“…370,371 Abatement of harmful nitric oxide air pollutants requires the selective catalytic oxidation of NO to NO 2 , which is a key step in the catalytic reduction of NO x by ammonia to produce dinitrogen. 370,371 Removal of excess ammonia in exhaust streams proceeds through catalytic NH 3 oxidation to N 2 and H 2 O. 372 Du and co-workers used 1064 nm, 1.2 ms pulses on Ti bulk targets in 0.45 mM aqueous NaAuCl 4 solution to produce titanium oxide supported gold nanocomposites for the thermochemical oxidation of CO. 373 Nanoparticle sizes were centered at 5.5 nm (Au) and 25.0 nm (TiO 2 ).…”

Catalysis is essential to modern life and has a huge economic impact. The development of new catalysts critically depends on synthetic methods that enable the preparation of tailored nanomaterials. Pulsed laser in liquids synthesis can produce uniform, multicomponent, nonequilibrium nanomaterials with independently and precisely controlled properties, such as size, composition, morphology, defect density, and atomistic structure within the nanoparticle and at its surface. We cover the fundamentals, unique advantages, challenges, and experimental solutions of this powerful technique and review the state-of-the-art of laser-made electrocatalysts for water oxidation, oxygen reduction, hydrogen evolution, nitrogen reduction, carbon dioxide reduction, and organic oxidations, followed by laser-made nanomaterials for light-driven catalytic processes and heterogeneous catalysis of thermochemical processes. We also highlight laser-synthesized nanomaterials for which proposed catalytic applications exist. This review provides a practical guide to how the catalysis community can capitalize on pulsed laser in liquids synthesis to advance catalyst development, by leveraging the synergies of two fields of intensive research.

The emission characteristics of pollution gases produced via the combustion of food waste were studied through a laboratory-scale electrically heated tube furnace. The results showed that the pollution gases generated from the combustion of food waste were CO, H2 and NOx. Each emission curve of CO had a peak. When the combustion temperature rose from 400 °C to 1000 °C, the peak first increased (from 400 °C to 700 °C) and then decreased (from 800 °C to 1000 °C). However, the burnout time shortened with the increase in temperature. Therefore, food waste should be combusted at a higher temperature than 700 °C from the perspective of reducing CO emissions. The emissions of H2 were similar to those of CO. In other words, if CO emissions increased, H2 emissions also increased in the same temperature range. Some NOx emission curves had two peaks (the combustion of cooked rice at 1000 °C; the combustion of vegetable leaves in the temperature range of 600 °C to 1000 °C). The higher the combustion temperature, the higher the second NOx emission peak. NOx emissions from the combustion of cooked rice were greater in the temperature range of 400 °C to 500 °C, whereas for vegetable leaves, that temperature range was from 600 °C to 700 °C. Hence, from the viewpoint of reducing pollution gases, food waste should be combusted at a higher temperature than 700 °C.

“…The NO catalytic oxidation catalysts current being studied are mainly categorized into the following groups: noble metals, zeolites, carbon materials, metal oxides, and perovskite. [14][15][16][17][18] Among them, as reviewed in the previous paper, 13 transition metal-oxides are the main targets of research for NO catalytic oxidation by virtue of their variable chemical valence, rich pore structure, low price, high abundance in nature, and low secondary pollution. Currently, studies on SCO catalysts have mainly focused on Mn-based, [19][20][21] Cr-based, 22,23 Co-based, 24 and Fe-based.…”

BACKGROUND In this paper, Mn–Co binary oxides prepared by an (NH4)2CO3‐assisted co‐precipitation method were used for the catalytic oxidation of NO at low temperatures. RESULTS Experimental results showed that the Mn–Co binary catalysts prepared with manganese acetate and cobalt nitrate exhibited the highest oxidation activity, obtaining a NO conversion of 76% at 200 °C and 80% at 250 °C. The passivation effect of SO2 was found to be irreversible in the examination of the resistance to SO2 or/and H2O(g). Furthermore, characterization by X‐ray Photoelectron Spectroscopy (XPS), Fourier Transform infrared spectroscopy (FTIR), and in situ Diffuse Reflectance Infrared Fourier Transform spectroscopy (DRIFTs) revealed that the passivation effect was due to the bidentate and surface or bulk‐like sulfates generated on the surface of the catalyst. CONCLUSION The analysis of intermediate species during the in situ DRIFTs characterization revealed that these sulfate species competed with nitrate/nitrite species for adsorption and affected the activity. Moreover, the poisoned catalysts could be regenerated to remove the majority of the bidentate and surface or bulk‐like sulfates from the surface and maintain the excellent NO catalytic oxidation activity. © 2021 Society of Chemical Industry (SCI).
