We developed a facile strategy to generate mesoporous N-doped carbon frameworks with tunable configurations and contents of N dopants, by using a secondary doping process via the treatment of a N,N-dimethylformamide (DMF) solvent. After the DMF treatment, the obtained N-doped carbon catalyst possesses a much increased density of pyridinic N and defects, which enhance the activation and adsorption of CO2 molecules, thus increasing the activity of CO2RR.

Well-defined PtPb nanocrystals (NCs) have been selectively synthesized via an effective method, and the optimized PtPb octahedra nanocrystals (ONCs)/C is the most active catalyst for the ethanol reforming to H2. X-ray photoelectron spectroscopy (XPS) reveals that the high Pt(0)/Pt(II) ratio in PtPb NCs/C enhances the alcohols reforming. The density functional theory (DFT) studies show the PtPb ONCs possess the highest surface averaged electronic occupation for unit Pt-atom, matching well with XPS results.

Liquid phase transmission electron microscopy (TEM) has a power to provide unique insight in nanoscale dynamic processes involving oxides nanomaterials, but material stability during imaging remains a challenge. Here we demonstrate that there is a correlation between oxide stability in LP-TEM and Gibbs free energy of hydration, which can aid in assessment of oxide suitability for LP-TEM.

A combined density functional theory (DFT) and scanning tunneling microscopy (STM) approach is used to predict the Fe-dopant distribution and clustering of Fe-doped CoO nanoisland. We find an anisotropic Fe-dopant incorporation pattern throughout the nanoisland with the most favorable Fe incorporation site at the oxygen edge and a change in Fe incorporation site preference upon clustering occurring at high Fe-dopant densities.
