Surface strategies for catalytic CO2 reduction: from two-dimensional materials to nanoclusters to single atoms
This work constructively reviewed and predicted the surface strategies for catalytic CO2 reduction with 2D material, nanocluster and single-atom catalysts
Coupling carbon dioxide reduction with water oxidation in nanoscale photocatalytic assemblies
Closing the photosynthetic cycle on the nanometer scale under membrane separation of the half reactions for developing scalable artificial photosystems.
Solar production of H2O2 on reduced graphene oxide–TiO2 hybrid photocatalysts consisting of earth-abundant elements only
A superior cocatalytic behavior of reduced graphene oxide (rGO) was observed for the photocatalytic production of H2O2 in the TiO2-based system.
TiO2 nanodisks designed for Li-ion batteries: a novel strategy for obtaining an ultrathin and high surface area anode material at the ice interface
A rapid and relatively large-scale production of ultrathin TiO2 nanodisks designed for Li-ion batteries was achieved through a novel and simple sol–gel process occurring at the interface of an organic solvent and ice.
Nafion layer-enhanced photosynthetic conversion of CO2 into
hydrocarbons on TiO2 nanoparticles
A thin Nafion layer on Pd–TiO2 markedly enhances the photosynthetic conversion of CO2 to hydrocarbons (without any sacrificial electron donor) under solar irradiation conditions.
Time-resolved observation of C–C coupling intermediates on Cu electrodes for selective electrochemical CO2 reduction
In real-time measurements, CO dimerization occurred concurrently with CO adsorption (∼5 s), while proton-coupled reduction toward *CHO has slower kinetics (∼30 s).
A highly active, robust photocatalyst heterogenized in discrete cages of metal–organic polyhedra for CO2 reduction
A photocatalyst heterogenized in discrete cages of metal–organic polyhedra provides highly active and robust conversion of carbon dioxide.
N-doped TiO2 nanotubes coated with a thin TaOxNy layer for photoelectrochemical water splitting: dual bulk and surface modification of photoanodes
Thin amorphous TaOxNy layer-coated N-doped TiO2 nanotubes successfully serve as a water splitting photoanode.
Promoting water photooxidation on transparent WO3 thin films using an alumina overlayer
In the water photooxidation process for the artificial photosynthesis, the alumina overlayer on a WO3 photoanode markedly decreases the number of electron trapping sites, eventually facilitating the hole transfer to water.
Tin- porphyrin sensitized TiO2 for the production of H2 under visible light
Hydrogen was successfully produced under visible light irradiation in tin porphyrin (SnP)-sensitized TiO2 system in the wide pH range (pH 3–11) although SnP hardly adsorbs on TiO2.
About this collection
We are delighted to announce that the 2020 EES Lectureship has been jointly awarded to Professor Yana Vaynzof and Dr Wooyul Kim. To celebrate, we have put together collections of Yana and Wooyul’s publications in Royal Society of Chemistry journals.
You are currently reading Wooyul’s collection. You can find Yana’s collection here.
Wooyul has been an Assistant Professor at Sookmyung Women’s University, South Korea, working in the Department of Chemical and Biological Engineering since 2016. He received his PhD from Pohang University of Science and Technology (POSTECH) in 2012, and went on to carry out postdoctoral research at Lawrence Berkley National Laboratory, USA (2012-2016).
His recent research focuses on using time-resolved operando spectroscopy to investigate photo- (and electro-) catalytic mechanisms, including revealing key reaction intermediates, analysing samples used for water reduction and oxidation, and gaining a microscopic perspective of electrode surfaces in photoelectrochemical cells.
