“…Some of the most enthusiastic researchers, and also pioneers in this field, are Roger A. Sheldon and Martyn Poliakoff, as they have further developed the principles of green chemistry. For instance, Poliakoff and coauthors described the 13 principles of green chemistry and engineering for a greener Africa [15], which are as follows:…”

This review article describes analytical chemistry beyond green chemistry and all efforts that contribute to a more sustainable development. A background is given on sustainable development and green chemistry. Examples of "greening" strategies for sample preparation, chromatography, and detection are given. Thereafter, the review discusses how and why a method or a solvent could be claimed as being "green". Green metrics for analytical chemistry is discussed, including the environment, health, and safety (EHS) index and life cycle assessment (LCA). The choice of solvent and the criteria for a solvent being "green" is also discussed. Finally, sustainable analytical chemistry is described by considering the three important "legs" so as to obtain sustainable development-economic feasibility, societal relevance, and environmental soundness. Hopefully, the review article will stimulate some new perspectives on the difference between greenness and sustainability in analytical chemistry.

“…After many years as an inorganic chemist, I still teach the subject but my research focus has moved to green chemistry, devising cleaner and more sustainable ways of manufacturing chemicals and materials [3,4]. Much of the current work in green chemistry is aimed at finding non-petroleum feedstocks for organic chemicals [5], but we often overlook the fact that humanity is facing a potential shortage of many of the elements themselves.…”

To start this discussion meeting on the new chemistry of the elements held on 12 May 2014, Martyn Poliakoff, Foreign Secretary of the Royal Society, was invited to give the opening remarks. As a chemist and a presenter of the popular online video channel ‘The periodic table of videos’, Martyn communicates his personal and professional interest in the elements to the public, who in turn use these videos both as an educational resource and for entertainment purposes. Ever since Mendeleev’s first ideas for the periodic table were published in 1869, the table has continued to grow as new elements have been discovered, and it serves as both icon and inspiration; its form is now so well established that it is recognized the world over as a symbol for science. This paper highlights but a few of the varied forms that the table can take, such as an infographic, which can convey the shortage of certain elements with great impact.

“…The resulting samples were labeled as ET4-300, ET4-400, ET4-500 and ET4-600 respectively. ii) Loading of raw zeolite ET4 samplewith 20% TiO 2 followed by calcination at 500 o C, labeled 20TET4-500: 1.6 g of ET4 is suspended in a solution of 2.01 mL of titaniumbutoxide (Ti(OBut) 4 ) dissolved in a mixture of 2-propanol (CH 3 CHOHCH 3 ) and water (H 2 O) with volume ratio of 1:10:2 (Ti(OBut) 4 :CH 3 CHOHCH 3 :H 2 O). The suspension was stirred at room temperature for 24 h. The solvent was removed by rotary evaporator and dried at 110 o C. The sample was then calcined in a furnace at 500 o C for 3 h at 3 o C/min.…”

“…Its application nowadays includes photocatalytic environmental treatment, photochemical synthesis and water splitting for energy purpose. Of the many tested photocatalysts, TiO 2 is found to be superb owing to its higher photocatalytic activity, suitable band position, reasonable price and photostability [3][4][5][6][7]. However, TiO 2 shows drawbacks such as narrow excitation wavelength and/or large band gap [8][9][10], fast recombination rate of photogenerated electron-hole pairs [2,[8][9][10] relatively poor adsorption capacity [8,11,12], and difficulties in recycling (recovering) [11,13].…”

ABSTRACT. The combination of zeolites and photochemistry has recently shown excellent results due to the special structure of the zeolites that helps a better use of the solar energy improving the selectivity of the chemical reactions carried out. There are several reports on the preparation of TiO2 confined nanoparticles in synthetic zeolites. However, very few reports are found on the use of natural zeolites. Zeolites are a vast natural resource in Ethiopia that remains unexploited. Their microporous structure can accommodate a wide variety of cations such as sodium, potassium and magnesium among others. The main objective of our work was to test the potential use of the naturally occurring zeolites, with high content in titanium, as photocatalysts. The samples have been characterized by X-ray diffraction (XRD), chemical analysis (ICP-OES), scanning electron microscopy (SEM), diffuse reflectance spectroscopy (UV-Vis) and photocatalytic activities of the samples were tested in photocatalytic degradation of methyl orange (MO).
