The supplementary data have included a full range of TEM pictures of the post-run samples, including 400 oC calcinated MoO3/H-ZSM-5 samples (coked) and the parent H-ZSM-5 (coked), showing the distribution of Mo clusters on the zeolite crystallite external surface, and the observed coke deposition upon the spreading of the Mo species. The Figures S1-S9 are the complementary of the Fig. 8 in the ...

Cu-SSZ-13 has been characterized by different spectroscopic techniques and compared with Cu-ZSM-5 and Cu-β with similar Si/Al and Cu/Al ratios and prepared by the same ion exchange procedure. On vacuum activated samples, low temperature FTIR spectroscopy allowed us to appreciate a high concentration of reduced copper centres, i.e. isolated Cu(+) ions located in different environments, able to f...

γ-Valerolactone (GVL) is one of the useful biomass compounds produced via different reaction pathways from hemicellulose. In this study, Co- and Pt-doped/ZSM-5 catalysts with Co loadings (0–10 wt.%) Pt (0.5–2 were prepared by impregnation method employed in a one-pot conversion furfural to GVL. The yield GVL increased increasing temperature 100 140 °C. At 120 °C, higher amounts secondary produc...

Hierarchical micro-mesoporous ZSM-5 (MFI type) zeolite was synthesized by using corn plant stem pith powder from agricultural waste as hard template under simple hydrothermal method. The additional porosity generated this into the zeolites precursor gel yielded hierarchical (C-ZSM-5). Conventional micro porous (ConvZSM-5) also prepared same procedure without adding to compare catalytic performa...

ZSM-5 is an important class of acid catalyst for producing bio-oil rich in petrochemicals; however, continuous efforts are required to improve the conversion efficiency biomass-derived oxygenates with large molecular sizes. The mesoporous (N-ZSM-5) was prepared a post-treatment method nanocellulose as green template this study induce additional surface and porous features. promoted properties N...

Photolysis of the supramolecular complexes (dibenzyl ketones@ZSM-5) produced supramolecular complexes of benzyl radicals@ZSM-5, which were directly detected by CW-EPR spectroscopy, and provided information on the dynamics of the radicals. The lifetimes of the radicals increased as the group X attached to the carbon atom at the radical center increases from X = H (t(1/2) ca. 2 min) to X = (CH(2)...

Photodynamic therapy (PDT) is a method that combines the use of nontoxic components, namely photosensitizer, light and oxygen to cause localised oxidative photo-induced damage. The aim of this study was to contribute to PDT development by studying an alternative light sources using red light-emitting diode (LED) light and evaluated its effect on the photodynamic activity of methylene blue (MB) ...

ABSTRACT Hierarchical ZSM-11 and Zn-ZSM-11 catalysts were used in this study. The effects of two methods (direct synthesis and impregnation) of zinc incorporation on methanol conversion were investigated in a continuous-flow isotherm fixed-bed reactor. XRD, SEM, BET, FTIR, and XRF analytical results revealed that the introduction of zinc through direct synthesis generated new Brønsted acid site...

Alkaline protease from brinjal leaf (Solanum melongena) having milk clotting activity has been purified to 9.44 fold to a final specific activity of 45.71 U/mg. SDS-PAGE of the final preparation revealed a single protein band of approx 14 kDa. Purified enzyme was characterized and was successfully immobilized into the amorphous mesoporous silica (SBA-15) and crystalline mesoporous zeolite (Nano...

Direct catalytic conversion of ethanol to hydrocarbon blend-stock can increase biofuels use in current vehicles beyond the ethanol blend-wall of 10-15%. Literature reports describe quantitative conversion of ethanol over zeolite catalysts but high C2 hydrocarbon formation renders this approach unsuitable for commercialization. Furthermore, the prior mechanistic studies suggested that ethanol co...
