Application of perovskites towards remediation of environmental pollutants: an overview

Scouting contaminated estuaries: Heavy metal resistant and plant growth promoting rhizobacteria in the native metal rhizoaccumulator Spartina maritima

“…Bacteria containing this enzyme reduce the level of ACC in the stressed plants thereby limiting the damage to the plant (Penrose and Glick, 2003). Finally, there are reports on the application of biofilms for the removal of heavy metals (Das et al, 2012). Heavy metal bioremediation can be achieved by immobilisation, concentration and partitioning to an environmental compartment, thereby minimizing the anticipated hazards (Barkay and Schaefer, 2001;Lloyd, 2003).…”

Moving closer towards restoration of contaminated estuaries: Bioaugmentation with autochthonous rhizobacteria improves metal rhizoaccumulation in native Spartina maritima

“…Regarding bacteria containing the enzyme 1-aminocyclopropane-1-carboxylate (ACC) deaminase, they can cleave the plant ethylene precursor ACC and thereby diminish the level of ethylene in a developing or stressed plant, thus limiting the damage to the plant [41]. Finally, there are reports on the application of biofilms for the removal of heavy metals [42]. They are kept immobilised, concentrated and partitioned to an environmental compartment, minimizing the anticipated hazards [43].…”

Perovskite catalysts for methane combustion: applications, design, effects for reactivity and partial oxidation

“…They indicated reaction conditions as 10 vol% CH 4 , 25 vol%O 2 , and Ar as balance gas, with a space velocity of 24,000 mL g -1 h -1 . 153 The above-mentioned preparation methods can be summarized as follows 154 :…”

“…[155][156][157] • Hydrothermal synthesis is a method of preparing perovskite, which facilitates crystal growth under conditions of high pressure and temperature in solvent conditions from the insoluble materials at normal pressure (<1 atm) and temperature (<100°C). 154 This method has been studied extensively in the literature. [158][159][160] • The precipitation of the multicomponent system is called co-precipitation.…”

“…• The sol-gel method is a known procedure for the preparation of colloidal nanoparticles from the liquid phase and is frequently used in the industry for the production of nanomaterials. 70,154,163,164 Batis et al 165 prepared the La 1-x Ca x MnO 3±y (0 ≤ x ≤ 1; -0.04 ≤ y ≤ 0.24) oxides to understand the role of physicochemical properties of pure and calcium substituted lanthanum manganite perovskite in CH 4 combustion. The authors reported physicochemical characteristics of La 1-…”
