Summary: The interaction between partially reduced nano-crystallite titanium dioxide (TiO2-x(F)) and MgH2 can lower the desorption temperature and improve the dehydrogenation kinetics. The synergistic effect between multivalent Ti species, in situ formed MgF2 and MgF2-xHx, as well as oxygen vacancies contribute to the improved hydrogen storage performance of MgH2.

Summary: Introducing oxygen vacancies (Vo) into TiO2 photocatalyst through N doping using dodecylamine as a structure-directing agent resulted in the successful synthesis of spherical anatase TiO2 nanostructures. These Vo-containing N-TiO2 spheres, decorated with 1 wt% Pt, showed excellent performance in hydrogen generation under UV-visible illumination. The enhanced photocatalytic activity is attributed to N-doping-induced oxygen vacancies (Vo) which inhibit the direct recombination of photogenerated carriers, and the presence of Pt co-catalysts that further suppress electron-hole pair recombination.

Summary: Modulating the activity of oxygen species in transition metal oxide catalysts is crucial for environmental catalytic oxidation reactions. In this work, the mobility of lattice oxygen and activation ability of gas oxygen over CoMn2O4 were effectively regulated by in situ solvothermal-induced lanthanum doping, leading to enhanced VOCs oxidation activity. The introduction of lanthanum species into the spinel lattice significantly increased the oxygen vacancies and weakened the metal-oxygen bond strength, resulting in higher mobility and reactivity of lattice oxygen and improved conversion of toluene to CO2 and H2O.

Summary: This study introduces a nanoetching technology to improve the photoelectrochemical (PEC) performance by exposing a large number of high-energy (101) crystal facets on rutile TiO2 nanorod films. The nanoetching technology significantly enhances charge separation and transfer efficiency, leading to improved PEC performance. The mechanism behind the enhancement is attributed to the reduced energy barrier for oxygen evolution reaction (OER) by shortening the distance between HO* intermediates on the rutile (101) facet and neighboring O-b. Additionally, the driving force for spatial charge separation between (110) and (101) facets promotes charge separation. This work offers a versatile nanotechnology for enhancing PEC performance.

Summary: In this study, TiO2-supported copper catalysts (CuOx/TiO2) with different ratio of oxygen vacancies (Ov) and Cu+ were synthesized, and the existence and amount of Ov and Cu+ species were characterized. The synergetic effect between Cu+ and oxygen vacancies was investigated, and Cu+ was found to be the adsorption site for CO molecules, while abundant Ov could effectively activate molecular oxygen to oxidize CO. The most suitable ratio between Cu+ and Ov was confirmed, and CuOx/TiO2 (Cu+ rich) catalyst exhibited superior CO oxidation activity compared to CuOx/TiO2 (Ov rich) catalyst.

Summary: In this study, 2D TiO2 nanosheets with abundant oxygen vacancies were used to fabricate a flower-like MgH2/TiO2 heterostructure with enhanced hydrogen storage performances. The heterostructure exhibited improved hydrogen desorption temperature, desorption rate, and capacity retention. The synergistic effects of multi-valance of Ti species, accelerated electron transportation caused by oxygen vacancies, formation of catalytic Mg-Ti oxides, and stabilized MgH2 NPs confined by TiO2 nanosheets contributed to the high stability and kinetically accelerated hydrogen storage performances of the composite. The strategy of using 2D substrates with abundant defects to support nano-sized energy storage materials to build heterostructure is promising for the design of high-performance energy materials.

Summary: Piezoelectric NiFe2O4 nanofibers with surface oxygen vacancies were successfully synthesized in this study. The piezoelectric catalytic degradation rates of organic dyes were increased by 75%, and the piezoelectric catalytic hydrogen peroxide generation in pure water was increased by 39%. The oxygen defects enhanced the charge transfer rate and activation of molecular oxygen, providing more reaction sites for the catalytic process. Superoxide radicals played a crucial role in the entire catalytic process, and force-generated electrons and holes migrated to the nanofiber surface, undergoing redox reactions under the internal electric field. This work provides a piezoelectric catalyst for efficient degradation of dyes and production of hydrogen peroxide.

The effects of calcination and activation with hydrochloric acid or a mixture of hydrochloric and orthophosphoric acid are compared. The activated red mud exhibits high catalytic activity, with hydrochloric acid activation being the most effective. However, the oxidation of the sulfur compounds is not complete, resulting in the formation of carbon monoxide.

Summary: The ecotoxicological effects of manufactured TiO2, cerium doped TiO2, and zirconium doped TiO2 were evaluated. TiO2 prepared using titanyl sulphate as a precursor showed toxicity to plant species, while TiO2 prepared using titanium (IV) isopropoxide was non-toxic. Cerium doped TiO2 with a low amount of cerium (<5.5 wt.%) was non-toxic and zirconium doped TiO2 stimulated plant growth. The presence of SO42- was identified as the chemical cause of TiO2 toxicity, and high cerium content in TiO2 led to the formation of toxic CeO2 nuclei.

Summary: The feasibility of using advanced oxidation processes (AOPs) for abatement of ammonia from livestock buildings was examined. Pilot plant experiments were conducted using a two-step unit containing a dry photolytic reactor (UV185/UV254/O-3) and a photochemical scrubber (UV254/H2O2). The unit efficiency was tested for different concentrations and air flows, and demonstrated high removal rates of ammonia, even at high flow rates. The combination of UV and ozone effectively removed ammonia from the aqueous phase without adjusting the pH. The cost efficiency of the technology was also assessed, showing promising results.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
