Recent Progress on Titanium Dioxide Nanomaterials for Photocatalytic Applications

Environmental and energy problems have drawn much attention owing to rapid population growth and accelerated economic development. For instance, photocatalysis, "a green technology", plays an important role in solar-energy conversion owing to its potential to solve energy and environmental problems. Recently, many efforts have been devoted to improving visible-light photocatalytic activity by using titanium dioxide as a photocatalyst as a result of its wide range of applications in the energy and environment fields. However, fast charge recombination and an absorption edge in the UV range limit the photocatalytic efficiency of TiO under visible-light irradiation. Many investigations have been undertaken to overcome the limitations of TiO and, therefore, to enhance its photocatalytic activity under visible light. The present literature review focuses on different strategies used to promote the separation efficiency of electron-hole pairs and to shift the absorption edge of TiO to the visible region. Current synthesis techniques used to elaborate several nanostructures of TiO -based materials, recent progress in enhancing visible photocatalytic activity, and different photocatalysis applications will be discussed. On the basis of the studies reported in the literature, we believe that this review will help in the development of new strategies to improve the visible-light photocatalytic performance of TiO -based materials further.

“…To cover the lack of information on activated carbon, the production of activated carbon was introduced into SimaPro so that it could be used as input to calculate the environmental impact of the Pump and Treat and Soil Vapor Extraction techniques. The inputs used for the production of one kilogram of activated carbon are listed in Table 2 and are based on the data found in the papers of Bayer et al [24] and Jeswani et al [25].…”

“…Table 2. Inputs used to model the production process of activated carbon in SimaPro [24,25]. The results of the LCA indicate that overall environmental impact of the chemical alternative ( Figure 2) is larger than the impact of the natural alternative (Figure 3), 155 versus 106 kPt respectively (with kPt = the environmental impact expressed in kilopoints).…”

Chemical or Natural? Including LCA in Social CBA to Compare Remediation Alternatives for a Dry-Cleaning Facility

2019

The choice between remediation alternatives for contaminated sites is complicated by different elements, e.g., the occurrence of multiple contaminants, the extent of the contamination, or the urban location, complicate the choice between remediation alternatives. This paper addresses this challenging choice by analyzing a case study of an extensive soil and groundwater contamination by a dry-cleaning company. For remediating this site, two alternatives were proposed. The first remediation alternative combines several techniques with in-situ chemical oxidization being the most important one. Due to the potential negative impact of this alternative on local residents a second remediation alternative was drawn up, in which the focus lies on the use of stimulated biological degradation. A Life Cycle Assessment (LCA) was performed on both alternatives and showed that the second alternative had a lower environmental impact. The inclusion of monetized LCA results in the calculation of a social Cost-Benefit Analysis (CBA) provided a more extensive view of the secondary environmental costs and benefits of the remediation alternatives. The results of the social CBA allow to conclude that both alternatives are not socially desirable, the chemical alternative however is socially less disadvantageous than the more natural remediation alternative.

“…Sumber arang aktif di Indonesia sebenarnya tidak hanya dari tempurung kelapa namun masih banyak bahan lain yang dapat digunakan seperti tempurung kemiri, limbah sawet, bahan tambang, kayu atau limbah kayu, gambut, hasil pertanian dan limbah peternakan (Arsad dan Hamdi, 2010). Karbon aktif dapat dikatakan "material of the future" karena dapat dikatakan sebagai material dengan banyak fungsi karena manfaat yang sempurpurna untuk dalam berbagai proses penjernihan/ pemulihan/ penyehatan material termasik air (Sirichote et al, 2002), penurunan kadar cafein pada kopi (Marsh and Rodriguez-Reinoso, 2006), penyaringan warna (Li et al, 2015), penghilanga aroma atau bau pada udara (Sahu et al, 2010), pengolahan air minum (Jeswani et al, 2015;Subha and Namasivayam, 2009), industi gas dan pembersihan pendingin udara (Arena, N. et al, 2016). Sebenarnya manfaat karbon aktif dalam air tidak hanya untuk keperluan air minum namun jaga dapat digunakan untuk penyehatan air seperti penyerapan logam berat (Pb, Fe dan Cu), maupun Nitrit dan Phenol (Arsad dan Hamdi, 2010).…”

Carbon Active from Coconut Shell as Tambak Water Quality Increasing The negative impact in intensive cultivation of prawn is the decreasing water quality, caused by the toxic material from food and prawn faces. One alternative to solve that problem is to use the active carbon from coconut shell as adsorbent of toxic material.The aim of these activities is to inform to teach how was adsorption toxic compound by using active carbon running well. The result showed, concentration of H2S in the water dramatically decrease until 0.02 ppm and NH3 until 0.05 ppm and NO2 0,05 ppm. That condition indicates, it was good condition for prawn to life. The conclusion of this public service activity was active carbon from coconut shell can be reduce toxic material and all participant in training very interested approximately 95% of material of training has been understood. Keywords: Carbon active, coconut shell, H2S, NH3, NO2 AbstrakDampak negatif dari budidaya udang secara intensif adalah menurunnya kualitas air tambak karena menumpuknya zat zat beracun yang berasal dari akumulasi sisa pakan maupun kotoran udang. Salah satu alternatif pengendalian kualitas air tambak akibat permasalahan tersebut dengan menggunakan karbon aktif dari tempurung kelapa sebagai bahan absorban. Tujuan dari pengabdian masyarakat adalah untuk memberikan percontohan dan pelatihan kepada petani tambak tentang pemanfaatan arang tempurung kelapa sebagai bahan absorban alami yang berguna meningkatkan kualitas air tambak. Hasil kegiatan yang telah dilakukan meliputi peyuluhan dan percontohan menunjukan 95% masyarakat memahami materi yang diberikan selama penyuluhan. Hal tersebut terlihat dari respon masyarakat dalam bentuk tanya jawab. Sedangkan hasil nyata dari penggunaan arang tempurung kelapa menunjukan kandungan H2S 0,02ppm, NH3 0,05 ppm dan NO2 0,05 ppm. Kandungan zat zat tersebut menunjukan kondisi yang baik untuk hidupnya udang. Kata Kunci: Karbon aktif, tempurung kelapa, H2S, NH3, NO2
