Noble metal-based bimetallic alloy nanostructures became popular for methanol oxidation reaction (MOR) in order to lower the high cost of the Pt catalyst and improve the catalyst activity as well as their CO tolerance. Fabrication of the secondary structures of bimetallic alloy nanocrystal clusters is desired due to their abundant accessible active sites and enhanced stability. Herein, for the first time, we prepared novel Pt-Cu bimetallic alloy nanocrystal clusters (Pt-Cu BANCs) in the presence of poly(diallyldimethylammonium chloride) (PDDA). The selective use of PDDA and control of the amount of PDDA are critical to the controlled fabrication of secondary structures with nanograins assembled together. The Pt-Cu BANCs offered abundant active sites available and enhanced durable stability, and are investigated to be high-performance electrocatalysts for MOR (i.e. the ECSAs of Pt-Cu BANCs and the specific current density of methanol oxidation on Pt-Cu BANCs are 73.9 m2/g and 3.36 mA·cm-2, respectively), which are far better than those of commercial Pt/C and Pt black. Our results reported herein developed an effective strategy of polyelectrolyte-assisted soft reduced process for the creation of the secondary structures of bimetallic alloy nanocrystal clusters, which would be used as enhanced catalysts in the field of clean energy.

Photocatalytic TiO2 coatings are famously known for their excellent self-cleaning behavior, where very thin water layer formed on the superhydrophilic surface can easily wash-off the dirt particles while flowing. Here we report the preparation of the optically transparent, adherent, highly wettable towards water and photocatalytic SiO2-TiO2 coatings on polycarbonate (PC) substrate for self-cleaning applications. The silica barrier layer was applied on UV-treated PC substrate before spin coating the SiO2-TiO2 coatings. The effect of different vol% of SiO2 in TiO2 and its influence on the surface morphology, mechanical stability, wettability, and photocatalytic properties of the coatings were studied in detail. The coatings prepared from 7 vol% of SiO2 in TiO2 showed smooth, crack-free surface morphology and low surface roughness compared to the coatings prepared from the higher vol% of SiO2 in TiO2. The water drops on this coating acquires a contact angle less than 10° after UV irradiation for 30 min. All the coatings prepared from different vol% (7 to 20) of SiO2 in TiO2 showed high transparency in the visible range.

The formation of an air-column on a superhydrophobic surface: the superhydrophobic coating is surrounded by blue colored water forming an air column, and water acquires a height of nearly 5 mm around the boundaries of the superhydrophobic coating. This confirms that the superhydrophobic surface strongly repels water and always remains dry.

In nature, numerous biological surfaces depict hierarchical micro- and nano-structures with low energy surfaces that offer the superhydrophobic properties with low water adhesion. The superhydrophobic coatings were prepared using sol–gel derived SiO2 micro-particles by spray method. A methyltrimethoxysilane (MTMS) was used as a sol–gel precursor to prepare a coating sol. The entire spray coating process is a single-step and takes place at 70 °C temperatures. The surface morphological studies showed that the size of SiO2 particles were between 8 and 14 μm in diameter. These different diameter SiO2 micro-particles form hierarchical micro-structure which facilitates to reduce solid/water interface. The prepared superhydrophobic coatings showed static water contact angle (θ) of 162° ± 2° and roll-off angle of 6° ± 1°. The wetting properties and surface morphology of the coatings were investigated by static and dynamic water contact angle measurements and scanning electron microscopy, respectively. The characterization of the coatings by Atomic Force Microscopy and Fourier transformation infrared spectroscopy was also made. The resulting hierarchical surface morphology can be easily tuned over large areas by simple spray method.

Wettability of solid surfaces is a crucial concern in our daily life as well as in engineering and science. The present research work describes the room temperature (27 °C) synthesis of adherent and water repellent silica films on glass substrates using vinyltrimethoxysilane (VTMS) as a hydrophobic reagent by a single step sol–gel process. The silica sol was prepared by keeping the molar ratio of tetraethoxysilane (TEOS), methanol (MeOH), water (H2O) constant at 1:14.69:5, respectively, with 0.01 M NH4F throughout the experiments and the VTMS/TEOS molar ratio (M) was varied from 0 to 0.97. The effects of M on the surface structure and hydrophobicity have been researched. The static water contact angle as high as 144° and water sliding angle as low as 14° was obtained for silica film prepared from M = 0.97. The hydrophobic silica films retained their hydrophobicity up to a temperature of 255 °C and above this temperature the films became superhydrophilic. The prepared silica films were characterized by Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM), Fourier Transform Infrared (FT-IR) spectroscopy, humidity test and static and dynamic water contact angle measurements.
