Journal ArticleDOI
Molybdenum phosphide as an efficient electrocatalyst for the hydrogen evolution reaction
Peng Xiao,Mahasin Alam Sk,Larissa Thia,Xiaoming Ge,Rern Jern Lim,Jing-Yuan Wang,Kok Hwa Lim,Xin Wang +7 more
TL;DR: In this article, the authors proposed a cost-effective molybdenum phosphide that exhibits high activity towards the hydrogen evolution reaction (HER) in both acid and alkaline media even in bulk form.
Journal ArticleDOI
Revealing the tunable photoluminescence properties of graphene quantum dots
TL;DR: Using density functional theory (DFT) and time-dependent DFT calculations, Wang et al. as discussed by the authors revealed that the photoluminescence mechanism of a GQD can be sensitively tuned by its size, edge configuration, shape, attached chemical functionalities, heteroatom doping and defects.
Journal ArticleDOI
Facile Synthesis of Graphene Quantum Dots from 3D Graphene and their Application for Fe3+ Sensing
Arundithi Ananthanarayanan,Xuewan Wang,Parimal Routh,Barindra Sana,Sierin Lim,Dong-Hwan Kim,Kok Hwa Lim,Jun Li,Peng Chen +8 more
TL;DR: In this article, a facile method to electrochemically exfoliate GQDs from three-dimensional graphene grown by chemical vapor deposition (CVD) is reported, which is used for sensitive and specific detection of ferric ions.
Journal ArticleDOI
A review on the electrochemical reduction of CO2 in fuel cells, metal electrodes and molecular catalysts
TL;DR: In this paper, the development and utilisation of fuel cells, metal electrodes in aqueous electrolyte and molecular catalysts in the electrochemical reduction of CO2 was reported.
Journal ArticleDOI
CH3O decomposition on PdZn(111), Pd(111), and Cu(111). A theoretical study.
TL;DR: Calculated results showed that the decomposition of methoxide to formaldehyde is thermodynamically favored on Pd(111), but it is an endothermic process on P dZn(111) and Cu( 111) surfaces.
