Porous dendritic BiSn electrocatalysts for hydrogenation of 5-hydroxymethylfurfural
(
Royal Society of Chemistry
, 2022 , Article)
The electrocatalytic hydrogenation of 5-hydroxymethylfurfural (HMF) to 2,5-bis(hydroxymethyl)furan (BHMF) is an alternative to conventional heterogeneous catalysis with H2 at high temperatures and pressures. Although Ag ...
Catalytic activity of photocharged binary TiO2 and WO3 membrane filters: Effect of Al2O3 interlayer on direct vs. mediated electron transfers
(
Elsevier
, 2022 , Article)
One of the challenges facing the practical application of photocatalysis is the termination of catalytic reactions in the absence of irradiation. This study synthesizes photo-charged TiO2/WO3 (TW) and TiO2/Al2O3/WO3 (TAW) ...
Versatile Bifunctional and Supported IrNi Oxide Catalyst for Photoelectrochemical Water Splitting
(
MDPI
, 2022 , Article)
Designing a high-performance electrocatalyst that operates with photon-level energy is of the utmost importance in order to address the world’s urgent energy concerns. Herein, we report IrNi nanoparticles uniformly distributed ...
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)) ...
Facile Electrochemical Synthesis of Highly Efficient Copper-Cobalt Oxide Nanostructures for Oxygen Evolution Reactions
(
Electrochemical Society
, 2020 , Article)
Nanostructured copper-cobalt oxide (CuxCo3-xO4, CCO) electrodes are grown directly on conducting substrates via electrochemical deposition; then, various factors (e.g., oxygen vacancies, electrochemically active surface ...
Electrocatalytic arsenite oxidation using iron oxyhydroxide polymorphs (α-, β-, and γ-FeOOH) in aqueous bicarbonate solution
(
Elsevier
, 2020 , Article)
α-, β-, and γ-FeOOH polymorphs have been synthesized and used for electrocatalytic As(III) oxidation into less toxic As(V) in aqueous bicarbonate solution. As-synthesized FeOOH electrodes exhibit unique crystalline structures ...
Standalone photoconversion of CO2 using Ti and TiOx-sandwiched heterojunction photocatalyst of CuO and CuFeO2 films
(
Elsevier
, 2021 , Article)
Artificial photoconversion of carbon dioxide to value-added chemicals remains a challenge. In this work, we synthesize heterojunction copper oxide and copper iron oxide (CuO/CuFeO2; CFO) films on transparent conducting ...
