Composition dependent activity of Fe 1−x Pt x decorated ZnCdS nanocrystals for photocatalytic hydrogen evolution

Facile preparation of ZnxCd1−xS/ZnS heterostructures with enhanced photocatalytic hydrogen evolution under visible light

“…13 The highest hydrogen production rate of 2.265 mmol g À1 h À1 was achieved by the 0.5 wt% Fe 0.3 Pt 0.7 -ZnCdS nanocomposites, which was even better than that of 0.5 wt% Pt-ZnCdS (1.626 mmol g À1 h À1 ) under the same condition. 14 The photocatalytic H 2 evolution rate of Zn 0.3 Cd 0.7 S nanorods was improved from 517.4 to 3310.1 mmol g À1 h À1 by loading a suitable amount of Ni 3 C NPs as co-catalyst under visible light irradiation. 15 Hollow Zn 0.6 Cd 0.4 S cage material exhibited the highest hydrogen production rate of 5.68 mmol h À1 g À1 under cocatalyst-free and visible-light irradiation conditions.…”

Formation and Application of Core–Shell of FePt-Au Magnetic–Plasmonic Nanoparticles

“…Compared with non-magnetic NPs, magnetic NPs provide a characteristic of flexible constitution on controlling and manipulation by an external magnetic field to satisfy more biomedical assays. Recently, chemically synthesized iron-based NPs and related core–shell NPs in organic solvents have been extensively studied including fundamental and functional interests due to their attractive optical, electronic, photocatalytic, biological, energy-saving, magnetic resonance imaging (MRI), and magnetic–plasmonic applications (Yavuz et al, 2006 ; Gao et al, 2007 ; Zeng and Sun, 2008 ; Levin et al, 2009 ; Chou et al, 2010 ; Wei and Yao, 2011 ; de la Presa et al, 2012 ; Chen et al, 2013 ; Seemann and Kuhn, 2014 ; Zhuang et al, 2015 ; Mandal and Chaudhuri, 2016 ; Shu et al, 2017 ; Nemati et al, 2018 ; You and Guo, 2019 ; Chan et al, 2020 ). So the simple and reproducible methods to control the crystallite size, composition, and related nanoshell coatings over the magnetic core with tunable plasmonic surface characteristics of the core–shell NPs are very important due to the fact that all potential developments are directly dependent on such corresponding magnetic–plasmonic character statements (Xu et al, 2007 ; Li et al, 2020a ).…”

Contribution of Cation Addition to MnO2 Nanosheets on Stable Co3O4 Nanowires for Aqueous Zinc-Ion Battery

“…The ever-growing demands for electrical energy storage have stimulated the pursuit of advanced energy sources [batteries (Zhang H. et al, 2019 ), supercapacitors (Gan et al, 2020 ), photoelectrocatalysis (Wang et al, 2016 ; Shu et al, 2017 )] with high energy density and high power density as well as high cycle lifetime (Pan et al, 2016 ; Ming et al, 2019 ; Zhang N. et al, 2019 ; Blanc et al, 2020 ). Li-ion batteries (LIBs) have become a protagonist due to their excellent comprehensive performances.…”
