Impacts of refining Canadian partially upgraded bitumen: Fluid catalytic cracking

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract In this study, we examine the fluid catalytic cracking (FCC) performance of vacuum gas oil (VGO) from partially upgraded bitumen (PUB), a novel refinery feedstock from Canadian bitumen. FCC experiments were conducted in a lab‐scale FCC unit with VGOs from two different PUBs prepared using thermal cracking and solvent deasphalting, along with ...

A Review of Grain Boundaries: Formation Mechanism, Synthesis Strategy, and Application in Electrocatalysis

open access: yesEcoEnergy, EarlyView.
An overview of grain boundary engineering in the field of electrocatalysis. ABSTRACT Key electrocatalytic reactions such as HER, OER, ORR, CO2RR, and NRR offer promising routes for storing renewable energy as chemical fuels. However, their widespread application is constrained due to the lack of highly active and stable catalysts. Grain boundaries (GBs)

Transition Metal Compounds as Thermochromic Materials: Classification, Properties, Limitations, and Applications

open access: yesEcoEnergy, EarlyView.
This review systematically examines how different transition metal compounds—such as binary and multinary metal oxides, halides, sulfides, and salts—exhibit thermochromism based on the d‐electron configurations of their transition metal cations. It focuses on three main mechanisms of thermochromism: phase transition, charge transfer, and bandgap change.

Design of a Novel CeW/Fe‐TiO2 Catalyst With High Oxygen Vacancy for Enhancing the Reactivity and SO2 Resistance in Low‐Temperature NH3‐SCR Reaction

open access: yesEcoEnergy, EarlyView.
Fe3+ was introduced into the TiO2 lattice using the hydrothermal method, and low‐valent cations replaced part of Ti4+ to generate oxygen vacancies within the Fe‐Ov‐Ti unit, resulting in CeW/Fe‐TiO2 catalysts with oxygen‐deficient structures. Compared with CeW/TiO2 catalyst, the increase in oxygen vacancy content significantly improved the catalytic ...

Enhanced Urea Oxidation Reaction by Mn‐Doped Nickel Hydroxide From Wastewater

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Mn incorporation modifies the hydroxide structure and modulates the electronic properties of the Ni centers, promoting the formation of catalytically active NiOOH species. Mn dopants induce a favorable electronic effect but do not directly participate in the UOR mechanism, enhancing the overall urea oxidation rate and resulting in increased hydrogen ...
