Journal ArticleDOI
Photoluminescence from Chemically Exfoliated MoS2
Goki Eda,Goki Eda,Hisato Yamaguchi,Damien Voiry,Takeshi Fujita,Mingwei Chen,Manishkumar Chhowalla +6 more
TL;DR: Above an annealing temperature of 300 °C, chemically exfoliated MoS2 exhibit prominent band gap photoluminescence, similar to mechanically exfoliate monolayers, indicating that their semiconducting properties are largely restored.
Journal ArticleDOI
Enhanced catalytic activity in strained chemically exfoliated WS 2 nanosheets for hydrogen evolution
Damien Voiry,Hisato Yamaguchi,Junwen Li,Rafael Silva,Diego C. B. Alves,Takeshi Fujita,Mingwei Chen,Tewodros Asefa,Vivek B. Shenoy,Goki Eda,Manish Chhowalla +10 more
TL;DR: Analyses indicate that the enhanced electrocatalytic activity of WS₂ is associated with the high concentration of the strained metallic 1T (octahedral) phase in the as-exfoliated nanosheets.
Journal ArticleDOI
Nanoporous metal/oxide hybrid electrodes for electrochemical supercapacitors
TL;DR: It is shown that hybrid structures made of nanoporous gold and nanocrystalline MnO(2) have enhanced conductivity, resulting in a specific capacitance of the constituent MnO (2) (~1,145 F g(-1)) that is close to the theoretical value.
Journal ArticleDOI
Conducting MoS2 Nanosheets as Catalysts for Hydrogen Evolution Reaction
Damien Voiry,Maryam Salehi,Rafael Silva,Takeshi Fujita,Mingwei Chen,Tewodros Asefa,Vivek B. Shenoy,Goki Eda,Manishkumar Chhowalla +8 more
TL;DR: By partially oxidizingMoS2, it is found that the activity of 2H MoS2 is significantly reduced after oxidation, consistent with edge oxidation, and 1T MoS 2 remains unaffected after oxidization, suggesting that edges of the nanosheets are not the main active sites.
Journal ArticleDOI
Enhanced Catalytic Activity in Strained Chemically Exfoliated WS2 Nanosheets for Hydrogen Evolution
Damien Voiry,Hisato Yamaguchi,Junwen Li,Rafael Silva,Diego C. B. Alves,Takeshi Fujita,Mingwei Chen,Tewodros Asefa,Vivek B. Shenoy,Goki Eda,Manish Chhowalla +10 more
TL;DR: In this paper, the authors reported atomically thin nanosheets of chemically exfoliated 2H (trigonal prismatic) XS2 as efficient catalysts for hydrogen evolution with very low overpotentials.
