Recent Developments in Photocatalytic Water Treatment Technology: A Review

Nano-sized TiO 2 photocatalytic water-splitting technology has great potential for low-cost, environmentally friendly solar-hydrogen production to support the future hydrogen economy. Presently, the solar-to-hydrogen energy conversion efficiency is too low for the technology to be economically sound. The main barriers are the rapid recombination of photo-generated electron/hole pairs as well as backward reaction and the poor activation of TiO 2 by visible light. In response to these deficiencies, many investigators have been conducting research with an emphasis on effective remediation methods. Some investigators studied the effects of addition of sacrificial reagents and carbonate salts to prohibit rapid recombination of electron/hole pairs and backward reactions. Other research focused on the enhancement of photocatalysis by modification of TiO 2 by means of metal loading, metal ion doping, dye sensitization, composite semiconductor, anion doping and metal ion-implantation. This paper aims to review the up-to-date development of the above-mentioned technologies applied to TiO 2 photocatalytic hydrogen production. Based on the studies reported in the literature, metal ion-implantation and dye sensitization are very effective methods to extend the activating spectrum to the visible range. Therefore, they play an important role in the development of efficient photocatalytic hydrogen production.

Photocatalysis in water environments using artificial and solar light

A review of photoreactor engineering theory and applications, rigorously derived from chemical reaction engineering principles and radiative energy transport fundamentals, is described. The design procedure is illustrated by presenting the modeling of a continuous flow, annular reactor that is used in a predictive mode. In order to formulate the photochemical reaction rate properly, the radiative transfer equation applied to participating and reactive, homogeneous, and heterogeneous media is presented. We also describe the way by which the effects produced by reflecting surfaces may be incorporated into the rate of reaction and, consequently, into the reactor model. Likewise, a precise formulation to account for polychromatic irradiation is shown. The described methodology provides photoreactor mathematical models that permit an a priori design of a photochemical reactor. Thus, from laboratory data, the scale-up can be performed with no limitations in the size or shape of a large scale application

Photoreactor Analysis and Design: Fundamentals and Applications

Reaction engineering of suspended solid heterogeneous photocatalytic reactors

Precise kinetic studies of photocatalytic reactions in solid catalyst water suspensions require the accurate description of the radiation fieldlight distributioninside the reactor. Solution of the radiative transport equation (RTE) inside the reaction is one of the best ways of accessing to such information. For solving this equation, a minimum of two parameters (the absorption and scattering coefficients) and one scattering spatial distribution function (the phase function) are needed. These attributes are directly associated with the optical behavior of the reacting system and are not independent of catalysts more conventional properties. A complete report on the physical and optical characteristics of titanium dioxide particulate suspensions in water is presented. Results were obtained for six different commercially available powders. The investigated parameters were (i) size of elementary particles, (ii) size of particle aggregates in water suspensions, (iii) specific surface area, (iv) spectral extin...
