Summary: This study investigates how small changes in the lower size range of AuNPs affect the photoactivity of Au/TiO2, aiming to maximize the performance of low-metal-loading photocatalysts. Au/TiO2 photocatalysts prepared by precipitation-deposition methods and a speciation-controlled incipient wetness impregnation method exhibited significantly higher NOx elimination capacity than pristine TiO2. Among the photocatalysts, the speciation-controlled incipient wetness impregnation method achieved the highest gold dispersion and Au-TiO2 contact perimeter, providing the most active photocatalysts, confirming the positive effect of AuNPs size reduction. Additionally, it is proposed that the adsorption of nitrogen oxides species on gold plays a relevant role in the NO photooxidation process.

Summary: In this study, PAN-based activated carbon nanofibers were used as a carrier and framework for photocatalysts. TiO2 was deposited on the surface of pre-oxidized PAN nanofibers using supercritical carbon dioxide, and the fibers were activated by heat treatment to prepare TiO2/ACNF. The morphology, structure, and specific surface area of the modified nanofibers were analyzed, and the photocatalytic degradation of methyl orange was tested. The results showed that TiO2 nanoparticles can be uniformly loaded on the surface of pre-oxidized PAN nanofibers after supercritical treatment, and the TiO2/ACNF has a high specific surface area of 422.8 m2/g, exhibiting superior adsorption and photocatalytic degradation performance.

Summary: This paper proposes a deposits control method based on the deposits boundary of the ATS structure. Engine bench test was used to obtain the deposits boundary map for four different rotational speeds, resulting in high, medium, and low deposition risk regions. The middle line of the medium risk region was used as the deposits control strategy value for urea injection. Using the deposits boundary control strategy, urea consumption was reduced by 11.2% and 15.3% under WHTC cycle and WHSC cycle conditions, respectively. The engine can evaluate the urea injection quantity within the deposits risk range based on the deposits boundary to comply with emission regulations and avoid ATS deposits failures.

Summary: Monoterpene photooxidation plays an important role in the formation of secondary organic aerosols (SOA), and this study investigates the factors influencing SOA yield from alpha-pinene and Delta-3-carene photooxidation. The results show that oxidation conditions, addition of NO, and the molecular structure of volatile organic compounds (VOCs) can all affect SOA formation. The study also reveals that the composition of the photooxidation products and the SOA yield differ between alpha-pinene and Delta-3-carene.

Summary: In this study, a Ni(OH)(2)/CNT/CF composite electrode was developed and characterized to investigate its electrode kinetics for enhanced urea oxidation reaction (UOR) performance. The electrode exhibited satisfactory UOR performance with higher oxidation current and lower overpotential, attributed to the active and reversible Ni2+/Ni3+ redox reaction of the composite. The inclusion of CNTs in the electrode structure led to increased reaction surface area and electrical conductivity, resulting in lower charge transfer resistance compared to conventional electrodes.

Summary: The AUV/chlorine/AC-TiO2 process achieves efficient micropollutant abatement and DBP control by enhancing HO center dot production and DBP in situ adsorption, respectively. The use of activated carbon (AC) in the process results in higher degradation rates and reduced formation of undesired disinfection byproducts (DBPs). AC acts as an electron conductor and DO adsorbent, leading to increased levels of HO center dot and decreased formation of DBPs. This study provides a new strategy for designing catalysts with photocatalytic and adsorption properties to improve micropollutant abatement and DBP control in the UV/chlorine process.

Summary: Activated carbon is produced by physical or chemical activation methods. While physical activation methods are commonly used in industry due to lower production costs, they are less effective compared to chemical activation methods in terms of pore development. A novel pressurized physical activation method is proposed to increase activating agent diffusibility and pore development, resulting in activated carbon with higher specific surface area and unique pore size distribution.

Summary: Activated carbon is a suitable adsorbent for ethanol refrigerant adsorption heat pumps (AHPs). Chemically activated carbon with highly developed pore structures has good ethanol adsorption, but it is expensive. Physical activation produces inexpensive activated carbon but with limited pore development. A pressurized physical activation method was developed to produce activated carbon with well-developed pore structure, and it showed comparable or higher ethanol uptake than chemically activated carbon on a weight and volume basis.

Summary: This study closely examined the correlation between the anisotropic texture and (002) molecular stacking property of spinnable mesophase pitch (SMP). It was found that SMP is a specific solution consisting of mesogenic and solvent components, with the mesogenic component composed of a cluster unit of (002) stacked molecular sheets. The anisotropic texture of SMP is strongly correlated with the height of (002) molecular stacking.

Summary: The optimal conditions for facilitating graphene-zipping reactions whilst minimizing graphene stacking processes in highly mesoporous templated carbons were examined. Graphene-zipping reactions occur at temperatures between 1173 and 1873 K, leading to a 1100 fold increase in average graphene-domain size. At temperatures above 2073 K, the carbon framework loses its porosity due to the development of graphene-stacking structures.
