“…Ordered mesoporous HPMo-SiO 2 was synthesized by a sol-gel method similar to the described procedure in the literature [23]. Briefly, 2.4 g F127 was completely dissolved in 72 mL of distilled water by vigorously stirring at room temperature, then 0.23 g HPMo (phosphomolybdic acid) was added into the solution.…”

“…materials, some heteropoly acids [21,22] (phosphomolybdic acid and phosphotungstic acid in particular) were added into the synthetic process to change the formation of mesoporous structure. Xu et al [23] synthesized HPMo-SiO 2 using nonionic triblock copolymer F127 (Nonionic triblock copolymer EO106PO70EO106) as a structure directing agent and tetraethyl orthosilicate (TEOS) as a silica source without doing the application experiments. Interestingly, we happened to find HPMo-SiO 2 can adsorb MB, and so far no reports of its application as adsorbent for MB removal.…”

2016): Efficient removal of methylene blue from aqueous solutions by an ordered mesoporous HPMo-SiO 2 , Desalination and Water Treatment, A B S T R A C TAn ordered mesoporous HPMo-SiO 2 was synthesized and used as an adsorbent for removal of methylene blue (MB) from aqueous solutions. The morphology and structures of the material were characterized by scanning electron microscope and transmission electron microscopy. The removal process was systematically investigated under various conditions such as pH value, shaking time, the initial concentration of MB. Adsorption process was closely fitted with pseudo-second-order model and Langmuir isotherm equations. The maximum adsorption capacity for MB was 87.8 mg g −1 at 293 K. The results of thermodynamics studies (ΔG˚< 0, ΔH˚> 0, ΔS˚> 0) showed the adsorption progress was spontaneous and endothermic. Besides, quantitative desorption of MB from HPMo-SiO 2 could be achieved with methanol containing over 25% acetic acid.
