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
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
Cu and Cu-Based Nanoparticles: Synthesis and Applications in Catalysis.
Manoj B. Gawande,Anandarup Goswami,François-Xavier Felpin,Tewodros Asefa,Xiaoxi Huang,Rafael Silva,Xiaoxin Zou,Radek Zboril,Rajender S. Varma +8 more
TL;DR: A critical appraisal of different synthetic approaches to Cu and Cu-based nanoparticles and copper nanoparticles immobilized into or supported on various support materials (SiO2, magnetic support materials, etc.), along with their applications in catalysis.
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.
Journal ArticleDOI
Periodic mesoporous organosilicas with organic groups inside the channel walls
TL;DR: In this article, a periodic mesoporous organosilica containing bridge-bonded ethene groups directly integrated into the silica framework is described, which is able to solvent-extract and ion-exchange the surfactant templates to create a stable and periodic mesophorous ethenesilica.
