A high-stability silica–clay composite: Synthesis, characterization and combination with TiO2 as a novel photocatalyst for Azo dye

Synthesis of Ag-loaded Sb2WO6 microsphere with enhanced photocatalytic ability for organic dyes degradations under different light irradiations

“…The BET analysis was carried out to measure surface area and pore structures of as-prepared samples by nitrogen adsorption-desorption at 77 K. Results were depicted in Fig.7 for samples S0-S4. The adsorption-desorption isotherms of all samples can be assigned to type IV isotherm with an H3 type hysteresis loop, indicating the presence of mesopores (2-50nm in size) [27,28]. The hysteresis loops of all the samples shift approach p/p0 = 1, which suggests the presence of macropores (> 50 nm) [29].…”

Clays for heterogeneous photocatalytic decolorization of wastewaters contaminated with synthetic dyes: a review

“…Silica-bentonite has large specific surface (472 m 2 /g) and high hydrothermal stability, which makes it a potential catalyst host-material (Li et al 2009). When loaded with TiO 2 , its photocatalytic results are better than those of pure TiO 2 .…”

Synthesis of TiO2-loaded silicate-1 monoliths and their application for degradation rhodamine B

“…However, when used the nanosized TiO 2 materials to degrade pollutants, many difficulties have been met, such as agglomeration, separation and recovery of ne catalyst particles. 8 As a result, great efforts have been made to improve the photo-efficiency of TiO 2 by dispersing it on solid support materials like glass, 9 optical ber, 10 silica, 11 electrode, 12 clays, 13 stainless steel mesh, 14 and zeolites. 15 Among these, zeolites, as an important series of porous materials, have high specic surface area and physicochemistry stability.…”
