Synergistic mechanism of Ce-Mn in ZSM-5 carrier catalysts for catalytic oxidation of toluene

Unlocking the potential of V2O5 decorated on crossed g-C3N4 monolayers derived from synergistic bio-transformation of ZnMn2O4 for antibiotic photodegradation

“…2(d), the Mn 2p 3/2 spectrum of (6)ZM was described by three deconvoluted peaks located at 641.0 (Mn 2+ ), 642.9 (Mn 3+ ), and 644.9 (Mn 4+ ) eV, while Mn 2p 1/2 also showed three subpeaks at 652.4 (Mn 2+ ), 654.3 (Mn 3+ ), and 655.9 (Mn 4+ ) eV, demonstrating that the mixed-valence state of Mn facilitated charge carrier transportation to/from reaction centers. 29,44 Similarly, Zn 2p spectrum depicted in Fig. 2(e) showed two unitary peaks for Zn 2p 3/2 (1021.6 eV) and Zn 2p 1/2 (1044.6 eV).…”

Evaluation of machine learning models for predicting TiO2 photocatalytic degradation of air contaminants

“…Artificial neural networks (ANNs) is an established machine learning technique used to forecast properties of many different types of materials, including metals, polymers, composites, and ceramics [40][41][42][43][44][45][46] . ANNs have been used to forecast the photocatalytic activity of novel catalysts [47][48][49][50][51] and to speed up the design and discovery of new catalysts [52][53][54] . Prior research has employed the gaussian process regression model to forecast the band gaps of anatase TiO 2 photocatalysts by considering their surface area and lattice properties 55 .…”

Synthesis of ZSM-5 Zeolites from Quang Ninh Coal Ash Components and Activity for Catalytic Cracking of Low-density Polyethylene

“…Alumina extraction from CFA by acid leaching yields a solid residue which can be converted to Al-rich zeolite 13X and to Si-rich ZSM-5 from the mother liquid of the 13X synthesis process 45) . ZSM-5 prepared from CFA is effective for degradation of toluene after loading with Ce and Mn species by the impregnation method 46) , and methanol-to-olefins 47) and methane-to-methanol oxida-…”
