Renewable Hydrogen Production with Steam Reforming of Ethanol Using Siliceous Mesocellular Foam‐Supported Nickel Catalysts

open access: yesAdvanced Energy and Sustainability Research, Volume 4, Issue 11, November 2023., 2023
Herein, the use of nickel catalysts loaded on siliceous mesocellular foam to optimize the ethanol steam reforming reaction based on the aging of the support and the nickel loading is investigated. Fully aged catalyst and 10 wt% nickel loading reach optimal ethanol conversion and hydrogen selectivity from high material porosity, high dispersion of ...

Nickel‐Catalyzed Hydroborylative Polycyclization of Allenynes: an Atom‐Economical and Diastereoselective Synthesis of Bicyclic 5‐5 Fused Rings

open access: yesAdvanced Synthesis &Catalysis, Volume 364, Issue 10, Page 1716-1723, May 17, 2022., 2022
Abstract A diastereoselective synthesis of borylated bicyclic 5‐5 fused ring systems by a domino Ni‐catalyzed hydroborylative polycyclization of allenynes has been developed. The reaction provides two new C−C and one C−B bonds and constitutes an atom‐economical method.

Enhancing Co3O4 nanoparticles: Investigating the impact of nickel doping and high-temperature annealing on NiCo2O4/CoO heterostructures

open access: yesAIMS Materials Science, 2023
In this study, we investigated the phase transition of cobalt spinel (Co3O4) nanoparticles into Co3-xNixO4/CoO heterostructures by introducing varying amounts of nickel (x = 0.0–0.16) and subjecting the particles to high annealing temperatures of 1000 ℃.

Assessment of Pollution in the Central Soils of Khuzestan Province with Potentially Toxic Elements (PTEs) and their Origins [PDF]

open access: yesمجله آب و خاک, 2023
Introduction In recent years, soil contamination with potentially toxic elements (PTEs) has become a major problem in most parts of the world. PTEs are naturally generated from the pedogenesis in the soil and are formed mainly by rock weathering ...
