Synthesized TiO2/ZSM-5 composites used for the photocatalytic degradation of azo dye: Intermediates, reaction pathway, mechanism and bio-toxicity

Precise control of the size of zeolite B-ZSM-5 based on seed surface crystallization

“…In the micro-synthesis system (e.g. D 0 is 14.2 mm), when the size of seed is smaller than 300 nm, eqn (7) can be simplied into eqn (8), which agree with the relationships shown in Fig. 7 (eqn (3)).…”

“…ZSM-5-type zeolites offer tunable acidity, shape selectivity and hydrothermal stability, leading to their wide use in catalytic operations, [1][2][3][4] such as alkylation, 5 methane oxidation, 6 methane aromatization, 7 environmental catalysis, [8][9][10][11] Fischer-Tropsch synthesis 12 and methanol to hydrocarbon (MTP, [13][14][15] MTO, 16 MTA 17 etc.) reactions.…”

Improved Self-Cleaning Properties of Photocatalytic Gypsum Plaster Enriched with Glass Fiber

“…In photocatalytic tests, organic dyes are often used as model pollutants because of their complex structure and simplicity in monitoring their degradation rate [20]. Especially, azo dyes show their dominance in global production (50–70% of the textile market) [21].…”

Comparison of four oxidants activated through tetraacetylethylenediamine for developing sustainable and rapid degradation of organic dye

“…1,2 This has posed an increasingly serious problem for both the natural environment and human health due to their non-biodegradability and significant mutagenic and carcinogenic effects. 3,4 Although many techniques have been proposed to remove or decompose organic dyes from wastewater, several oxidative degradation processes using different oxidising agents such as hydrogen peroxide, [5][6][7][8] hypochlorite, 9,10 peroxysulphates [11][12][13] and ozone 14,15 have been found to be more effective than the other methods, mainly because the organic dyes can be broken down and completely mineralised to carbon dioxide and water by the oxidants under optimal conditions. However, most of these technologies are often more time-or energy-consuming, require a complicated and high-cost process, or produce secondary pollution, which is often a result of using iron compounds as photocatalysts under light irradiation, particular in photo-Fonten reactions.…”
