“…4). The 1074 cm -1 band arises from P-O stretching vibrations; the 966 cm -1 band, from W=O stretching vibrations [44]. Thus, the Keggin structure of the HPA persists after the deposition of the acid onto the titanium dioxide surface.…”

“…In the first method, an HPA is introduced at some TiO 2 synthesis stage [39,40]; in the second, an HPA as a colloid, suspension, or film is adsorbed onto off the shelf titanium dioxide [38,41]. HPAs were anchored to a TiO 2 film by heat treating the latter at 300°С [42], 350°С [43], and 400°С [44]. In all cases, HPA deposition accelerated the photochemical oxi dation reaction.…”

For enhancing its photocatalytic activity, titanium dioxide P25 has been modified by adsorption of the heteropoly acid (HPA) H 3 PW 12 O 40 from aqueous solution at an HPA concentration of 0.2 to 5 mmol/L. The deposition of the HPA does not alter the phase composition or morphology of the photocat alyst but only causes a slight change in its diffuse reflectance spectrum. IR spectroscopic and XPS studies have confirmed that the HPA molecules on the TiO 2 surface are intact. The adsorption of the HPA increases the photovoltage and hydroxyl radical yield under UV irradiation. These characteristics reach their maximum values upon the adsorption of the HPA from its 0.5 mmol/L solution. Electrochemical measurements have demonstrated that the HPA increases the rate of interfacial electron transfer. The deposition of the HPA accelerates the gas phase oxidation of acetaldehyde and the degradation of phenol and triethyl phosphate in the aqueous medium. The highest activity is shown by the catalyst obtained by the adsorption of H 3 PW 12 O 40 from its 0.5 mM solution. The results of this study suggest that the HPA is promising for modifying the surface of the TiO 2 photocatalyst.

“…Among these materials, nanocrystalline CdS is a direct band-gap semiconductor material with a reasonable band-gap of 2.4 eV which can effectively absorb the visible light. To date, CdS has been decorated on the TiO 2 system electrodes by different methods, such as electrochemical deposition [17][18][19][20] and sequential-chemical bath deposition (S-CBD) [21][22][23][24]. Recently, Zhang et al [25] reported that uniform CdS/TiO 2 nanotube arrays could be fabricated by the method of successive ion layer adsorption and reaction (SILAR).…”

“…Various semiconductor materials have been investigated as solar water splitting for hydrogen energy conversion such as TiO 2 [1], GaInP [2], WO 3 [3], BiVO 4 [4] and NaTaO 3 [5]. The semiconductor for solar water splitting should have the conduction and the valence band edge positions straddled H + /H 2 and O 2 /H 2 O redox potentials.…”

“…Therefore it was considered that connection of GaN particles can be improved by adding LiNH 2 into GaN particulate film electrode. Another method is a heat-treatment of GaN particulate thin film electrode with TiCl 4 . It has been reported that the connection of particles was improved by this method [23][24][25][26].…”

The photoelectrochemical properties of GaN particulate film electrode on Ti substrate were investigated. GaN particulate film electrode was fabricated by means of doctor blade technique. Two kinds of method were used to improve the connection between GaN particles. One is a heat treatment of GaN particulate thin film with LiNH 2 and another one is a heat treatment with TiCl 4 . From the results of the photoelectrochemical properties, GaN electrodes showed n-type semiconducting behavior in 1.0 M HCl electrolyte under UV irradiation. The high photocurrent response was achieved in the electrode with LiNH 2 treatment and TiCl 4 treatment because of its better connection of each GaN particle.
