“…Researchers developing plasmonics perceived a possible breakthrough in plasmonic photocatalytic reactions after the work presented by Awazu et al [3]. Several studies and reviews related to plasmonic photocatalytic reactions have been published, particularly in the past 3 years [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21].…”

Plasmonic photocatalytic reactions have been substantially developed. However, the mechanism underlying the enhancement of such reactions is confusing in relevant studies. The plasmonic enhancements of photocatalytic reactions are hard to identify by processing chemically or physically. This review discusses the noteworthy experimental setups or designs for reactors that process various energy transformation paths for enhancing plasmonic photocatalytic reactions. Specially designed experimental setups can help characterize near-field optical responses in inducing plasmons and transformation of light energy. Electrochemical measurements, dark-field imaging, spectral measurements, and matched coupling of wavevectors lead to further understanding of the mechanism underlying plasmonic enhancement. The discussions herein can provide valuable ideas for advanced future studies.

“…The nano-TiO 2 facilitates the degradation under sunlight radiation with O 2 −2 as dominant oxidizing species. The better degradation efficiency was at pH 2.6, and correspondent with the pseudo-first-order without nanoparticles was one or two orders small with λ = 365 nm of radiation using pristine nanotubes [10].…”

Environmental sustainability demands the advancement in water treatment and the use of lighting natural resources. Brazil has one of the most stable and intense solar irradiation in the world. It has to be used not only for energy generation purposes but also and mostly for water treatment, water quality polishment, and furthermore water disinfection. The chapter performs a comparison of different green technologies for water treatment as natural solar irradiation, simulated solar photolysis, solar photo-Fenton with and without hydrogen peroxide addition (solar/ Fe), solar photo-Fenton with and without peroxide (solar/Fe/H 2 O 2), titanium oxide-mediated photocatalysis (UV/TiO 2), photolysis under UV irradiation, and UV treatment with hydrogen peroxide (UV/H 2 O 2). The chapter describes the solar photodecomposition calculations for pharmaceuticals and the emerging pollutants mostly found in polluted waters, including the decomposition route, kinetics, and process parameters. Many published works to point out the important properties to evaluate catalyzer and semiconductor materials after their use in photodecomposition processes. The essay includes the solar photodecomposition of dyes, carbamazepine, hormones, acetaminophen, antipyrine, bisphenol A, antibiotics, and the photodecomposition by-products. Finally, the chapter presents the synergistic effect between them with the probable mechanism and mineralization degree.

“…These results suggest that the simple method at lower temperatures for obtaining α-Fe 2 O 3 particles may be used for BPA removal whose efficiency is almost identical to α-Fe 2 O 3 fibers obtained by more demanding process. BPA degradation has been found to be predominantly achieved via direct oxidation as well due to OH • oxidation which are the major oxidants that degrade BPA [20,1]. The most possible pathways are presented in Fig.…”

“…In the context of environmental protection, iron-enriched clay catalysts even at lower activity have an advantage over homogeneous iron catalysts which can be further improved by increasing the iron content [18,19]. In addition, the photocatalysts should be easily separable from the water, in order to improve the ease of recycling and reusing the photocatalysts [20].…”

The electrospinning process was used to prepare iron oxide fibers, named Fe 2 O 3 fiber. Morphological and structural properties of samples were determined by Scanning Electron Microscopy (SEM), X-ray diffraction (XRD), Fourier Transform Infra-Red (FT-IR) and BET/BJH analysis. It was found that the α-Fe 2 O 3 phase (hematite) has shown the compaction of the structure at 700 o C, i.e. lower textural properties. Hematite particles and fibers are used for bisphenol A (BPA) removal by photocatalytic decomposition and the enhanced catalytic performance was found with the use of Fe 2 O 3 400 o C particles.
