Minireview on recent advances of application MIPs prepared by precipitation polymerization for recognition target analytes in complex matrices.
A one-pot greener approach towards lignin depolymerization/hydrodeoxygenation is presented. Water was used as a reaction medium with methanol source of reductive equivalents hydrogen in inert atmosphere. Zeolite HZSM-5 and Ni-doped were synthesized at low temperature (95 °C), characterized hydrodeoxygenation catalyst 220 °C. Lignin conversion up to 96.8–98.5% observed highly reduced char formation (<1%). IR, GC-MS ESI-MS spectroscopy characterize the products. The products mainly comprised...
Challenging issues of lignin conversion processes including char formation, lower degree depolymerization and product yield with no selectivity are worked out in this study.
Solvolytic depolymerization of lignin was studied under three different catalytic conditions and explained using a schematic representation the mechanisms.
Kraft lignin from industrial black liquor was subjected to one-pot solvolytic depolymerization and hydrodeoxygenation over zeolite HZSM-5 as catalyst NaOH co-catalyst at 220 °C. The effect of methanol a water–methanol (1 : 1) mixture solvent on the products studied. were characterized by infrared spectroscopy numerical indices based IR spectra product defined study functional group transformations occurring in reaction. Compared pure methanol, found be efficient suppressing char formation...
Carbon Capture and Utilization (CCU) technologies offer a promising avenue for transforming captured CO2 into valuable products, serving as renewable fuels or precursors high-value synthesis. This study explores the dry reforming of methane (DRM) viable pathway to convert CH4 syngas, achieving high equilibrium conversion through use suitable catalysts. Conventional nickel-based catalysts are susceptible carbon deposition, necessitating innovative approaches enhance their performance. A...
In this review, we have systematically discussed diesel particulate composition and its formation, understanding of which is essential to design the effective catalyst compositions. The most commonly used after treatment strategies such as oxidation catalysts, filters, partial flow filters are described followed by chronological category-wise discussions on various groups reported soot catalysts. A detailed review also presented mechanistic kinetics aspects non-catalytic direct matter (PM)...
Chemical looping combustion possesses an inherent advantage of separation CO2 from the carbon based fuels including thermal power plants that would offer effective mitigation emissions through capture and sequestration. In this study, a stable regenerative mixed transition metal oxide Cu Mn (CuMn2O4) is synthesized coprecipitation method tested for multicycle performance oxidation syngas as fuel. It was observed 90% oxygen carrying capacity CuMn2O4 can be utilized with almost 100% conversion...

Abstract In this paper, the performance of SrMn 0.98 B 0.02 O 3 (B = Fe, Ni) perovskites was evaluated for catalytic soot oxidation applications. All samples exhibited a nano-crystalline hexagonal structure (XRD analysis) with crystal sizes ranges 30 to 46 nm. XPS analysis reveals presence multiple valence states Ni cations (Ni 2+ /Ni 3+ ) and Mn (Mn 4+ /Mn divalent strontium trivalent iron cation on surface perovskites. 2 -TPD infers that sample showed highest quantity adsorbed oxygen...
