“…There are two peaks splitting at 1,451 cm À1 and 1,380 cm À1 due to asymmetric and symmetric O-C-O stretching in carboxylate group -TiO bridge structure (nano-CaCO 3 /TiO 2 coating), as shown in Figure 5 below (Kaur and Verma, 2014). The increment in Si-O-Si peak intensity at 1,045 cm À1 is attributed to saturated Si-O-Si crosslinking as the Sylgard forming a crosslinking with methyl groups, CH 2 of PDMS polymer.…”

Purpose This paper introduced the simple synthesis process of self-cleaning coating with fog-resistance property using hydrophobic polydimethylsiloxane (PDMS) polymer and nano-calcium carbonate (nano-CaCO3) and titanium dioxide (TiO2). Design/methodology/approach The synthesis method of PDMS/nano-CaCO3-TiO2 is based on sol-gel process. The crosslinking between PDMS and nanoparticles is driven by the covalent bond at temperature of 50°C. The 3-Aminopropyltriethoxysilane is used as binder for nanoparticles attachment in polymer matrix. Two fabrication methods are used, which are dip- and spray-coating methods. Findings The prepared coated glass fulfilled the requirement of standard self-cleaning and fog-resistance performance. For the self-cleaning test BS EN 1096-5:2016, the coated glasses exhibited the dust haze value around 20%–25% at tilt angle of 10°. For the antifog test, the coated glasses showed the fog haze value were below 2% and the gloss value were above 85%. The obtained results completely achieved the standard antifog value ASTM F659-06 protocol. Research limitations/implications Findings will provide an infrastructure support for the building glass to enhance building’s energy efficiency, cleaning performance and friendly environment. Practical implications This study proposed the simple synthesis method using hydrophobic polymer and nano-CaCO3 and nano-TiO2, which can achieve optimum self-cleaning property at low tilt angle and fog-resistance performance for building glass. Social implications The research findings have high potential for building company, cleaning building company and government sector. The proposed project capable to reduces the energy consumption about 20% per annum due to labor cost, time-consuming and safety during manual cleaning. Originality/value The novel method to develop self-cleaning coating with fog-resistance using simple synthesis process and fabrication method for building glass application.

Different amount of gold nanoparticles (1, 3, 5, 10 wt%) were deposited on the surface of synthesized titanium oxide nanowires (TiO 2 NWs) and Degussa P25 (TiO 2 -P25). The results evidenced the presence of small and dispersed gold particles on the surface of TiO 2 NWs and TiO 2 -P25 and an increase in the specific surface area of all the composites. The photocatalytic activity was characterized by measuring the hydrogen production by water splitting, using UV-vis radiation. Au@TiO 2 NWs catalysts showed the highest production of hydrogen (1,436 µmol hg −1 ), with a gold loading of 10 wt%, while in the case of Au@TiO 2 -P25 the hydrogen production was slightly lower (800 µmol hg −1 ), with a gold loading of 5 wt%. The enhancement in the hydrogen production was 11.5 times higher than that reported by the TiO 2 NWs catalyst (125 µmol hg −1 ) and 5.2 times higher than the TiO 2 -P25 (154 µmol hg −1 ). The activity of the catalysts was found to be dependent both on the surface area of the composites and on the amount of gold.

“…This result is supported by FTIR analysis in Figure 2(a). The functional groups of bending vibrations of Ti-O-Ti and bending vibrations of OH groups adsorbed onto the TiO 2 surface are shown for all the samples by peaks at 743 cm −1 and 1621 cm −1 , respectively [33,34]. Carbondoped TiO 2 samples show an additional peak at 1714 cm −1 , which can be attributed to stretching of the C = O bond [35,36].…”

The discharge of dyes in the textile industry leads to several hazardous effects on the environment. One of the most effective methods on treating dye-contaminated wastewater is photocatalytic degradation. TiO 2 has been widely used as a photocatalyst for wastewater treatment. Since the light absorption of TiO 2 is in the UV light range, however, doping of TiO 2 with a non-metal or metal element is needed to improve its absorption in the visible light range. In this study, TiO 2 photocatalyst was doped with carbon using sucrose as a carbon+e at ratios of 0.75:1 and 1:1. The surface area of TiO 2 after doping with carbon improved to two times the TiO 2 surface area. Additionally, the band gap energy of TiO 2 was successfully reduced to 2.38 eV after doping with carbon. In order to avoid the secondary pollutant problems, the carbon-doped TiO 2 was then immobilized with polyamide fibers at 1wt%, 2wt % and 3wt% to facilitate recollection of the photocatalyst. A photodegradation test was performed by degrading methylene blue under visible light irradiation using 70W halogen lamps with a total of 5 hours of time interval readings. The highest percentage degradation was recorded at 82.67% using immobilized 2wt% 1:1 carbon-doped TiO 2 in polyamide fibers.
