Abstract Mesoporous, bifunctional MgO-SnO 2 nanocatalysts with enhanced surface area are used for producing biodiesel from waste cooking oil. Biodiesel yield of 80% is achieved within the first 20 min when transesterification carried out at an optimum condition 18:1 methanol to oil ratio, wt% nanocatalyst, and a reaction temperature 60 °C. The conversion gives maximum 88% allowed continue 120 m...

In this paper, we report a new concept to construct a label-free electrochemical inhibition-based immunosensor for the detection of the mycotoxin deoxynivalenol (DON) in cereal samples. The electrochemical impedance spectroscopy of tris(bipyridine) ruthenium (II) chloride was used as a marker enhanced with gold nanoparticles-dotted 4-nitrophenylazo functionalized graphene (AuNp/G/PhNO2) nanocat...

Low power consumption and minimal potential hazards are ultimate goals for the modern development of chemical manufacturing; however, it often reduces the selectivity of chemical reactions by implementing a new reaction system. A nanocatalyst design is reported for achieving efficient and selective alkyne semihydrogenation through the photocatalytic hydrogen transfer from water, which avoids th...

Compositional heterogeneity in shaped, bimetallic nanocrystals offers additional variables to manoeuvre the functionality of the nanocrystal. However, understanding how to manipulate anisotropic elemental distributions in a nanocrystal is a great challenge in reaching higher tiers of nanocatalyst design. Here, we present the evolutionary trajectory of phase segregation in Pt-Ni rhombic dodecahe...

Recently, TiO2/multi-walled carbon nanotube (MWCNT) hybrid nanocatalysts have been a subject of high interest due to their excellent structures, large surface areas and peculiar optical properties, which enhance their photocatalytic performance. In this work, a modified microwave technique was used to rapidly synthesise a TiO2/MWCNT nanocatalyst with a large surface area. X-ray powder diffracti...

The aim of this research work is Synthesis ZnO/SiO2 with Palash leaves extract nanocatalyst by green synthesis route. contain a broad variability bio-molecules which act as capping and reducing agents increases the rate reduction stabilization nanoparticles. Nanocatalyst synthesized method are eco-friendly cheap. No has been found on Butea monosperma (Palash) ZnO This palash extracts nanocataly...

The promoted K-La nanocatalysts supported on ZSM-5 zeolite were prepared via wetness impregnation method and tested for biodiesel production from soybean oil. The effects of different weight percentage of La, loading of K as a promoter and calcination conditions on structure and activity of catalyst were investigated. Results showed that the supported catalyst containing 7wt.% of La was pro...
