“…However, it is actually hard to control two kinds of 1D material to array on one direction and form a line-to-line interface homogeneously. Natarajan [61] recently reported the fabrication of MWCNT-loaded TiO2 nanotube (TNT) composites by a hydrothermal method. They tried to obtain 1D/1D composites, but it was found that most of the junctions between MWCNTs and TiO2 nanotubes are still shaped as points.…”

Abstract:In this review, we provide an overview of recent progress in nanocarbons with different dimensions as noble-metal-free co-catalysts for photocatalysts. We put emphasis on the interface engineering between nanocarbon co-catalysts and various semiconductor photocatalysts and the novel properties generating of nanocarbon co-catalysts, also including the synthesis and application of nanocarbon-based photocatalyst composites.

“…More recently, titanium dioxide nanotubes (TNTs) were successfully used as efficient nanocomposites in the CWPO/CWAO for oxidative degradation of organic pollutants [4]. According to reported studies, TNTs have also interesting properties, such as high specific surface area and adsorption capacity, good ion-exchange property and low recombination rate by long electron transport distance along the tubular structure [4,38].…”

The saline polycarbonate wastewater was treated by catalytic wet peroxide oxidation. • The magnetite TNT/CNT nanocomposite was developed as CWPO catalyst. • The complete BPA, 68.78% of COD and 47.14% of TOC reduction was obtained in CWPO. • The reusability of the catalyst shows with slight decline after 4 consecutive runs. • The biodegradability of treated PCW using CWPO process was improved significantly.

The present work reports titanium dioxide (TiO2) photocatalyst composite based on human hair that can operate efficiently under visible light. The human hair melanin structure contains active sites, which can be described as a carbon compound derived from a Quinone where one of two oxygen atoms is bonded to a hydrogen radical and that can be reversibly photogenerated under visible or ultraviolet irradiation. The human hair‐derived microfibers (HHDMs) were created by the pyrolyzing hair at 850 °C, resulting in a rod‐like hollow structure. TiO2 was immobilized on the pyrolyzed hair by a simple self‐template method. The resulting composite was calcined at five different temperatures (150 to 350 °C). The HHDM and HHDM‐TiO2 morphologies and the chemical compositions were characterized using scanning electron microscopy (SEM), Energy‐dispersive X‐ray spectroscopy (EDX), X‐ray photoelectron spectroscopy (XPS), Fourier‐transform infrared spectroscopy (FTIR), and X‐ray powder diffraction (XRD). The HHDM‐TiO2 photocatalytic efficiency in degrading methylene blue was investigated and compared to that of a conventional TiO2 catalyst (P25). HHDM‐TiO2 was more effective for methylene blue degradation under visible light than the conventional P25 catalyst suspension due to the unique photosensitivity and porous structure of the composite. The catalyst calcined at 300 °C showed the best performance, which was 71% higher than that of the P25 catalyst.
