Characteristics of lanthanum loaded TiO2-ZSM-5 photocatalysts: Decolorization and degradation processes of methyl orange

Characteristics of supported nano-TiO2/ZSM-5/silica gel (SNTZS): Photocatalytic degradation of phenol

“…This adsorbed water was probably due to humid KBr and incorporated humidity in the process of sample preparation [28]. Based on the research by Okte et al [29], the peak at wave number near 1102 cm −1 can be attributed to the framework stretching vibration band of Si(Al)-O in tetrahedral Si(Al)O 4 of raw ZSM-5. In SNTZS spectra, the peak appeared at 1106 cm −1 (compared to 1102 cm −1 , the peak shifted slightly upward).…”

Heterogeneous photocatalysis of methylene blue over titanate nanotubes: Effect of adsorption

“…However, due to the complicated separation of suspended ultrafine solid catalysts from the reaction medium, its practical application appears to be difficult so far [3,4]. Immobilization of TiO 2 is an effective strategy to overcome the problem of posttreatment separation [5,6], but it usually diminished photocatalytic activity because of the reduction in available surface area and active surface sites of the catalyst [7].…”

Direct conversion of syngas to dimethyl ether as a green fuel over CuO-ZnO-Al2O3/HZSM-5 nanocatalyst: Effect of aging time on physicochemical and catalytic properties

“…[17][18][19][20] Among various supports used for CZA, zeolites have high surface area, high thermal stability, and eco-friendly nature. [21][22][23] DME synthesis from syngas proceeds through three consecutive reactions, namely, methanol synthesis, methanol dehydration, and water-gas shift reactions as follows: [24][25][26][27] CO þ 2H 2 $ CH 3 OH Methanol synthesis; 2CH 3 OH $ CH 3 OCH 3 þ H 2 O Methanol dehydration;…”
