Summary: TiO2/SBA-15 photocatalysts were prepared by impregnating low loading titania to SBA-15, which exhibited efficient adsorption and photodegradation for fast methylene blue removal. The low TiO2 loading enhanced TiO2 dispersion and maintained the SBA-15 porosity. The high interfacial interaction of TiO2/SBA-15 improved TiO2 photoresponse, resulting in a stronger redox ability. The pseudo-second-order kinetic model was followed for methylene blue removal on 10%TiO2/SBA-15, reaching 67% efficiency in 90 min. The synergy between adsorption and photodegradation was responsible for the fast methylene blue removal. The importance of maintaining the adsorption capacity in SBA-15 after TiO2 impregnation was highlighted for efficient adsorption-photodegradation processes.

Summary: The synthesis and design of heterojunction nanocomposites with remarkable photocatalytic performance remain a challenge. In this work, CuMn2O4/Co3O4 nanocomposite heterojunctions were fabricated using a sol-gel strategy with soft template assistance. The CuMn2O4/Co3O4 nanocomposites exhibited significant enhancement in degradation efficiency and achieved 100% degradation of tetracycline within 75 min. The enhanced photocatalytic ability was attributed to the construction of heterojunction, synergistic effect between CuMn2O4 and Co3O4, enlarged surface area, strengthened effective charge mobility, and narrowed bandgap energy.

Summary: As nations transition towards low or net zero carbon economies due to global climate change, the need for practical alternative fuels is urgent. Hydrogen gas is considered one of the most desirable substitutes for traditional hydrocarbons, but obtaining "green" hydrogen from low or zero carbon footprint sources presents challenges. Research focuses on practical techniques for producing "green" hydrogen through photocatalytic or photoelectrocatalytic processes. However, the capability of this technology to produce hydrogen at scale has faced significant issues. This road map article explores various aspects of photocatalytic and photoelectrocatalytic hydrogen generation, including processes, materials science, reactor engineering, and biomass reforming applications.

Summary: In this study, novel mesoporous n-p heterojunction CuCo2O4/Co3O4 photocatalysts were constructed for the first time through a sol-gel process. The obtained CuCo2O4/Co3O4 heterostructures showed a significantly higher photodegradation efficiency of tetracycline (TC) than pure Co3O4. The superior photocatalytic ability of CuCo2O4/Co3O4 heterostructures was attributed to the synergistic effect and proper pore structure with large surface area.

Summary: This article explores TiO2 nanomaterials as promising photocatalysts for NOx depollution from air under sunlight irradiation. Experimental results show that brookite TiO2 exhibits comparable photocatalytic activity to benchmark TiO2 P25 and higher selectivity towards the conversion of NOx into nitrate ions. The enhanced selectivity is attributed to the higher density of defects on brookite TiO2 surfaces, which facilitates the adsorption of NO2 while favoring the dissociative adsorption of water.

Summary: In this research, the UV-stimulated processes in the TiO2-COg system were studied using in situ FTIR spectroscopy and photoelectron spectroscopy. The kinetic dependences of the adsorbed CO intensity and background absorption, as well as the positions of the Fermi level in TiO2, were analyzed and compared before, during, and after UV irradiation. The reversible shift in the adsorption-desorption equilibrium was explained by changes in the electronic state of the photocatalyst under UV irradiation. The proposed mechanism of photostimulated CO adsorption and re-adsorption in the TiO2-COg system is described in detail, including the formation of strongly bound surface carbonates caused by the side reaction of CO photooxidation.

Summary: Destabilizing ligand-stabilized semiconductor nanocrystal solutions results in the formation of macroporous self-supporting nanocrystal networks called hydrogels, which have high surface accessibility. The delocalization of charge carriers in these gels extends their mobility and enhances photocatalytic reactions. Recent advances in colloid chemistry enable the synthesis of nanocrystals with specific physicochemical properties, which, when combined with nanocrystal-based hydrogels, can lead to novel materials with optimized photocatalytic properties. This study demonstrates that CdSe quantum dots, CdS nanorods, and CdSe/CdS dot-in-rod-shaped nanorods as nanocrystal-based hydrogels show significantly higher hydrogen production rates compared to their ligand-stabilized nanocrystal solutions. The gel synthesis through controlled destabilization by ligand oxidation ensures high surface-to-volume ratio, facilitates photocatalytic hydrogen production without a co-catalyst, and overcomes colloidal instability issues in photocatalysis. X-ray photoelectron spectroscopy and photoelectrochemical measurements confirm the advantageous properties of these 3D networks for photocatalytic hydrogen production.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
