Ion-Enhanced Conversion of CO2 into Formate on Porous Dendritic Bismuth Electrodes with High Efficiency and Durability
(
Wiley-VCH Verlag
, 2019 , Article)
Facile synthesis of efficient electrocatalysts that can selectively convert CO2 to value-added chemicals remains a challenge. Herein, the electrochemical synthesis of porous Bi dendrite electrodes and details of their ...
Membrane Distillation Crystallization Hybrid Process for Zero Liquid Discharge in QAFCO Plant
(
Qatar University Press
, 2021 , Poster)
Qatar fertilizer company (QAFCO) is one of the world’s largest single site producer of ammonia and urea with production capacity of 12,900 metric tons per day. Currently, QAFCO faces major challenges in terms of water ...
Simultaneous CO2 treatment and blue energy generation from wasted industrial streams
(
Qatar University Press
, 2021 , Poster)
In the last decade, there has been an increased global need for finding bright solutions to tackle industrial wastes and emissions release. Herein, this work explores the utilization of a compact Reverse Electrodialysis ...
Lithium capture in seawater reverse osmosis (SWRO) brine using membrane-based capacitive deionization (MCDI) system
(
Qatar University Press
, 2021 , Poster)
Lithium-battery based industries including vehicles, electronics, fusion and thermonuclear, consume lithium rapidly, which raises the need for developing a lithium recovery system. Lithium global market consumption in 2016 ...
Facile and Novel LiAlO2 Film Electrodes for Energy Efficient Li recovery from Seawater Reverse Osmosis (SWRO) Brine
(
Qatar University Press
, 2021 , Poster)
Concentration of Li in seawater is too low at 0.17 ppm despite its high content altogether with a reported 230 billion tons. Hence, seawater is not a practical source to recover Li from; Li is largely extracted by solar ...
Salinity gradient energy generation by pressure retarded osmosis: A review
(
Elsevier B.V.
, 2021 , Article)
Pressure retarded osmosis (PRO) has gained attention due to its use as a salinity gradient energy-generating membrane process. This process can convert difference in salinity between two streams into energy as it allows ...
Thermo-osmosis-Coupled Thermally Regenerative Electrochemical Cycle for Efficient Lithium Extraction
(
American Chemical Society
, 2021 , Article)
Lithium (Li) production based on the soda evaporation process is time-consuming and unsustainable. The emerging electrochemical Li extraction is time-efficient but requires high-concentration Li sources and significant ...
Electrocatalytic arsenite oxidation in bicarbonate solutions combined with CO2 reduction to formate
(
Elsevier
, 2020 , Article)
Sunlight-driven water-energy nexus technologies are receiving increasing attention. This study presents a hybrid electrochemical system that catalyzes the oxidation of As(III) to As(V) with a nanoparticulate TiO2 electrocatalyst ...
Control of the antagonistic effects of heat-assisted chlorine oxidative degradation on pressure retarded osmosis thin film composite membrane surface
(
Elsevier
, 2021 , Article)
During pressure retarded osmosis (PRO) operation, thin film composite (TFC) membranes are continuously exposed to chemicals present in the stream that can deteriorate the membrane's selective layer with exposure time. ...
In Situ-Generated Reactive Oxygen Species in Precharged Titania and Tungsten Trioxide Composite Catalyst Membrane Filters: Application to As(III) Oxidation in the Absence of Irradiation
(
American Chemical Society (ACS)
, 2020 , Article)
This study demonstrates that in situ-generated reactive oxygen species (ROSs) in prephotocharged TiO2 and WO3 (TW) composite particle-embedded inorganic membrane filters oxidize arsenite (As(III)) into arsenate (As(V)) ...
