By means of high-speed emulsification and ultrasonic dispersing, emamectin benzoate (EB)−sodium lignosulfonate (SL) nanoformulation (EBSLN f ) with a particle size of 150−250 nm was developed by the electrostatic selfassembly of SL and EB. The morphology of the nanoformulation was characterized by UV, IR, dynamic light scattering, fluorescence spectra (FS), scanning electron microscopy, and transmission electron microscopy. The results of antiphotolysis and the controlled release test for EBSLN f showed that the antiphotolysis ability of the nanoformulation is four times higher than that of the commercial EB-emulsifiable concentrate, and the nanoformulation has a pH-responsive controlled release function. The release ratio in different pH media was acidic > neutral > basic. Moreover, the insecticidal effective duration of EBSLN f was more than one time longer than that of EB-suspension concentrate in the greenhouse. Therefore, EBSLN f has broad application prospects in agricultural production and environmental protection because of its easy preparation, low cost, and being environment-friendly. Thus, the strategy is suitable for large-scale industrial production.

Fe 2 O 3 /γ-Al 2 O 3 catalysts were prepared using the wet impregnation method and characterized by Xray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and nitrogen adsorption-desorption. The continuous catalytic wet hydrogen peroxide oxidation of an aqueous phenol solution over Fe 2 O 3 /γ-Al 2 O 3 was studied in a fixedbed reactor. The effects of several factors, such as the weight hourly space velocity (WHSV), particle size, reaction temperature, H 2 O 2 concentration, and initial pH, were studied to optimize the operation conditions for phenol mineralization. For a 1 g L −1 phenolic aqueous solution, the phenol was nearly completely removed and chemical oxygen demand (COD) removal was approximately 92 % at steady-state conditions with a WHSV of 2.4×10 −2 g PhOH h −1 g cat −1 at 80°C with 5.1 g L −1 H 2 O 2 . The long-term stability of the Fe 2 O 3 / γ-Al 2 O 3 catalyst was also investigated for the continuous treatment of phenolic water. The removal of phenol and COD exhibited a slowly decreasing trend, which was primarily due to the complexation of active sites with acid organic compounds and the adsorption of intermediate products. The deposition of organic carbon and Fe leached from the catalyst had a small role in the partial deactivation of the catalyst. The Fe leached from the catalyst partially contributed to the phenol removal during a short run. However, this contribution could be neglected after 36 h because the Fe leached from the catalyst decreased to approximately 5 mg L −1 .

H-TiNTs were used as catalysts for the oxidation of dibenzothiophene. Compounds existing in fuels do not show any influence on DBT removal. Ti-hydroperoxide is responsible for the superior selectivity of H-TiNTs. The selective oxidation mechanism of H-TiNTs was proposed.
