Summary: In this study, uniformly porous and solid core porous particles were synthesized by aerosol spray pyrolysis route using a one-step process, which is of high interest for pharmaceutical and catalytic applications. The effect of synthesis parameters on the core size, surface area, and porosity of the core-shell structures was validated through morphological evaluation and nitrogen adsorption and desorption isotherms. Different surfactants (Brij-58, CTAB, P123) at various concentrations and combinations, as well as different core type compositions (NaCl, CeO2, and Ce0.8Zr0.2O2), were evaluated for the controlled synthesis of silica core-shell particles using a scalable synthesis method.

Summary: The oxidation performance of carbon monoxide (CO) is heavily influenced by the surface-active species and oxygen vacancies of nanocomposites. In this study, CuOx/Cu1.5Mn1.5O4 nanocomposites were fabricated via a solid-state strategy. It was found that the construction of CuOx/Cu1.5Mn1.5O4 nanocomposites led to the formation of abundant surface CuOx species and oxygen vacancies, resulting in significantly enhanced CO oxidation activity. The CO was completely converted to carbon dioxide (CO2) at 75 degrees Celsius when CuOx/Cu1.5Mn1.5O4 nanocomposites were used, surpassing the performance of individual CuOx, MnOx, and Cu1.5Mn1.5O4. Density functional theory (DFT) calculations further revealed that CO and O-2 exhibited relatively optimal adsorption energy on the surface of CuOx/Cu1.5Mn1.5O4, which was beneficial for CO oxidation activity. This work presents a promising method for preparing heterogeneous metal oxides with potential applications in catalysis.

Summary: In this study, oxidized coal liquefaction residue (OCLR) derived from solid waste was introduced into polyacrylonitrile (PAN)-based nanofibers to obtain activated reinforced porous carbon nanofibers (ARCNF) for efficient adsorption of organic dyes in wastewater. The effects of contact time, concentration, temperature, pH, and salinity on the adsorption capacity were examined. The adsorption processes of the dyes in ARCNF followed the pseudo-second-order kinetic model. The prepared ARCNF showed good regenerative performance and retained a high adsorption capacity even after multiple adsorption-desorption cycles.

Summary: The dissipation of energy in the form of heat causes a huge energy loss across the globe. Thermal insulation materials, such as silica aerogels, have great potential in alleviating the energy crisis due to their high surface area and low thermal conductivity. However, their mechanical fragility has limited their applications. In this study, silica-chitosan composite aerogels with different ratios were prepared and tested, and the results showed that the 1:1 ratio of sodium silicate aqueous solution and chitosan solution resulted in the best performance.

Summary: To promote the slow kinetics of alkaline electrolytes, it is necessary to develop an effective non-noble metal electrocatalyst. In this study, a self-sacrificing template method was developed to construct sandwich-like layered hollow structures CoP@NC (H-CoP@NC) for promoting hydrogen evolution kinetics. The hierarchical hollow nanostructures provide greater contact area between catalyst and electrolyte, shorten ion/electron transport distances, and expose more active sites. The introduction of nitrogen-doped carbon (NC) effectively prevents the aggregation of CoP and improves the electron transfer rate during phosphorylation. The overpotential of the catalyst H-CoP@NC is only 173 mV at a current density of 10 mA/cm2. The excellent catalytic activity can be attributed to the unique structure and the doping of heteroatom. This work provides a new method for designing hollow nanomaterials.

Summary: This study reports that Fe-doped CeO2 can be used as an effective catalyst for the synthesis of H2O2, exhibiting high 2e-ORR performance compared to pristine CeO2. The doping of Fe leads to lattice distortion and the formation of oxygen vacancies and Ce3+, thereby improving the activity of Fe-CeO2 for 2e-ORR.

Summary: In this study, dense porous carbons (DPCs) were prepared from oxidized coal liquefaction residue (OCLR) through chemical welding and homogenous activation. The OCLR exhibited decreased particle size, increased edge sites, and improved oxygen content with longer oxidation time. The resulting dense porous carbon from small-sized OCLR (ca. 5 nm) showed abundant edge oxygen-bearing groups, good electrical conductivity, large specific surface area (1368 m2 g-1), and high compaction density (0.98 g cm-3). As a supercapacitor electrode, it demonstrated good gravimetric capacitance and enhanced volumetric capacitance of 268.5 F g-1 and 263.1 F cm-3 at 1 A g-1, respectively. The assembled symmetric supercapacitor exhibited an enhanced volumetric energy density of 8.26 W h L-1 at 124.9 W L-1, as well as excellent cycle stability.
