Special Issue Information

Dear Colleagues,

Catalysis is one of the most important topics in material science. It is an outstanding route for the control of chemical reactions through changing the kinetics based on the specific physical–chemical properties of materials, especially for nano-sized materials. Recently, there has been great advancement in this subfield during the progress of nanomaterial science. For instance, photocatalytic water splitting is an encouraging strategy for solar energy conversion. Many factors, including light absorption, charge separation, reaction activity, have been extensively studied. Based on the improvement of catalytic property, the application has been extended to CO2 reduction, N2 reduction, as well as traditional organic synthesis. Similarly, the electrochemical process for the above catalytic process is also attractive. The different initial energy provides a higher energy density for the potential practical application. The various strategies, such as surface facet modification, band structure modification, and external field assistance, have been areas of interest for a while. The recent progress is encouraged to be reported to further improve this subfield. This Special Issue aims to cover the recent progress and trends in the synthesis, characterization, and applications of novel heterogeneous catalysts.

Ni-H-Beta catalysts for ethylene oligomerization (EO) were prepared by ion exchange of NH4-Beta and H-Beta zeolites with aqueous Ni(NO3)2 and characterized by H2-temperature-programmed reduction (TPR), NH3-temperature-programmed desorption (TPD), and diffuse-reflectance infrared Fourier-transform spectroscopy (DRIFTS).

Ni-H-Beta catalysts for ethylene oligomerization (EO) were prepared by ion exchange of NH4-Beta and H-Beta zeolites with aqueous Ni(NO3)2 and characterized by H2-temperature-programmed reduction (TPR), NH3-temperature-programmed desorption (TPD), and diffuse-reflectance infrared Fourier-transform spectroscopy (DRIFTS). Quadruple exchange of NH4-Beta at 70 °C resulted in 2.5 wt.% Ni loading corresponding to a Ni2+/framework aluminum (FAl) molar ratio of 0.52. [NiOH]+ and H+ are the primary charge-compensating cations in the uncalcined catalyst, as evidenced by TPR and DRIFTS. Subsequent calcination at 550 °C in air yielded a Ni-H-Beta catalyst containing primarily bare Ni2+ ions bonded to framework oxygens. Quadruple exchange of H-Beta at 70 °C gave 2.0 wt.% Ni loading (Ni2+/FAl = 0.41). After calcination at 550 °C, the resulting Ni-H-Beta catalyst comprises a mixture of bare Ni2+ ions: [NiOH]+ and NiO species. The relative abundance of [NiOH]+ increases with the number of exchanges. In situ pretreatment at 500 °C in flowing He converted the [NiOH]+ species to bare Ni2+ ions via dehydration. The bare Ni2+ ions interact strongly with the Beta framework as evidenced by a perturbed antisymmetric T-O-T vibration at 945 cm−1. DRIFT spectra of CO adsorbed at 20 °C indicate that the Ni2+ ions occupy two distinct exchange positions. The results of EO testing at 225 °C and 11 bar (ethylene) suggested that the specific Ni2+ species initially presented (e.g., bare Ni2+, [NiOH]+) did not significantly affect the catalytic performance.

Abstract: Powder metallurgical porous titanium-based nanostructure composites are attractive for high-tech applications of energy conversion and energy storage due to their three-dimensional (3D) micro-nano hierarchical structure. This study presents a novel sandwich nanostructure of MnO2/TiO2/porous Ti that was successfully prepared by a chemical co-precipitation reaction between KMnO4 and MnSO4. The composite structural and morphological analysis of the nano-coatings were carried out by means of X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), respectively. The results indicate that the surface of coatings is uniform and compact, with a high load capacity. The MnO2 nanoparticles are filled onto the TiO2 nanowire formed by the hydrothermal method. The electrochemical properties of the resultant were investigated by testing the charge/discharge curves and cyclic voltammetry of a three-electrode system. It showed that MnO2/TiO2/porous Ti electrode has the best capacitor performance and that nano-MnO2 coatings significantly decrease the corrosion currents densities. It indicates that the nano-MnO2 coatings exhibit excellent anti-corrosion properties at room temperature and better capacitance performance.
