Calculation and Sharing of Regional Carbon Emission Reduction Considering Construction of Ultra High Voltage AC Projects

open access: yesZhongguo dianli
Under the "dual carbon" goal, the ultra-high voltage (UHV) AC project, with its advanced technological means, will play a greater role in consuming clean energy and reducing transmission losses. Considering that there is relatively little research on the

Kontrolle heterogener Katalyse mittels Unter‐Oberflächen‐Sauerstoff

open access: yesAngewandte Chemie, EarlyView.
Während der CO‐Oxidation auf Rhodiumoberflächen wird die Reaktionsdynamik in der Gegenwart von Unter‐Oberflächen‐Sauerstoff (Osub) deutlich verändert. Unter‐Oberflächen‐Sauerstoff stabilisiert vorübergehend durch Oberflächenreaktionen gebildetes physisorbiertes CO2, was diesem ermöglicht, vorübergehend zu binden und mit der Oberfläche zu thermalisieren.

From Surfaces to Interfaces: Ambient Pressure XPS and Beyond [PDF]

open access: yes, 2018
The rapidly increasing field of surfaces under ambient conditions of temperature, and pressure in gas and liquid environments, reflects the importance of understanding surface properties in conditions closer to practical situations. This has been enabled

Controlling Heterogeneous Catalysis With Subsurface Oxygen

open access: yesAngewandte Chemie International Edition, EarlyView.
During CO oxidation on rhodium surfaces, the reaction dynamics are markedly altered in the presence of subsurface oxygen. Subsurface oxygen stabilizes the nascent physisorbed CO2 formed after the surface reaction, allowing it to become transiently trapped and thermalize with the surface.

Surface Properties of CeB6 and Challenges in Surface Preparation Revealed by Scanning Tunneling Microscopy

open access: yesAdvanced Physics Research, EarlyView.
The investigation of the Kondo lattice system CeB6${\rm CeB}_6$ by highly surface sensitive techniques is hampered by difficulties in preparing well‐ordered, atomically flat surfaces. The richness of possible surface terminations and their impact on spectroscopic STM results are discussed.

Eco‐Friendly Synthesis of Cobalt Phthalocyanine for High‐Efficiency CO2${\rm CO}_{2}$ Electroreduction

open access: yesChemistry – A European Journal, EarlyView.
A sustainable synthesis of cobalt phthalocyanine (CoPc) using low‐impact solvents yields high‐performance electrocatalysts with reduced waste (E‐factor 18.6). When integrated into gas diffusion electrodes, CoPc achieves up to 12% Faradays efficiency for CO2‐to‐methanol and 65% CO2‐to‐CO conversion, aligning with state‐of‐the‐art materials and enabling ...

Probing Radical‐Induced Magnetic Moment Modulation at Cobalt Interfaces via Soft X‐Ray Photoelectron Spectroscopy

open access: yesChemistry – A European Journal, EarlyView.
X‐ray photoelectron spectroscopy reveals to be a powerful technique to explore subtle changes of the electronic structure at the radical/cobalt interface. The radical chemisorption influences the cobalt electronic structure and consequently its magnetic properties.
