Figure 2a shows the CO2 conversion, MeOH selectivity/yield and TOF value of methanol formation as a function of the ZnO particle size. The detailed data on the physicochemical and catalytic properties of different samples (e.g., diameter of Cu (dCu), specific surface area of Cu (SCu) and...
However, there are two reaction pathways on the Cu surface: the inner-sphere reaction produces FA, and the outer-sphere reaction produces hydrofuroin [12]. Thus, the selectivity of Cu-based electrocatalysts needs to be improved and the electrochemical mechanism should be unveiled. Nanostructures ...
To prevent the Cu atoms from agglomeration or aggregation, surface capping ligand is critical as the stabilizing agent to allow Cu atoms to form a certain small core but not into a bulky core or an agglomerate. Furthermore, the ligand can significantly affect the physical and chemical properties...
The application of surface complexation models (SCMs) to natural sediments and soils is hindered by a lack of consistent models and data for large suites of metals and minerals of interest. Furthermore, the surface complexation approach has mostly been developed and tested for single solid systems...
The structure, morphology, microstructure, specific surface area and electrochemical properties of the resultant particles were characterised by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, nitrogen physical adsorption, charge–discharge test and cyclic voltammetry (CV) ...
research direction about different morphologies Cu2O are summarized and pointed out.Two main trends for Cu2O morphology research are pre-sented,one is about unconventional polyhedra with more crystal planes,the other is about nanoframes and nanocages with bigger specific surface area and higher opening ...
process were carefully optimized. Finally, a flexible CuNa-CF catalyst membrane was successfully obtained (Supplementary Fig.1). As shown in Supplementary Fig.2a, the Brunauer-Emmett-Teller (BET) specific surface area of the as-prepared CuNa-CF catalyst membrane is 597.31 m²/g, and the ...

To improve the adsorption properties of the casein with functional group-rich, we hydrolyzed it into casein peptides (CPs) to increase its specific surface area. As shown in the Scheme 1, after sufficient interaction and adsorption of CPs with Cu2+ in solution, the Cu2+ were reduced to Cu...
