Dual-atom catalysts are at the forefront of latest research because they exhibit outstanding catalytic properties owing to their unique synergistic effects; however, controllable synthesis methods remain limited. In this study, a confinement pyrolysis strategy was used efficiently prepare various dual-atom catalysts.

The synergistic conversion of Miscanthus xGiganteous with sulphated zirconia and dilute hydrochloric acid was investigated. prepared using H2SO4 impregnation characterised X-ray Diffraction (XRD), Energy-dispersive (EDX), Scanning Electron Miscroscope (SEM) spectroscopy nitrogen adsorption–desorption measurements. microwave-assisted reaction evaluated at various temperatures, times catalyst-to-...

AMP-activated protein kinase (AMPK) is a key cellular energy sensor and regulator of metabolic homeostasis. Activation of AMPK provides beneficial outcomes in fighting against metabolic disorders such as insulin resistance and type 2 diabetes. Currently, there is no allosteric AMPK activator available for the treatment of metabolic diseases, and limited compounds are available to robustly stimu...

MIL-101 (Fe) was modified by amino group and doped Cu Co elements microwave hydrothermal method. The effect of SCR denitrification at low temperature investigated with high concentration NOx as adsorption object. results show that when the flue gas is 200 °C up to 1640 mg/m 3 , removal efficiency can reach 86% under optimal conditions, which 1.5 times higher than before modification. In additio...

this research evaluates the efficiency of nanosized zno in the catalytic ozonation of 4-chloro-2-nitrophenol and determines the effect of ph on heterogeneous catalytic ozonation. the combined use of ozone and zno catalyst leads to conversion of 98% 4-chloro-2-nitrophenol during 5 min. in addition, it was found that in zno catalytic ozonation, the degradation efficiency of 4-chloro-2-nitrophenol...

The synthesis and functionalization of imines and amines are key steps in the preparation of many fine chemicals and for pharmaceuticals in particular. Traditionally, metal complexes are used as homogeneous catalysts for these organic transformations. Here we report gold–palladium and ruthenium–palladium nano-alloys supported on TiO2 acting as highly efficient heterogeneous catalysts for the on...

Dual-frequency ultrasound (DFUS) coupled with sonocatalysts has emerged to be an advanced tool for antimicrobial applications in medicine but remains scarcely studied water disinfection. In the present work, we first integrated high-frequency DFUS (120 + 1700 kHz), persulfate (S2O82−) and ZnO nano- (50 nm) microparticles (1 μm) eradicating Escherichia coli Enterococcus faecalis synthetic water....

Fe/Zn oxides promoted with K and Cu selectively produce a-olefins at typical FischerTropsch synthesis conditions (2/1 H2/CO, 1 MPa, and 270°C). The simultaneous presence of K and Cu introduces a synergistic activity enhancement while maintaining the high oletrm selectivity obtained by alkali promotion. Structural and morphological differences in Fe-Zn oxides prepared from ammonium glycolate com...

The present contribution experimentally examined the combined effect of non-thermal plasma and Mn-based composite catalysts on CO2 reforming toluene as a model compound tars in synthesis gas production from biomass gasification pyrolysis. experimentation was performed using fixed-bed reactor packed with catalyst incorporating dielectric barrier discharge (DBD) to generate in-situ. effects speci...

Finding a suitable catalyst is an important research direction in hydrogen (H2) production from water electrolysis. We report synthetic method to obtain IrxCo/C clusters by polyol reduction. The small size and can be evenly distributed. Ir3Co/C cluster had very good activity under acidic conditions. overpotential of the best-performing for oxygen evolution reaction (OER) (HER) only 290 mV 91 wh...
