Tailoring the defects of sub-100 nm multipodal titanium nitride/oxynitride nanotubes for efficient water splitting performance
(
Royal Society of Chemistry
, 2021 , Article)
Deciphering the photocatalytic-defect relationship of photoanodes can pave the way towards the rational design for high-performance solar energy conversion. Herein, we rationally designed uniform and aligned ultrathin ...
Comprehensive optimization of the dispersion of mixing particles in an inert-particle spouted-bed reactor (Ipsbr) system
(
MDPI
, 2021 , Article)
Effective gas dispersion and liquid mixing are significant parameters in the design of an inert-particle spouted-bed reactor (IPSBR) system. Solid particles can be used to ensure good mixing and an efficient rate of mass ...
CFD and statistical approach to optimize the average air velocity and air volume fraction in an inert-particles spouted-bed reactor (IPSBR) system
(
Elsevier Ltd
, 2021 , Article)
Inert-particles spouted bed reactor (IPSBR) is characterized by intense mixing generated by the circular motion of the inert particles. The operating parameters play an important role in the performance of the IPSBR system, ...
A new process for the recovery of ammonia from ammoniated high-salinity brine
(
MDPI
, 2021 , Article)
This paper describes a new method for the recovery of high-concentration ammonia from water in the form of ammonium chloride, ammonium hydroxide and ammonium carbonate. The method was applied to the Solvay process, in which ...
Chromium removal from tannery wastewater by electrocoagulation: Optimization and sludge characterization
(
MDPI AG
, 2020 , Article)
The treatment of tannery effluent is of great interest as it contains a complexmixture ofpollutants, primarily chromium. The disposal of this wastewater can have adverse effects on the environment and aquatic life, which ...
Adsorption of 4-Nitrophenol onto Iron Oxide Bentonite Nanocomposite: Process Optimization, Kinetics, Isotherms and Mechanism
(
Springer Science and Business Media Deutschland GmbH
, 2022 , Article)
Despite its importance in chemical industry, 4-Nitrophenol (4-NP) is a persistent organic pollutant that has serious effects on the ecosystem. In the present study, Box–Behnken design in response surface methodology was ...
CO2 capture and ions removal through reaction with potassium hydroxide in desalination reject brine: Statistical optimization
(
Elsevier B.V.
, 2022 , Article)
Previous studies have investigated the overall performance of the modified Solvay process based on a new alkaline compound, namely, KOH. Preliminary results have confirmed its high reactivity and effectiveness in capturing ...
Computational fluid dynamics simulation of an Inert Particles Spouted Bed Reactor (IPSBR) system
(
De Gruyter Open Ltd

A novel system for contacting gases and liquids, suitable for many applications involving gas-liquid contact such as CO2 capture and brine desalination, has been simulated and experimentally validated. The system comprises ...
Effective Heterogeneous Fenton-Like degradation of Malachite Green Dye Using the Core-Shell Fe3O4@SiO2 Nano-Catalyst
(
Wiley-Blackwell
, 2021 , Article)
In this study, the application of the core-shell Fe3O4@SiO2 nano-catalysts for fenton-like degradation of malachite green dye has been presented. The nano-catalysts were prepared using a combination of solvothermal and ...
Pt-Based Nanostructures for Electrochemical Oxidation of CO: Unveiling the Effect of Shapes and Electrolytes
(
MDPI
, 2022 , Article)
Direct alcohol fuel cells are deemed as green and sustainable energy resources; however, CO-poisoning of Pt-based catalysts is a critical barrier to their commercialization. Thus, investigation of the electrochemical CO ...
