable energy technology. Here, we employ first-principles calculations combined with a genetic algorithm to explore the activity trends of transition metal clusters supported on CN. Our results indicate that the supported clusters, as bifunctional catalysts for the OER and the ORR, may outperform single-atom catalysts.

Al promoted the methanol yield, with an optimum being observed at an Al content of 5 mol %.

Improving the performance of ASA in the DAC of 2,5-DMF and ethylene.

A variety of methods are employed to synthesize amorphous silica-alumina (ASA) to resolve the role of Al speciation and surface area in the catalytic performance in the Diels-Alder cycloaddition reaction of 2,5-dimethylfuran and ethylene to -xylene. ASA was prepared by homogeneous deposition-precipitation (HDP) of Al on ordered mesoporous silica, , SBA-15 and OMS prepared under hydrothermal synthesis conditions using an imidazole-based template, and one-step flame spray pyrolysis (FSP). IR spectroscopy and Al MAS NMR showed that the resulting ASA represented a set of materials with distinct textural and acidic properties.

Structure Sensitivity of CO Hydrogenation on Ni Revisited.

Despite the large number of studies on the catalytic hydrogenation of CO to CO and hydrocarbons by metal nanoparticles, the nature of the active sites and the reaction mechanism have remained unresolved. This hampers the development of effective catalysts relevant to energy storage. By investigating the structure sensitivity of CO hydrogenation on a set of silica-supported Ni nanoparticle catalysts (2-12 nm), we found that the active sites responsible for the conversion of CO to CO are different from those for the subsequent hydrogenation of CO to CH.
