“…In recent years, the development of nanotechnology and nanomaterials has provided a new approach for improving the efficiency of pesticide application [ 6 – 15 ]. Nanoparticle formulations of pesticides have been proposed to produce a better spatial distribution of pesticides on leaf surfaces, owing to nanoparticles’ small size and large surface area, which provides better efficiency [ 16 – 19 ].…”

Nano-delivery systems for the active ingredients of pesticides can improve the utilization rates of pesticides and prolong their control effects. This is due to the nanocarrier envelope and controlled release function. However, particles containing active ingredients in controlled release pesticide formulations are generally large and have wide size distributions. There have been limited studies about the effect of particle size on the controlled release properties and biological activities of pesticide delivery systems. In the current study, avermectin (Av) nano-delivery systems were constructed with different particle sizes and their performances were evaluated. The Av release rate in the nano-delivery system could be effectively controlled by changing the particle size. The biological activity increased with decreasing particle size. These results suggest that Av nano-delivery systems can significantly improve the controllable release, photostability, and biological activity, which will improve efficiency and reduce pesticide residues.

“…The significant challenge leading to extensive use of the hydrogen energy system is to produce H 2 with a low-cost, stable, and highly efficient photocatalyst. − However, the current efficiency for photocatalytic water splitting is limited by the highly preferred recombination of photogenerated carriers in photocatalysts. Currently, constructing semiconductor heterojunctions has been demonstrated to be one of the most important approaches to promoting the hydrogen production efficiency because the the heterojunction can significantly improve the separation efficiency of photogenerated carriers. − …”

Quantum dots (QDs) have great potential to build heterojunctions for efficient photocatalytic hydrogen production because of the quantum size effects, whereas they are limited by the rigorous preparation. Herein, we report a facile sacrificial coating strategy toward the construction of the NiO QDs/TiO2 heterojunction. Shorter transmission distance of carriers and higher crystallinity between NiO QDs and TiO2 substrate are achieved to minimize the recombination of photoinduced electrons and holes. As a result, excellent performance of 1.35 mmol h–1 g–1 over the NiO QDs/TiO2 sample is achieved, which is 37 times higher than that of NiO/TiO2 and 56 times higher than that of pure TiO2. Furthermore, this is one of the best performances reported in heterojunctions made of NiO and TiO2.

“…The photocatalysis phenomenon is one of the best examples of how to clean air [ 1 , 2 , 3 ] and water [ 4 , 5 , 6 ] in a green way [ 7 ]. Furthermore, this photoinduced reaction is also presented in self-cleaning [ 8 , 9 , 10 ], antitumor activity [ 11 , 12 , 13 ], and self-sterilizing [ 14 , 15 , 16 ]. TiO 2 is the most employed photocatalytic element due to its low cost, chemical stability, non-toxicity, and high reactivity [ 17 ].…”

This work presents a comparative study related to the photocatalytic efficiency associated with wettability measurements and organic dye degradation, as well as other relevant properties (i.e., corrosion resistance, roughness, wettability, and adhesion to a substrate). The photocatalytic precursors are titanium dioxide nanoparticles (TiO2 NPs) which are dispersed onto a polymeric electrospun fiber matrix by using three different deposition techniques such as electrospraying, spraying, and dip-coating, respectively. In this work, the host electrospun matrix is composed of poly(acrylic acid) fibers crosslinked with cyclodextrin (β-CD), which shows a good chemical affinity and stability with the other deposition techniques which are responsible for incorporating the TiO2 NPs. In order to evaluate the efficacy of each coating, the resultant photocatalytic activity has been monitored by two different tests. Firstly, the reduction in the water contact angle is appreciated, and secondly, the degradation of an organic dye (Rhodamine B) is observed under UV irradiation. In addition, the final roughness, adherence, and pitting corrosion potential have also been controlled in order to determine which solution provides the best combination of properties. Finally, the experimental results clearly indicate that the presence of TiO2 NPs deposited by the three techniques is enough to induce a super hydrophilic behavior after UV irradiation. However, there are notable differences in photocatalytic efficiency on the Rhodamine B as a function of the selected deposition technique.
