Special Issue Information

Dear Colleagues,

Catalytic technology at the forefront of air pollution control involves advanced methods for reducing harmful emissions from industrial processes and vehicle exhausts. These cutting-edge catalysts are designed to enhance the conversion efficiency of pollutants such as carbon monoxide (CO), nitrogen oxides (NOx), volatile organic compounds (VOCs), and particulate matter (PM) into less harmful substances. Innovations in catalytic materials, including noble metals and metal oxides, have developed more efficient and durable catalysts. These advancements allow for lower operating temperatures, increased resistance to poisoning, and a longer service life, thereby significantly contributing to the mitigation of air pollution and improving overall environmental quality.

We invite submissions for a Special Issue of our journal focused on atmospheric environmental catalysis. This Issue aims to showcase the latest research and developments in the field, emphasizing the role of catalytic technologies in addressing air pollution challenges. We seek high-quality, original research articles and review papers that explore innovative catalyst designs, mechanisms of action, and the application of catalytic processes for the abatement of pollutants, such as CO, NOx, VOCs, and PM. Contributions that discuss the scalability of catalytic solutions are particularly welcome. We encourage researchers and experts from academia and industry to submit their work for this important and timely Special Issue.

The pathways and mechanistic aspects of H2-SCR over precious metal-based catalysts is still under debate. This study focusses on low loaded platinum-based catalysts (0.07–0.3%) in a large temperature range (50–500 °C), with special focus on (i) the role of NH3 as a possible intermediate species, (ii) the origin of the undesired N2O emission and (iii) the platinum sites involved in the H2-SCR deNOX reactions. Up to 60 °C, the N2O selectivity was close to 100%, with no influence of the presence of oxygen in the 50–100 °C temperature range. Ammonia formation was observed at relatively low temperatures (from 60 °C), but its reactivity was then limited. All these low temperature reactions were associated with the same platinum sites, probably a mix of edge and face sites. The maximum outlet NH3 was observed around 100 °C and the role of the NH3-SCR in the whole H2-SCR process appeared very limited. On the contrary, the ammonia oxidation by O2, which started near 120 °C, significantly contributed to the H2-SCR process and appeared responsible for the second N2O emission peak (150–500 °C). This reaction did not imply the same platinum sites and appears mainly dependant on the platinum particle size. Full article

Nitrogen oxides (NOx) emissions pose environmental and health risks. Selective catalytic reduction (SCR) is effective for NOx removal, and using CO as a reductant can eliminate both NOx and CO. This study explores CuCe catalysts on SiO2, Al2O3, and TiO2 for CO-SCR. Results show catalytic activity relates to the synergy between lattice oxygen and CuCe species. TiO2 enhances this interaction, promoting Cu+ and lattice oxygen for NO adsorption and dissociation. The CuCe/TiO2 catalyst achieves 100% NO conversion at 300 °C and 40.2% at 100 °C, indicating excellent low-temperature performance. These findings are valuable for developing efficient SCR catalysts.

In recent decades, photocatalysis has received huge attention as a way to address the main environmental challenges affecting planet Earth. Among these, the control of CO2 emission and its concentration in the atmosphere, as one of the greenhouse gases causing global warming, is of primary importance. This study focuses on the hydrothermal preparation of doped Ba and Ca-based titanates as efficient photocatalytic materials for CO2 photoreduction under solar light. The materials were characterized by SEM-EDX, XPS, FT-IR ATR, DRS, CHNS, XRD, and N2 physisorption analyses, and tested for gas-phase methane production from the target reaction. According to the results, the visible light harvesting properties were significantly improved with C and N doping, where glucose and a bio-based chitosan acted as the C and C+N sources, respectively. In particular, C-Ba-based titanate (CBaT) indicated the highest CH4 productivity, 2.3 µmol/gcat, against zero activity of the corresponding bare titanate structure, BaT. The larger surface area and pore volume, as well as its narrower band gap, are suggested as the major reasons for the promising performance of CBaT. This work provides new insights for the facile fabrication of efficient photoactive perovskite materials with the aim of CO2-to-CH4 photoreduction under solar light. Full article

Pt/TiO2 and Pt-Eu2O3/TiO2 catalysts were prepared via the impregnation method for catalytic oxidation of CO. The Pt-2Eu2O3/TiO2 catalyst exhibited better CO oxidation activity as well as greater SO2 resistance than the Pt/TiO2 catalyst. For the inlet gas consisting of 0.8% CO, 5% O2, and balanced N2, the lowest complete conversion temperatures (T100) of CO were 120 °C and 140 °C for the Pt-2Eu2O3/TiO2 and Pt/TiO2 catalysts, respectively. During the 72 h SO2-resistance test at 200 °C under an inlet gas composition of 0.8% CO, 5% O2, 15% H2O, 50 ppm SO2, and balanced N2, the CO conversion on the Pt-2Eu2O3/TiO2 catalyst remained >99%, while that on the Pt/TiO2 catalyst gradually decreased to 77.8%. Pre-loading 2 wt% Eu2O3 on TiO2 enhanced the dispersion of Pt, increased the proportion of Pt0, and facilitated the adsorption and dissociation of H2O, all of which promoted CO oxidation. SO2 preferentially occupied the Eu2O3 sites by forming stable sulfates on the Pt-2Eu2O3/TiO2 catalyst, which protected the Pt active sites from poisoning. The OH* species produced from the dissociation of H2O played a significant role in promoting CO oxidation through the formation of COOH* as the key reaction intermediate. The developed Pt-2Eu2O3/TiO2 catalyst has great application potential in terms of the removal of CO from industrial flue gases. Full article

Accelerated industrialization and surging energy demands have led to continuously rising atmospheric CO2 concentrations. Developing sustainable methods to reduce atmospheric CO2 levels is crucial for achieving carbon neutrality. Concurrently, the rapid development of new energy vehicles has driven a significant increase in demand for lithium-ion batteries (LIBs), which are now approaching an end-of-life peak. Efficient recycling of valuable metals from spent LIBs represents a critical challenge. This study employs conventional hydrometallurgical processing to recover valuable metals from spent LIBs. Subsequently, Ni-doped Co3O4 (Ni:Co3O4) supported on the natural mineral attapulgite (ATP) was synthesized via a sol–gel method. The incorporation of a small amount of Ni into the Co3O4 lattice generates oxygen vacancies, inducing a localized surface plasmon resonance (LSPR) effect, which significantly enhances charge carrier transport and separation efficiency. During the photocatalytic reduction of CO2, the primary product CO generated by the Ni:Co3O4/ATP composite achieved a high production rate of 30.1 μmol·g−1·h−1. Furthermore, the composite maintains robust catalytic activity even after five consecutive reaction cycles. Full article
