Summary: Graphitic carbon nitride (g-C3N4) shows great potential as a photocatalytic material for hydrogen production, but its efficiency is low, and it suffers from fast recombination rate of charge carriers, limited visible-light absorption, and low surface area. Strategies such as pH control, morphology control, doping, metal deposition, constructing heterojunction or homojunction, dye-sensitization, etc., have been used to improve the photocatalytic performance of g-C3N4.

Summary: Cu2O rhombic dodecahedra and cubes functionalized with 4-nitrophenylacetylene were used as photocatalysts for the oxidation of aryl sulfides to produce aryl sulfoxides. Under the supply of oxygen and blue LED light, the reaction could be completed in 12 hours in a water and methanol mixed solution. High product yields and excellent selectivity for sulfoxides over sulfones were achieved, with a thioanisole to methyl phenyl sulfoxide yield of 98%. Mechanistic study revealed the involvement of photogenerated electrons, holes, and superoxide radicals in the oxidation reaction. The simple preparation of the photocatalyst and molecular functionalization demonstrate the effectiveness of surface-controlled ionic solids as photocatalysts for organic transformations.

Summary: Efficient photocatalysts for water oxidation were developed by integrating heteronuclear bimetallic polyphthalocyanine (PPc) catalysts with particulate bismuth vanadate (BiVO4) as the photosensitizer. The photocatalytic activity for water oxidation was modulated by tuning the Fe/Co ratio of polyphthalocyanines. At an optimal Fe/Co ratio of 3:1, the resulting Fe(3)CoPPc-BiVO4 hybrid exhibited an excellent oxygen evolution rate of 4557 μmol g(-1) h(-1) under visible light irradiation, which is nearly two orders of magnitude greater than that of pristine BiVO4 and superior to those of the corresponding homometallic counterparts. The presence of a large population of high-valent Fe/Co molecular species, due to favorable interfacial charge transfer and upshift of the d-band centers of metal sites toward Fermi level, was suggested to lower the energy barrier for O-O bond formation and promote the oxidation of water.

Summary: The use of biostimulants, such as oligosaccharins, can improve tomato yield under stress conditions without negatively impacting the environment. Applying oligosaccharins to the roots decreases the concentration of certain compounds in the fruit, while applying them via the leaves does not have this effect. The stimulatory effect of oligosaccharins on yield is more evident under lower temperature-stress.

Summary: This paper reviews the impact of different stages of beer-making on the behavior of pesticide residues. The use of pesticides on barley and hop can result in the presence of pesticide residues in beer. Factors such as pH, temperature, water content, and physical-chemical properties of pesticides play important roles in determining the fate of residues. Most pesticides show a decrease in concentration during the brewing process, but maltsters should pay attention to hydrophobic pesticides while brewers should control hydrophilic pesticides to maintain the quality and organoleptic properties of beer.

Summary: The presence of emerging micropollutants in the environment has become a significant threat to human health and aquatic ecosystems. These micropollutants, including pharmaceuticals and pesticides, enter the environment through human activities and can be found in various water sources. Conventional wastewater treatment plants are not effective in removing a large portion of these pollutants, particularly pharmaceuticals, leading to continuous contamination of freshwater systems. In this study, the effectiveness of TiO2 as a photocatalyst combined with Na2S2O8 as an oxidant was evaluated for the treatment of wastewater effluent contaminated with pharmaceutical residues. The results showed that this solar heterogeneous photocatalysis method significantly enhanced the removal of pharmaceuticals from the wastewater effluent. However, the presence of dissolved salts and organic carbon in the wastewater effluent slowed down the degradation process. The study also found that macrolides had the longest degradation time in wastewater effluent compared to other compounds studied. This methodology is particularly relevant in water-scarce areas with abundant sunlight, such as the southeast of Spain.

Summary: This study demonstrates the efficiency of solarization-ozonation techniques for the removal of pesticides in soil. The combination of solarization and ozonation treatment was found to be effective for all the studied pesticides in both fresh and aged contaminated soils. However, the removal efficiency was lower for aged contaminated soils due to increased adsorption of pesticides. A pilot trial in a commercial farm soil showed a significant degradation of pesticides after 40 days of treatment. The results suggest that this combination of techniques holds promise for pesticide degradation in soil.

Summary: Laboratory illumination is strong enough to create a photostationary state (PSS) of amphiphilic azo-benzene compounds in water. The [cis]PSS/[trans]PSS ratios were observed to be 0.33-1.2 in D2O and 0.37-3.8 in dimethyl sulfoxide-d6. ortho-Fluoroazobenzene amphiphiles show higher cis-isomer concentration at equilibrium compared to non-fluorinated compounds due to differences in optical absorption profiles. The kinetics of isomerization were measured using UV-Vis spectroscopy and the ratio of trans-to-cis rates does not directly correlate with the observed PSS. The half-life for PSS formation is 40 minutes for fluorinated compounds and 80 minutes for non-fluorinated compounds.

Summary: This study designed an integrated structure of Cu2O@Au/Cu2O heterostructure particles, which achieved significantly enhanced photocatalytic performance by simultaneously considering the integrated structural characteristics and localized surface plasmon resonance (LSPR) effect. Experimental characterization and theoretical simulation confirmed the three-in-one synergy of the integrated heterostructure, including the LSPR effect of Au nanoparticles, the light scattering based on core-shell heterostructure, and the effective charge separation based on inter-embedded heterostructure. The concept of integrated heterostructure cooperated with LSPR effect provides a new strategy for designing future catalysts.

Summary: In this study, the recombination of separated ion-radical states (SIRS) in PAPh films was analyzed, and it was found that the contribution of X-SIRS recombination to total luminescence varies with different environments. It was also shown that the recombination of labile SIRS is independent of the nature of the atmosphere. The study theoretically substantiated that SIRS recombination can occur via the transfer of both positive and negative charges, and the efficiency of thermal activation of recombination processes depends on the ratio of radiant and conductive channels of energy transfer.

Summary: Bifunctional hybrids containing photochromic indolyl(thienyl) diarylethenes and an ionochromic rhodamine moiety connected by a dimethylene spacer were synthesized. These hybrids exhibit absorption at 450-455 nm and fluorescence at 560 nm in toluene. UV light triggers ring-closed non-fluorescent diarylethene formation, which can be reversed under visible light or in the dark. In the presence of H+ cation, a naked eye effect is observed with the opening of the rhodamine-spirolactam ring and a pink-crimson coloration at 561 nm accompanied by intense long-wavelength emission at 586 nm. This process is reversible by exposure to triethylamine, as confirmed by NMR experiments. The light-induced isomerizations and proton-induced transformations were explained using computational methods. Reversible switching of fluorescent properties can be achieved by light irradiation and proton.
