Abstract In our recent studies, we have investigated the tunability of optical properties of zinc oxide nanoparticles (ZnO NPs) through surface modification with organosilane surfactants. In the present paper, the effect of ZnO NPs modified with variable amount of 3-(trimethoxysilyl)propylmethacrylate (MPS) surfactant was investigated toward the photocatalytic degradation of methylene blue (MB), using two different UV light sources emitting at 254 nm and 365 nm. While the maximum photodegradation efficiency of 63% was reached by ZnO NPs loaded with the highest concentration of MPS upon exposure at 254 nm, in the case of UV exposure at 365 nm an opposite photodegradation trend was observed. Actually, a significant photodegradation efficiency of 95% was recorded by the unmodified ZnO, followed by ZnO NPs modified with 2% MPS for which the photodegradation efficiency amounted to 80%, thus highlighting their best photocatalytic performance.

Nitrogen-doped carbon nanotubes coated with zinc oxide nanoparticles (ZnO@NCNT) were prepared via a sol–gel route as sulfur encapsulator for lithium/sulfur (Li/S) batteries. The electrochemical properties of the S/ZnO@NCNT composite cathode were evaluated in Li/S batteries. It delivered an initial capacity of 1032 mAh·g−1 at a charge/discharge rate of 0.2C and maintained a reversible capacity of 665 mAh·g−1 after 100 cycles. The coulombic efficiency of the cathode remains unchanged above 99%, showing stable cycling performance. X-ray photoelectron spectroscopy analysis confirmed the formation of S–Zn and S–O bonds in the composite. This indicates that an enhanced cycling and rate capability of the S/ZnO@NCNT composite could be ascribed to advantages of the ZnO@NCNT matrix. In the composite, the active ZnO-rich surfaces offer a high sulfur-bonding capability and the NCNT core acts as a conductive framework providing pathways for ion and electron transport. The as-prepared S/ZnO@NCNT composite is a promising cathode material for Li/S batteries.
